Oceania

I am really excited to have begun my latest project: a Linked Open Data service for online cultural heritage from New Zealand and Australia, and eventually, I hope, from our other neighbours. I have called the service “oceania.digital

The big idea of oceania.digital is to pull together threads from a number of different “cultural” data sources and weave them together into a single web of data which people can use to tell a huge number of stories.

There are a number of different aspects to the project, and a corresponding number of stages to go through… Continue reading Oceania

Australian Society of Archivists 2016 conference #asalinks

Last week I participated in the 2016 conference of the Australian Society of Archivists, in Parramatta.

I was very impressed by the programme and the discussion. I thought I’d jot down a few notes here about just a few of the presentations that were most closely related to my own work. The presentations were all recorded, and as the ASA’s YouTube channel is updated with newly edited videos, I’ll be editing this post to include those videos.

Linked Open Data Visualisation at #GLAMVR16

On Thursday last week I flew to Perth, in Western Australia, to speak at an event at Curtin University on visualisation of cultural heritage. Erik Champion, Professor of Cultural Visualisation, who organised the event, had asked me to talk about digital heritage collections and Linked Open Data (“LOD”).

The one-day event was entitled “GLAM VR: talks on Digital heritage, scholarly making & experiential media”, and combined presentations and workshops on cultural heritage data (GLAM = Galleries, Libraries, Archives, and Museums) with advanced visualisation technology (VR = Virtual Reality).

The venue was the Curtin HIVE (Hub for Immersive Visualisation and eResearch); a really impressive visualisation facility at Curtin University, with huge screens and panoramic and 3d displays.

There were about 50 people in attendance, and there would have been over a dozen different presenters, covering a lot of different topics, though with common threads linking them together. I really enjoyed the experience, and learned a lot. I won’t go into the detail of the other presentations, here, but quite a few people were live-tweeting, and I’ve collected most of the Twitter stream from the day into a Storify story, which is well worth a read and following up.

Visualizing Government Archives through Linked Data

Tonight I’m knocking back a gin and tonic to celebrate finishing a piece of software development for my client the Public Record Office Victoria; the archives of the government of the Australian state of Victoria.

The work, which will go live in a couple of weeks, was an update to a browser-based visualization tool which we first set up last year. In response to user testing, we made some changes to improve the visualization’s usability. It certainly looks a lot clearer than it did, and the addition of some online help makes it a bit more accessible for first-time users.

The visualization now looks like this (here showing the entire dataset, unfiltered, which is not actually that useful, though it is quite pretty):

Bridging the conceptual gap: Museum Victoria’s collections API and the CIDOC Conceptual Reference Model

This is the third in a series of posts about an experimental Linked Open Data (LOD) publication based on the web API of Museum Victoria.

The first post gave an introduction and overview of the architecture of the publication software, and the second dealt quite specifically with how names and identifiers work in the LOD publication software.

In this post I’ll cover how the publication software takes the data published by Museum Victoria’s API and reshapes it to fit a common conceptual model for museum data, the “Conceptual Reference Model” published by the documentation committee of the Internal Council of Museums. I’m not going to exhaustively describe the translation process (you can read the source code if you want the full story), but I’ll include examples to illustrate the typical issues that arise in such a translation.

Names in the Museum

My last blog post described an experimental Linked Open Data service I created, underpinned by Museum Victoria’s collection API. Mainly, I described the LOD service’s general framework, and explained how it worked in terms of data flow.

To recap briefly, the LOD service receives a request from a browser and in turn translates that request into one or more requests to the Museum Victoria API, interprets the result in terms of the CIDOC CRM, and returns the result to the browser. The LOD service does not have any data storage of its own; it’s purely an intermediary or proxy, like one of those real-time interpreters at the United Nations. I call this technique a “Linked Data proxy”.

I have a couple more blog posts to write about the experience. In this post, I’m going to write about how the Linked Data proxy deals with the issue of naming the various things which the Museum’s database contains.

Linked Open Data built from a custom web API

I’ve spent a bit of time just recently poking at the new Web API of Museum Victoria Collections, and making a Linked Open Data service based on their API.

I’m writing this up as an example of one way — a relatively easy way — to publish Linked Data off the back of some existing API. I hope that some other libraries, archives, and museums with their own API will adopt this approach and start publishing their data in a standard Linked Data style, so it can be linked up with the wider web of data.
