The Unlock development team recently attended the Dev8D: JISC Developer Days conference at University College London. The format of the event is fairly loose, with multiple sessions in parallel and the programme created dynamically as the 4 days progressed. Delegates are encouraged to use their feet to seek out what interests them! The idea is simple: developers, mainly (but not exclusively) from academic organisations come together to share ideas, work together and strengthen professional and social connections.
A series of back-to-back 15 minute ‘lightning talks’ ran throughout the conference, I delivered two – describing EDINA’s Unlock services and showing users how to get started with the Unlock Places APIs. Discussions after the talk focused on the question of open sourcing and the licensing of Unlock Places software generally – and what future open gazetteer data sources we plan to include.
Throughout Dev8D, several competitions or ‘bounties’ were held around different themes. In our competition, delegates had the chance to win a £200 Amazon voucher by entering a prototype application making use of the Unlock Places API. The most innovative and useful application wins!
I gave a quick announcement at the start of the week to discuss the competition, how to get started using the API and then demonstrated a mobile client for the Unlock Places gazetteer as an example of the sort of competition entry we were looking for. This application makes use of the new HTML5 web database functionality – enabling users to download and store Unlock’s feature data offline on a mobile device. Here’s some of the entries:
Marcus Ramsden from Southampton University created a plugin for EPrints, the open access respository software. Using the Unlock Text geoparser, ‘GeoPrints’ extracts locations from documents uploaded to EPrints then provides a mechanism to browse EPrint documents using maps.
Aidan Slingsby from City University, entered some beautiful work displaying point data (in this case a gazetteer of British placenames) shown as as tag-maps, density estimation surfaces and chi surfaces rather than the usual map-pins! The data was based on GeoNames data accessed through the Unlock Places API.
And the winner was… Duncan Davidson from Informatics Ventures, University of Edinburgh. He used the Unlock Places APIs together with Yahoo Pipes to present data on new start-ups and projects around Scotland. Enabling the conversion of data containing local council names into footprints, Unlock Places allowed the data to be mapped using KML and Google Maps, enabling his users to navigate around the data using maps – and search the data using spatial constraints.
Some other interesting items at Dev8D…
Hugh Glaser from the University of Southampton discussed how sameAs.org works to establish linkage between datasets by managing multiple URIs for Linked Data without an authority. Hugh demonstrated using sameAs.org to locate co-references between different data sets.
Mendeley is a research network built around the same principle as last.fm. Jan Reichelt and Ben Dowling discussed how by tracking, sharing and organising journal/article history, Mendeley is designed to help users to discover and keep in touch with similarly minded researchers. I heard of Mendeley last year and was surprised by the large (and rapidly increasing) user base – the collective data from its users is already proving a very powerful resource.
- Genetic Programming
This session centred around some basic aspects of Genetic Algorithms/Evolutionary Computing and Emergent properties of evolutionary systems. Delegates focused on creating virtual ants (with Python) to solve mazes and by visualising their creatures with Processing (above), Richard Jones enabled developers to work on something a bit different!
- Web Security
Ben Charlton from the University of Kent delivered an excellent walk-through of the most significant and very common threats to web applications. Working from the OWASP Top 10 project, he discussed each threat with real world examples. Great stuff – important for all developers to see.
- Replicating 3D Printer: RepRap
Adrian Bowyer demonstrated RepRap – short for Replicating Rapid-prototyper. It’s an open source (GPL) device, able to create robust 3D plastic components (including around half of its own components). Its novel capability of being able to self-copy, with material costs of only €350 makes it accessible to small communities in the developing world as well as individuals in the developed world. His inspiring talk was well received and this super illustration of open information’s far reaching implications captured everyone’s imagination.
All in all, a great conference. A broad spread of topics, with the right mix of sit-and-listen to get-involved activities. Whilst Dev8D is a fairly chaotic event, it’s clear that it generates a wealth of great ideas, contacts and even new products and services for academia. See Dev8D’s Happy Stories page for a record of some of the outcomes. I’m now looking forward to seeing how some of the prototypes evolve and I’m definitely looking forward to Dev8D 2011.
