It’s all about the stuff: collections, interfaces, power and people

This is the full version of a paper I presented at the National Digital Forum, 30 November 2011.

In 1901, one of the first acts of the Commonwealth of Australia was to create a system of exclusion and control designed to keep the newly-formed nation ‘white’. But White Australia was always a myth. As well as the Indigenous population, there were already many thousands of people classified as ‘non-white‘ living in Australia — most were Chinese, but there were also Japanese, Indians, Syrians and Indonesians.

Here are some of them…

The real face of White Australia

The administration of what became known as the White Australia Policy created a huge volume of records, much of which is still preserved within the National Archives of Australia. These photographs are attached to certificates that non-white residents needed to get back into the country if they decided to travel overseas. There are thousands upon thousands of these certificates in the Archives. Thousands of certificates representing thousands of lives — all monitored and controlled.

But is is too easy to see these people as the powerless victims of a repressive system. There were many acts of resistance. Some argued against the need to be identified ‘just like a criminal’. Others exercised control over their representation, submitting formal studio portraits instead of mug shots.

Most commonly and most powerfully, people resisted the policy simply by going ahead and living rich and productive lives.

My partner, Kate Bagnall, is helping to rewrite Australian-Chinese history by overthrowing the stereotype of the culturally isolated Chinese man living a lonely, meagre existence surrounded by gambling and opium dens. By mining the available records, by reading against the grain of contemporary reports and by working with family historians, Kate is documenting their intimate lives — their wives, their lovers, their families and descendants — the sorts of relationships that sent a shudder through the edifice of White Australia. Power can be reclaimed in many subtle and subversive ways.

‘The real face of White Australia’ is an experiment. It uses facial detection to technology to find and extract the photographs from digital copies of the original certificates made available through the National Archives of Australia’s collection database. The photographs you see here come from just one series, ST84/1. There’s no API to the collection so I reverse-engineered the web interface to create a script that would harvest the item metadata and download copies of all the digitised images. There are 2,756 files in this series. On the day I harvested the metadata, 347 of those files had been digitised, comprising 12,502 images. It took a few hours, but I just ran my script and soon I had a copy of all of this in my local database.

Then came the exciting part. Using a facial detection script I found through Google and an open source computer vision library, I started experimenting with ways of extracting the photos. After a few tweaks I had something that worked pretty well, so I pointed my aging laptop at the 12,502 images and watched anxiously as the CPU temperature rose and rose. It took a few emergency cooling measures, but the laptop survived and I had a folder containing 11,170 cropped images. About a third of these weren’t actually faces, but it was easy to manually remove the false positives, leaving 7,247 photos.

These photos. These people.

With my database fully primed and loaded it was just a matter of creating a simple web interface using Django for the backend and Isotope (a jQuery plugin) at the front. Both are open source projects. All together, from idea to interface, it took a bit more than a weekend to create, and most of that was waiting for the harvesting and facial detection scripts to complete. It would be silly to say it was easy, but I would say that it wasn’t hard.

What we ended up with was a new way of seeing and understanding the records — not as the remnants of bureaucratic processes, but as windows onto the lives of people. All the faces are linked to copies of the original certificates and back to the collection database of the National Archives. So this is also a finding aid. A finding aid that brings the people to the front.

According to Margaret Hedstrom the archival interface ‘is a site where power is negotiated and exercised’. Whether in a reading room or online, finding aids or collection databases are ‘neither neutral nor transparent’, but the product of ‘conscious design decisions’. We would like to think that this interface gives some power back to the people within the records. Their photographs challenge us to do something, to think something, to feel something. We cannot escape their discomfiting gaze.

But this interface represents another subtle shift in power. We could create it without any explicit assistance or involvement by the National Archives itself. Simply by putting part of the collection online, they provided us with the opportunity to develop a resource that both extends and critiques the existing collection database. Interfaces to cultural heritage collections are no longer controlled solely by cultural heritage institutions.

It’s these two aspects of the power of interfaces that I want to focus on today.

There are a growing number of examples where the records created by repressive or discriminatory regimes have, in Eric Ketelaar’s words, ‘become instruments of empowerment and liberation, salvation and freedom’. Nazi records of assets confiscated during the Holocaust have been used to inform processes of restitution and reparation. Government records have helped members of Australia’s Stolen Generations trace family members. Descendants of inmates incarcerated by American colonial authorities in what was the world’s largest leprosy colony in the Philippines, have embraced the administrative record as an affirmation of their own heritage and survival. Records can find new meanings. Power can be reclaimed.

Technology can help. Tim Hitchcock has described how something as simple as keyword searching can turn archives on their heads. Recordkeeping systems tend to reflect the structures and power relations of the organisations that create them. The ‘hierarchical and institutional nature of most archives’, Hitchcock argues, ‘contains an ideological component which is sucked in with every dust-filled breath’. But digitisation and keyword searching free us from having to follow the well-worn paths of institutional power. We can find people and follow their lives against the flow of bureaucratic convenience. We can gain a wholly new perspective on the workings of society. ‘What changes’, Hitchcock asks, ‘when we examine the world through the collected fragments of knowledge that we can recover about a single person, reorganised as a biographical narrative, rather than as part of an archival system?’

Projects such as Unknown no longer may help us answer that question.

Unknown no longer

It’s aiming to extract the names and biographical details of slaves from the 8 million manuscript documents held by the Virginia Historical Society. The documents include court records, receipts, wills and inventories. Here is a page from the ‘Inventory of Negroes at Berry Plain Plantation, King George County, Virginia’ for 1855, listing names, occupations and valuations.

Tim Hitchcock is one of the directors of London Lives a project that similarly seeks to find the people in 240,000 manuscript pages documenting the lives of plebeian Londoners in the 17th century.

London Lives

More than three million names have already been extracted from the records of courts, workhouses, hospitals and other institutions. Work is continuing to link these names together, to merge these various shards of identity and piece together the experiences of London’s poorest inhabitants.

Remember me from the US Holocaust Memorial Museum is working with photographs taken by relief agencies in the aftermath of World War Two. The photographs are of displaced children who survived the Holocaust but were separated from families. What happened to them? The project is seeking public help to identify and trace the children.

Remember me

These are all projects about finding people. Finding the oppressed, the vulnerable, the displaced, the marginalized and the poor and giving them their place in history. This is what Kate and I hope to do with Invisible Australians, the broader project of which our faces experiment is part.

Invisible Australians

‘Invisible Australians’ aims to extract more than just photographs. We want to record and aggregate the biographical data contained within the records of the White Australia Policy — to extract the data and rebuild identities.

But we want to do more, we want to link these identities up with with other records, with the research of family and local historians, with cemetery registers and family trees, with newspaper articles and databases we don’t even know about yet. We want to find people, families and communities.

It’s ridiculously ambitious and totally unfunded. But it is possible.

The most exciting part of online technology is the power it gives to people to pursue their passions. As with the faces, we don’t need the help of the National Archives. We need the records to be digitized, but that’s happening anyway and we can afford to be patient. Most of the tools we need already exist, and are free. In the past 12 months, for example, there have been a number of open source tools released for crowd-sourced transcription of manuscript records.

People with passions, people with dreams, people who are just annoyed and impatient, don’t have to wait for cultural institutions to create exactly what they need. They can take what’s on offer and change it.

Interfaces can be modified. It is amazingly easy to write a script that will change the way a web page looks and behaves in your browser. I was frustrated by the standard interface to digitized files in the National Archives of Australia’s Recordsearch database — so I changed it.

Before and after

Not only did make it look a bit nicer, I added new functions. My script lets you print a whole file or a range of pages and display the entire contents of the file on a pretty cool 3d wall.

I’ve shared this script, and a few other Recordsearch enhancements. Anyone can install them with a click and use them.

Wragge Labs Emporium

Interfaces are sites of power and we can claim some of that power for ourselves. Online technologies not only free us from the having to brave the physical intimidation of the reading room, they free us up to engage with the records in new ways. The archivist-on-duty would probably not be pleased if I pulled out some scissors and started snipping photos out of certificates. Or if I pulled a file apart and pasted it’s contents on the wall. But online we are free to experiment.

The power of cultural heritage organisations is perhaps expressed most forcefully in their ability to control the arrangement and description of their collections. ‘Every representation, every model of description, is biased’, note Verne Harris and Wendy Duff, ‘because it reflects a particular world-view and is constructed to meet specific purposes’. Archives, libraries and museums are already starting to share this power, by allowing tagging, or seeking public assistance with description through crowd sourcing projects. But most of the these activities still happen within spaces created and curated by the institutions themselves. Our cathedrals of culture might be opening their doors and inviting the public to participate in their ceremonies, but that doesn’t make them bazaars. The architecture stills speaks of authority.

In any case, people already have a space where they can explore and enrich collections — it’s called the internet.

It would be great to see cultural institutions doing more to watch, understand and support what people are doing with collections in their own spaces — following them as they pursue their passions, rather than thinking of ways to motivate them.

A quick example… You might have heard of Zotero, it’s an open source project that lets you capture, annotate and organize your research materials.

Zotero

One cool thing about Zotero is that you can build and contribute little screen scrapers, called translators, that let Zotero extract structured data from any old collection database. You might not be surprised to learn that I’ve created a translator for Recordsearch. Another cool thing about Zotero is that you can share the stuff that you collect in public groups.

Invisible Australians Zotero group

Put those two cool things together and what do you have? Well to me they spell out user generated finding aids — parallel collection databases created by researchers simply pursuing their own passions.

Linked Open Data greatly increases opportunities for collection description to leak into the wider web. If objects and documents are identified with a unique URL, then anyone can can make and publish statements about them in machine-readable form. These statements can then be aggregated and explored. Initiatives such as the Open Annotation Collaboration will hasten the development of these shared descriptive and interpretative layers around our cultural collections.

And of course all this descriptive and interpretative work can be harvested back to enhance existing collection databases. We could start doing it now — though I will spare you today my rant about the possibilities of mining footnotes.

As well as exploring the possibilities of user-generated content, cultural institutions are starting to open up their collection data for re-use. APIs are great (though Linked Open Data is better), and New Zealand is lucky to have an organisation like DigitalNZ which just gets it. People can and will make cool things with your stuff.

But again, we don’t have to wait for everything to be delivered in a convenient, machine-readable form. If it’s on the web anybody can scrape, harvest and experiment.

You probably all know about the National Library of Australia’s newspaper digitisation project — it’s building a magnificent resource. But I wanted to do more than just find articles. I wanted to explore and analyze their content on a large scale. So I built a screen scraper to extract structured data from search results, and then used the scraper to  power a series of tools. I have a harvester that lets you download an entire results set — hundreds or thousands of articles — with metadata neatly packaged for further analysis.

Harvester

Or what about a script that graphs the occurrence of search terms over time, and allows you to ask questions like When did the Great War become the First World War?.

When did the Great War become the First World War?

In the end I got a bit carried away and built my own public API to the Trove newspaper database.

Unofficial Trove newspapers API

I think it’s important to note that the tools I developed were guided by the types of questions I wanted to ask. While we should welcome APIs and celebrate their possibilities, we should also remain critical. APIs are interfaces, they too embed power relations. Every API has an argument. What questions do they let us ask? What questions do they prevent us from asking?

Even as we move from the age of lumbering, slow-witted data silos into the rapidly-evolving realms of Linked Open Data, we have to constantly question the models we make of the world. Ontologies and vocabularies are culturally determined and historically specific. Yes, they too are interfaces, complete with their own distributions of power and authority. But we can revisit and change them. And we can relate our new models to our old models, capturing complex, long-term shifts in the way we think about the world. That’s incredibly exciting.

All of this hacking, harvesting, questioning, enriching and meaning-making makes me think about the possibilities of grassroots leadership. Online technologies enable people to take cultural institutions into unexpected realms. They can build their own interfaces, ask their own questions, determine their own needs — they can point the way instead of simply waiting to be served.

You might wonder what the National Library of Australia thinks of my various scrapers and harvesters. I can’t speak for them, but I can say that they’ve awarded me a fellowship to explore further the possibilities of text-mining in their newspaper database.

The idea of grassroots leadership brings me back to the title of this talk — ‘It’s all about the stuff’. It seems to me that we tend to model the interactions between cultural institutions and the public as transactions. The public are ‘clients’, ‘patrons’, ‘users’ or ‘visitors’. But the sorts of things I’ve been talking about today give us a chance to put the collections themselves squarely at the centre of our thoughts and actions. Instead of concentrating on the relationship between the institution and the public, we can can focus on the relationship we both have with the collections.

It’s all about the stuff.

It’s all about the respect and responsibility we both have for our collections.

It’s all about the respect and responsibility we both have for people like this.

Entering the web of data

Keynote delivered at the annual conference of the Australia and New Zealand Society of Indexers, 14 September 2011.


This is me.

Today, Wednesday, 14 September 2011, I’m honoured to be able to join you here in the luxurious surrounds of the Brighton Savoy Hotel for the ‘Indexing See Change‘ conference. This is an event, a moment in history; we can pinpoint ourselves, this gathering, both in time and in space.

If we do that, if we move outside the moment and position ourselves on a timeline or a map, interesting things start to happen. Connections emerge.

Here we are at number 150, The Esplanade, in Brighton. A bit over a kilometre away is the stately villa, Kamesburgh. For many years Kamesburgh was also known as the Anzac Hostel — a refuge for permanently-incapacitated World War One veterans.

The Anzac Hostel opened on 5 July 1919. Here it is draped in its patriotic finery, from the collections of the Australian War Memorial. According to the caption, the Anzac Hostel was ‘a home, not an institute’.

Also amongst the War Memorial’s holdings is a wheeled bed that was used at the hostel. This particular bed was apparently occupied by one man, Albert Ward, for forty-three years.

Death notice for Alexander Kelley. Argus, 29 January 1944.

It was probably in a bed just like this that Alexander Dewar Kelley passed away on 27 January 1944. Alexander Kelley was cremated, and his remains interred amongst the roses at what is now called the Springvale Botanical Cemetery. Not far from my own grandparents.

Alexander Kelley spent close to half his life in the Anzac Hostel. Like many young men, he bravely answered his nation’s call to arms, but returned from war much changed. We can follow Alex’s war through his service record, easily-accessible through the website ‘Mapping Our Anzacs‘.

Alex was a coach painter who enlisted in the AIF in January 1916. Within a year he was in France. In May 1917 he suffered a gunshot wound to the head, but was able to rejoin his unit in August. Less than a month later though, he was wounded again, this time more severely. For Alex the war was over, and he was shipped back to Australia in May 1918.

‘Mapping Our Anzacs’ includes a scrapbook feature through which visitors to the site can attach notes or photographs to a service record. Amongst the the many thousands of postings is a fragment from a diary, found tucked inside the bible of Alexander Kelley’s mother. The diary entry reads simply: ‘Alex arrived from Front. Wet day. Saw him at “Caulfield”.’

Alex had survived and had returned to his family. This was a day to remember. But there was sadness too, for Alex was not the same young man who had left for the battlefields of Europe. In the diary fragment, ‘Caulfield’ is enclosed in inverted commas, indicating perhaps that the reunion took place, not in the suburb, but in the Caulfield rehabilitation hospital. Alexander Kelley was wounded in the face, hands and legs. He was left blind in both eyes and his right leg was amputated. He would live the remainder of his life a little over a kilometre away from here at the Anzac Hostel.

This is just one story. There are over 375,000 World War One service records held by the National Archives of Australia. How can we hope to understand a number like that? How can we hope to imagine the war’s impact on families, on communities?

‘Mapping Our Anzacs’ uses familiar Google maps to display the places of birth and enlistment recorded in many of those service records. But technical limitations make it impossible to display all the places at once. You can, however, take the same data and open it in Google Earth. If you then zoom in on Victoria, you see something like this.

Mapping Our Anzacs data viewed in Google Earth.

Each marker represents a place where a service person was born or enlisted. It’s impossible to read, of course, but that’s the point. There is so little blank space. As you zoom further, more markers appear, more place names resolve. It’s simple, but it’s powerful. They came from everywhere. From the smallest village to the biggest city; nowhere was untouched.

The ‘Mapping Our Anzacs’ scrapbook offers another perspective. It’s possible to extract the images posted to the scrapbook and present them on a 3D wall. Amidst an assortment of memorabilia, there are faces. Not places, or records — this is a wall of people.

Mapping Our Anzacs Scrapbook photos viewed through CoolIris

It’s worth noting too that like the markers on the maps, these faces link back to the actual service records. So they’re not just a new way of seeing the collection, they’re a new way of exploring it.

But the records don’t stand in isolation, they themselves have a context. A couple of years ago, Mitchell Whitelaw from the University of Canberra, undertook a project called ‘The Visible Archive‘ to investigate ways of visualising the holdings of the National Archives of Australia. Have you ever wondered what 360km worth of records looks like?

The collections of the NAA visualised by Mitchell's Series Browser.

This represents the holdings of the National Archives. Files within the archives are organised into series, and each square in this image represents a single series — there are about 60,000 of them. Naturally the size of the square gives an indication of the size of the series itself. It’s a fascinating and strangely beautiful picture.

It’s easy enough to pick out the World War One service records — Series B2455. In the interactive version of Mitchell’s series browser you can click on a box and display links between series, as well as other series created by the same government agency. Again, it’s not just a way of seeing the collection, but a means of exploring and interpreting it. As Mitchell says:

Visualisation enables us to literally show everything, to display large volumes of data in a way that reveals patterns and communicates context, but also provides access to the fine grain of individual elements.

But we can also employ such techniques to ask new kinds of questions. Can you imagine how Alexander Kelley and the other inhabitants of the Anzac Hostel must have felt in 1939? They had lost so much in the Great War, the ‘war to end all wars’, and yet within their own lifetime it was all happening again. More young men were answering the call, more lives were going to be destroyed.

There must have been a dreadful, disheartening moment when Australians realised that the Great War was not an end, but a beginning — the first in a series of devastating global conflicts. At some point the ‘Great War’ became the ‘First World War’, but when?

When did the 'Great War' become the 'First World War'?


This is one possible answer. This graph draws its data from the 50 million or so digitised newspaper articles in Trove, the National Library of Australia’s discovery service. It shows the proportion of newspaper articles that included the phrase ‘the great war’ compared to the proportion containing ‘the first world war’ (and variations thereof). The lines cross late in 1941. With German victories in Europe and Africa, the opening of the Eastern Front and the Japanese attack on Pearl Harbour, 1941 makes sense.

What is perhaps more intriguing is the dramatic peak in the occurrence of ‘the great war’ in 1939. It’s no surprise that the looming threat of a new conflict would provoke comment and comparisons, but it does make you wonder about the context of those discussions and how they might have changed as the reality of war edged closer.

To start exploring this I’ve harvested the content of the 6,600 articles from 1939 that included the phrase ‘the great war’. Using an online text analysis service called VoyeurTools I can quickly generate a picture of their contents.

This simple visualisation shows us the relative frequencies of words within the articles. It doesn’t reveal any great mysteries, but it does suggest some possibilities for further prodding. The prevalence of ‘time’ and ‘new’, for example — might these help us understand the shift in perspective from one war to the next? We can follow this up by browsing the different contexts in which the words were used.

But what actually is it that we’re actually searching? We know that Trove includes newspapers from 1803 to 1954, but if we’re really going to analyse shifting words and ideas it’s important to have a clear picture of the sources of those words.

Something like this perhaps. This graph shows the holdings of the Trove newspaper database on 4 August 2011, organised by state. You can see, for example, that if you’re searching on a topic between the 1920s and 1940s you’re probably likely to get more results from Queensland than anywhere else.

So starting from our location here, today, we can make connections across time and space. We can pull back and look at the big picture, or dive in and examine the fabric of a single life. Through the web we can build and explore a rich and complex contextual network.


It’s an exciting time to be a cultural data hacker. We now have a growing range of tools and technologies available for extracting interesting data from a wide variety of sources, both structured and unstructured.

The ‘Visible Archive’ project started with well-structured data, courtesy of Peter Scott, the developer of the Series System — the descriptive framework used by many Australian archives. But we’re rarely so lucky.

Even when the data starts off in nicely-organised fields in a database there’s no guarantee that that’s how it’s going to be delivered to our web browser. In order to extract the data from my Trove graphs, for example, I had to write a little program called a ‘screen scraper‘ to identify and save the important metadata elements from the raw web page itself.

Where there are no subject keywords we can infer them using techniques such as topic modelling. Where there are no access points we can identify people, organisations, places and events using special tools developed for named entity extraction. Where there are no common identifiers across datasets we can employ record linkage technologies to find possible connections.

We can count words, we can identify parts of speech, we can formulate a measure of the similarity of any two pieces of text. Once we have some useful data we can manipulate and enrich it. Place names can be geolocated — you simply send your place name off to a web service and get back its latitude and longitude.

Increasingly these sorts of tools are becoming accessible to anyone. For historians they offer a means of wrestling with rapidly-growing bulk of source material that is becoming available in digital form. How do you make use of 5 million digitised books, 50 million newspaper articles or the complete archive of every public message ever sent on Twitter?

The digital historian Dan Cohen has noted:

These computational methods which allow us to find patterns, determine relationships, categorize documents, and extract information from massive corpuses, will form the basis for new tools for research in the humanities and other disciplines in the coming decade.

Dan is involved in a number of interesting projects investigating the possibilities of these techniques — often grouped together under the heading ‘text mining’. One of these projects, ‘With Criminal Intent‘, is looking to see what patterns can be drawn out of the digitised proceedings of criminal trials held at the Old Bailey from 1645 to 1913. That’s 197,745 trials, in case you were wondering.

Here’s one of their visualisations showing how the length of trials varies over time. Much to the surprise of the research team, this graph suggests a dramatic shift in legal practice around 1825 — defendants started pleading guilty!

A visualisation by the With Criminal Intent project showing changing trial lengths.

Rather than falter under the growing weight of digital sources, these technologies can actually thrive. The more raw material available, the more chance there is to observe and track new patterns. As digitisation continues apace will we ever reach the point when history can simply be read from a graph?

There are some researchers at Harvard who seem to think that’s where we’re heading. Borrowing liberally from the store of scientific metaphors they have staked out the new field of ‘culturomics‘. By mining massive digital resources, like Google’s scanned books, they hope to map the ‘cultural genome’ that would enable us to follow the evolution of language and culture.

But there’s something quite barren in this ambition. I prefer the vision of digital humanist Stephen Ramsay, who commented in regard to the ‘With Criminal Intent’ project:

The Old Bailey, like the Naked City, has eight million stories. Accessing those stories involves understanding trial length, numbers of instances of poisoning, and rates of bigamy. But being stories, they find their more salient expression in the weightier motifs of the human condition: justice, revenge, dishonor, loss, trial. This is what the humanities are about. This is the only reason for an historian to fire up Mathematica or for a student trained in French literature to get into Java.

Ultimately it’s the stories that nourish, anger, inspire and depress us. The closely-packed map of places recorded in World War I service records is so powerful because we know that under each marker are men, women, families, communities — each with their own story. These new technologies offer new perspectives, they raise new questions, and they challenge us with new contexts to explore and understand. But there is still space for stories and perhaps we can use them to give our stories new life and depth.


This is another World War One service record. It belongs to Charlie Allen. Charlie enlisted three times in the AIF and was discharged on medical grounds each time. It seems he had a problem with his ankle.

Charlie’s service record notes a tattoo, proclaiming his love for ‘Maud Gordon’. He married Maud in Sydney in 1917 and had two daughters soon after.

Charlie survived the war without further injury, but was not so lucky in peace. On 11 March 1938, Charlie was crushed to death between two railway cars. The accident happened at the Bunnerong Power Station, only a short distance from his home in Matraville. He was buried nearby in the Botany Cemetery.

We also know quite a bit about Charlie’s early life. Why? Because Charlie’s father was Chinese and he was therefore categorised as a ‘half-caste’, as someone who was not white, and therefore fell under the restrictions imposed by the White Australia Policy.

Charlie was born in Sydney in 1896. His mother was Frances Allen (sometime sweet shop owner and brothel keeper), his father Charlie Gum (a buyer for Wing On company). Charlie was raised by his mother, but in 1909, at the age of 13, he was taken to China by his father.

NAA: ST84/1, 1909/22/41-50

This certificate granted Charlie an exemption to the Dictation Test. Without it, he may not have been allowed back into the country.

Every time one of many thousands of non-Europeans resident in Australia sought to travel overseas and return home again they needed one of these certificates.

Charlie’s father returned to Sydney, leaving him in China. He lived with relatives in the town of Shekki (inland from Hong Kong). Charlie was naturally homesick, but had no means of getting back to Australia. He wrote to his mother in 1910:

Do try and bring me home every minute I think of you and long for a piece of bread and butter this tucker is not doing me well.

His mother wrote to the Prime Minister Billy Hughes in an attempt to enlist government help but to no avail. Charlie finally returned to Australia in 1915.

Despite this experience, Charlie visited China again in 1922 for 7 months. Once again carrying papers to grant him re-entry to the country of his birth.

These fragments of Charlie’s life have been assembled by my partner, Kate Bagnall, a historian of Chinese-Australia. They are remarkable, and yet not so, because there are many thousands of stories like Charlie’s contained within the voluminous records generated by the administration of the White Australia Policy.

We’re all of course familiar with the general outlines of the White Australia Policy, and the way it underpinned conceptions of Australia as a nation in the first half of the 20th century.

But what we sometimes forget is that it was also a massive bureaucratic exercise.

Forms and certificates were printed, issued, used and filed. Regulations were modified, guidelines were distributed and administering officers were managed and advised. Individual cases were reviewed, policy was changed and new forms and certificates were printed, issued, used and filed…

Much of this system is now preserved in the National Archives.

You can get a idea of the range of material available from a case study Kate has prepared focusing on the efforts of Poon Gooey, a successful businessman in Horsham, to keep his wife and family in Australia.

If we look again at Charlie’s certificate from 1909 we can see that it contains a lot of interesting structured data:

  • name
  • place of birth
  • age
  • height
  • destination
  • date of departure
  • name of ship

We estimate that there are probably about 50,000 of these forms remaining in the Archives, and then there’s case files and a variety of other government documents.

Wouldn’t it be great if we could extract this structured data. If we could piece together the slivers of identity that remain within the Archives and give people back their lives.

This is the dream of Invisible Australians, a project Kate and I are trying to turn into a reality. Our aim is to build systems that will enable this data to be extracted, aggregated, shared and connected — whether to a family tree, a cemetery record, or another document in another archive.

Imagine being able to navigate the network of lives, families and relationships. To follow their journeys, to share their tragedies, to celebrate their small victories against a repressive system.

Imagine being able to watch them age.


We tend to assume that new technologies require us to change, to adapt. But sometimes they can take advantage of our strengths. Mitchell Whitelaw is interested in finding out what happens when you take large cultural datasets and try to ‘show everything’. Such an approach, he suggests, takes advantage of the raw processing power of computers, while giving us space to do what we’re good at — finding patterns, making connections, crafting meanings.

The History Wall tries to create a similar sort of space. The History Wall brings together material from a range of different sources — newspaper articles from Trove, biographies from the Australian Dictionary of Biography, records from a database of NSW convicts, population statistics, collection items from the National Museum of Australia — you can pretty much plug anything in as long as it has a date attached to it.

Irish History Wall

For a particular year, the Wall retrieves a random sample from the available sources, jumbles everything up and then throws it onto the screen. As a result, no two views of the Wall are ever quite the same. This is not a traditional exhibition. There is no curator controlling the content or designing the structure. It’s ephemeral, it’s serendipitous — instead of relying on an authorial voice to smooth over the gaps and transitions, it leaves open the cracks and allows new contexts to seep in and around each item.

As the pioneering digital historian Edward Ayers noted:

even isolated and inert pieces of evidence — a list, a letter, a map, a picture — can assume new and unimagined meanings when placed in juxtaposition with other fragments.

This is not an absence of narrative, but an opportunity for narration. Edward Ayers suggests that we’re actually quite comfortable filling in blanks and untwisting timelines:

Humans, presented with pieces of information about people, put things into the form of a story. They need not be simple stories, for we know how to deal with unexplained lapses of time, flashbacks, and overlapping narratives. We know how to imagine, infer, things happening at the same time in different places. Film and television train all of us at early ages to weave strands of narrative out of intentional (if carefully constructed) confusion and to take pleasure in that weaving.

And so I can show you a death notice, or a certificate and you will take those fragments, those isolated data points and you will construct a story — you will see the person behind them, you will imagine their life. It’s what we do. We’re good at it.

Computers on the other hand will just see data.

In her ode in praise of humanities data, digital humanist Amanda French wonders whether we always need to crunch our data into abstract, pliable forms:

What I wonder is whether instead we can begin with the data, or with a datum, and simply watch for what it may tell us, even if what it tells us is simply a story.

Yes we can. And we should teach computers how to do it as well. Not because we want them to take over. Not because they can necessarily do it faster or better. But because they can help us share, preserve and connect those stories.

Let’s think again about the array of documents that Kate has assembled to piece together the story of Charles Allen. How can you share this sort of material? Typically you’d ‘write it up’. You’d capture the story behind the data and commit it to words. The documents would then become evidence — points of connection between your text and the historical record.

So in order to share the meanings of these documents we remove them from the context of the person’s life and marshal them as allies to proclaim the authenticity of our rendering. Wouldn’t it be better if we could tell the story, but maintain within our texts the direct connections between sources and subject?

What we need is a data framework that sits beneath the text, identifying people, dates and places, and defining relationships between them and our documentary sources. A framework that computers could understand and interpret, so that if they saw something they knew was a placename they could head off and look for other people associated with that place. Instead of just presenting our research we’d be creating a whole series of points of connection, discovery and aggregation.

Sounds a bit far-fetched? Well it’s not. We have it already — it’s called the Semantic Web.

The Semantic Web exposes the structures that are implicit in our web pages and our texts in ways that computers can understand. The Linked Data movement takes the basic ideas of the Semantic Web and turns them into a collaborative activity. You share vocabularies, so that other people (and computers) know when you’re talking about the same sorts of things. You share identifiers, so that other people (and computers) know that you’re talking about a specific person, place, object or whatever.

Linked Data is Storytelling 101 for computers. It doesn’t have the full richness, complexity and nuance that we invest in our narratives, but it does at least help computers to fit all the bits together in meaningful ways. And if we talk nice to them, then they can apply their newly-acquired interpretative skills to the things that they’re already good at — like searching, aggregating, or generating the sorts of big pictures that enable us to explore the contexts of our stories.

This is why we’ve always imagined Invisible Australians to be something more than an online database. We want to provide points of connection that other people can build into their own stories. But to do that we have to pay attention to things like vocabulary management and authority control, we have to construct web addresses that are not going to break every time we upgrade our software. We have to think about the sorts of things we’re talking about — not just people, but government agencies, legislation, certificates, and correspondence. How do we describe these entities and what sorts of relationships do they have?

And of course we need to expose all these structures so that we can say, these things are people, these are events, these are places and these are documents.

Or perhaps, to introduce Alexander Kelley.

Or remember Charles Allen.


You might be wondering why we don’t just leave it all to the computers themselves. Didn’t I just talk about all the exciting new tools and techniques that enable us to analyse the structures of texts? Perhaps we should just wait for the Culturomics guys to solve all the problems.

But who defines the problems?

Our postmodern sensibilities encourage a suspicion of neutrality. Labels like ‘the new museology’ or Archives 2.0 reflect an awareness that the way we describe and arrange our collections is itself culturally-determined. It’s not just a matter of what our descriptive systems show, but what they hide.

Tim Hitchcock, another member of the ‘With Criminal Intent’ team, has described how online technologies can change the way we access archives. Instead of being forced to navigate the hierarchical structures that archives impose on records, which in turn tend to reflect the workings of the institutions that created the records, we can directly find the people whose lives were regulated, influenced, shaped or controlled by the policies of those institutions.

Instead of merely hearing ‘the institutional voice… in all its stentorian splendour’, he says, we can listen in to ‘the quieter tones uttered by the individual’.

This reminds us that search boxes, along with other digital tools, themselves embody arguments. There are assumptions built into their code about what is relevant, what is significant, what is necessary.

We can build our own tools of course, and we can critique other people’s algorithms. But what if we just want to collect and share stories?

Linked Data gives us a way to present an alternative to Google’s version of the world. We can argue back against the search engines, defining our own criteria for relevance, and building our own discovery networks.

Changing the way we access resources changes the sorts of stories we can tell. Tim Hitchcock asks:

What happens when institutions and archives are ‘decentred’ in favour of the individual? What changes when we examine the world through the collected fragments of knowledge that we can recover about a single person, reorganised as a biographical narrative, rather than as part of an archival system?

Perhaps the invisible become visible.

Liberating lives: invisible Australians and biographical networks

Charlie Allen's palm print
This palm print belongs to a 12-year-old boy called Charlie Allen.

Charlie was born in Sydney in 1896.

His mother was Frances Allen (sometime sweet shop owner and brothel keeper), his father Charlie Gum (a buyer for Wing On company).

Charlie was raised by his mother, but in 1909, at the age of 13, he was taken to China by his father.

His father returned to Sydney, leaving Charlie in China. He lived with relatives in the town of Shekki (inland from Hong Kong) for 6 years.

Charlie was homesick, but had no means of getting back to Australia. His mother attempted to enlist government help but to no avail. Charlie finally returned in 1915.

The following year he enlisted in First AIF (well actually he enlisted three times, and was discharged as medically unfit each time).

Charlie married in Sydney in 1917 and had two daughters soon after. He returned to China in 1922 for 7 months.

Charlie Allen died in 1938 as the result of an industrial accident. He was 41.

How do we know all this about Charlie Allen?

We know this because there are fragments of Charlie’s life scattered throughout the holdings of the National Archives of Australia.

The CEDT from 1909 when he left Australia with his father:

Charles Allen 1909 - CEDT front

NAA: ST84/1, 1909/22/41-50


A letter from his mother to Prime Minister Billy Hughes, seeking help to return Charlie to Australia:
Letter to Billy Highes from Charlie's mother.

NAA: A1, 1911/13854


His WWI service record:
Charles Allen's WWI attestation form

NAA: B2455, ALLEN C A


An identity form relating to his trip to China in 1922:

NAA: SP42/1, C1922/4449


But of course Charlie is not alone in the archives.

Charlie’s father was Chinese, he was therefore categorised as a ‘half-caste’, as someone who was not white, and fell under the restrictions imposed by the White Australia Policy.

The certificate from 1909 granted Charlie an exemption to the Dictation Test. Without it, he may not have been allowed back into the country.

Every time one of many thousands of non-Europeans resident in Australia sought to travel overseas and return home again they needed one of these certificates.

We’re all of course familiar with the general outlines of the White Australia Policy, and the way it underpinned conceptions of Australia as a nation in the first half of the 20th century.

But what we sometimes forget is that it was also a massive bureaucratic exercise.

Forms and certificates were printed, issued, used and filed. Regulations were modified, guidelines were distributed and administering officers were managed and advised. Individual cases were reviewed, policy was changed and new forms and certificates were printed, issued, used and filed…

For example, between 1901 and 1911, 400 circulars were issued to port officers about immigration restriction. The confidential manual on immigration restriction grew from one page in 1902 to more than 200 in 1912.

Much of this system is now preserved in the National Archives.

For the years between 1902 and 1948 there remain:

  • More than 50,000 CEDTs
  • 90 shelf metres of records
  • 15,000 case files

And within those many thousands of files are the scattered fragments of lives such as Charlie’s — lives that were controlled, monitored and documented in a vain attempt to make Australia ‘white’.

We’ve already seen today some wonderful examples of how these fragments, these slivers of existence, can be found, extracted, aggregated and displayed. But I think it’s worth considering for a moment what happens when we do this.

The historian Tim Hitchcock, behind projects such as the Old Bailey Online and London Lives, has reflected on the impact of digitisation on our access to archives. Archives, he notes, tend to reflect the assumptions and practices of the institutions that created them.

But by providing new ways into these records systems, technology can undermine the power relations that persist within their structures.

‘What changes’, asks Tim Hitchcock, ‘when we examine the world through the collected fragments of knowledge that we can recover about a single person, reorganised as a biographical narrative, rather than as part of an archival system?’

I don’t know, but I think we should find out, don’t you?

**********

I hope you’ve all collected a mini card. These themselves provide a little glimpse at the real face of White Australia and I’d invite you all to head over to the National Archives website, do battle with the monster that is RecordSearch, and look up the file references that are on each card.

The cards are part of a project that Kate Bagnall and I are trying to develop — Invisible Australians.

I should note too that the cards, and most of the examples I’m showing you here today are the product of Kate’s long and detailed research into Chinese-Australian families. In modern project management parlance, Kate is the domain expert, while I am merely the technical resource.

If we look again at one of the CEDTs, we can see that there’s a lot of useful structured data:

  • name
  • place of birth
  • age
  • height
  • destination
  • date of departure
  • name of ship

Invisible Australians has the modest aim of extracting this data from the 50,000+ forms in the National Archives. But of course that’s just the start, because each person might have used a number of certificates — so then it’s a matter of matching these identities.

Invisible Australians

http://invisibleaustralians.org

And then there are a range of other related forms, not to mention case files, alien registration documents, naturalisation applications…

Obviously we can’t do it alone. We’ll be creating a crowdsourcing tool to extract and link the data.

It’s ridiculously ambitious, totally unfunded and is likely to take over our lives.

Is it worth it?

Imagine being able to navigate the network of lives, families and relationships. To follow their journeys, to share their tragedies, to celebrate their small victories against a repressive system.

Imagine being able to watch them age.

Pauline Ah Hee and Shadee Khan

Is it worth it? We think so.

**********

For Tim Hitchcock technology opens up the possibility of writing a new history from below, exploring how the poor, the marginalised and the powerless navigated the institutions of the modern state. But it’s not just about search engines and databases. He talks about making ‘best use of the technology of emotions and representation — how you use words and pictures and a story to impact, not just on what people think, but what they see in their mind’s eye’.

In this project, the photos matter. I hope the irony in our project title is obvious.

Some of the faces of Invisible Australia

This is the real face of White Australia.

The photos remind us that the project is not just about shifting data around — these are lives, these are people.

But this brings its own challenge, for if we are seeking to liberate these lives from the fragmentation and obscurity of bureaucratic systems then we should be asking what are we liberating them into?

A database?

This is not just an exercise in data creation and management. We also have to think carefully and creatively about issues of representation, access and discovery.

We have to give these lives back their freedom to associate, to have relationships, to make connections.

We need to embed these lives in a variety of contexts and combinations. To make room for serendipity, celebration, sadness, and yes, even play.

We need to bring these lives into a rich and ongoing conversation with the world.

But how?

**********

I’ve been working on a little experiment for the National Museum of Australia called The History Wall. What the History Wall does is quite simple, it pulls together data on the fly from a variety of sources including People Australia, the Australian Dictionary of Biography, the National Library’s newspapers project, historical population data from the Bureau of Statistics, photos from the Flickr accounts of the PowerHouse Museum and the National Archives, and the collection database of the National Museum itself. It chooses randomly from all this stuff, throws the results up into the air and then displays them however they happen to fall. No two views are ever quite the same.

The History Wall

http://defining.net.au/wall/

It’s something more than a timeline. To me it’s more like a celebration of context and serendipity. There’s a richness to it, a sense of discovery and fun, but there’s also fragility — next time you look it might be gone.

It’s a bit like history itself.

It’s a bit like the world.

How do we create spaces for our data to merge and mingle? How do we encourage the development of new contexts and connections?

I think the first thing we have to do is stop thinking about databases and dictionaries, registers and encyclopaedias. Don’t get me wrong, I’m not being critical of the wonderful projects we’ve seen today. I just think we can use all this work better if we stop thinking about individual resources and start developing on a web scale, on a global scale.

Yes, we have the technology. Time today has spared you from a detailed discourse on the Semantic Web, but I do want to focus on one aspect.

You may have heard of Linked Data, it’s a set of guidelines to help you publish your data to the Semantic Web. There are only four basic principles and I’m only going to talk about one of them. It’s one of those deceptively simple things. You look at it and think, ‘yeah, ok’, but before too long it’s starting to turn your brain inside out.

Use URLs to identify things in the real world.

Yeah, ok…

You know what URLs are, web addresses, the things you type in your browser’s location field.

And hopefully you know what things in the real world are: people, places, objects, events, ideas…

Now you may have detected a problem here, because no matter how many times you click the refresh button, your web browser is not going to be able to use such a URL to magically deliver you the real world thing.

Well, unless you’re on eBay.

Fortunately, the Linked Data guidelines provide for a bit of technical trickery that allow your browser to retrieve not the real world thing, but some information about that thing — perhaps in the form of a web page.

Why bother?

Names are powerful.

We share and use names to talk about things. Computers are the same. If we use URLs to identify things in the real world, then computers can start talking about them.

We can define and explore real-world relationships in an online environment. We can create rich, meaningful linkages across databases, across disciplines, across the world.

We can start building and thinking on a web scale.

**********

Thanks to the People Australia project, I can confidently claim that this is me:

http://nla.gov.au/nla.party-479364#foaf:Person

I keep meaning to get it on a t-shirt.

The most exciting thing about People Australia is not the EAC records or the aggregation of resources — it’s the identifiers, because they enable us to say things about people anywhere on the web that computers can understand and relate back to a specific real world entity — a person.

You can start doing it now with Wragge’s Identity Browser.

Wragge's Identity Browser

http://wraggelabs.com/identities/

This is a little tool I built using the People Australia API. It makes it easy to find identifiers for people and organisations, and it supplies you with some code that you can drop into a blog post or web page that will tell a computer that a name relates to a thing called a ‘person’ , that this person’s name has a certain standard form, and that this person can be uniquely identified by People Australia.

Even if you don’t publish a website or a blog, you can use People Australia identifiers to build semantic linkages. Wragge’s Identity Browser also creates machine tags for you. Machine tags are like normal tags but with built in semantics. When coupled with identifiers they enable you to do some pretty powerful things.

You could for example use machine tags in Flickr to tell computers that a certain photo depicts a person uniquely identified by People Australia. In fact, people have been doing just that.

Flickr Machine Tag Challenge

http://wraggelabs.com/fmtc/

The Flickr Machine Tag Challenge is a sort of scoreboard that I built to encourage people to start adding People Australia enriched machine tags to photos. More than 1200 tags have been added to over 1000 photos. Feel free to join in!

The point is that the technologies already exist to enable us to build web scale biographical resources. Not dictionaries or databases as we know them, but networks capable of constant expansion, elaboration, and cooperation.

What we need are more tools to make it simple, recipes to make it obvious, examples and applications to make it popular, and leadership to make it all seem possible.

**********

Of course most of the lives we hope to liberate through Invisible Australians will not be represented in People Australia.

Not yet.

But Invisible Australians will offer a point of aggregation and disambiguation that will enable our people to find their way from the bureaucratic recesses of the White Australia Policy to a place on the national stage.

And we will encourage others to do likewise. Basil can’t do all the work. The centralised system has to be fed through centres of aggregation and collaboration.

Similarly, there are many great resources already out there relating to Chinese-Australians. There are hordes of family and local historians compiling and publishing biographical data. We want to identify people in these resources and link to them.

We want to publish up to People Australia and link down to a single headstone in a lonely country cemetery.

But to do this we need to help people make their resources linkable. To help them create persistent, re-usable URLs, and expose their data in standard formats. To create Linked Data, even if they have no particular interest in the Semantic Web.

Invisible Australians

http://invisibleaustralians.org/

Invisible Australians is not just about extracting data from archives. It’s also about working with others to build capacities and demonstrate possibilities.

It’s ridiculously ambitious, totally unfunded and is likely to take over our lives.

Is it worth it?

We think so.
