By a mile the highlight of last week or so was the 2nd Linked Data meet-up. Silver and Georgi did a great job of organising the day and I came away with a real sense that not only are we on the cusp of seeing a lot of data on the web but also that the UK is at the centre of this particular revolution. All very exciting.
In terms of Wildlife Finder there are a few things that I wanted to highlight:
If you’re interested in the RDF and how we’re modelling the data we’ve documented the wildlife ontology here. In addition to the ontology itself we’ve also included some background on why we modelled the information in the way we have.
If you want to get you’re hands on the RDF/XML then either add .rdf to the end of most of our URLs (more on this later) or configure your client to request RDF/XML – we’ve implemented content negotiation so you’ll just get the data.
But… we’ve not implemented everything just yet. Specifically the adaptations aren’t published as RDF – this is because we’re making a few changes to the structure of this information and I didn’t want to publish the data and then change it. Nor have we published information on the species conservation status that’s simply because we’ve not finish yet (sorry).
It’s not all RDF – we are also marking-up our taxa pages with the species microformat which gives more structure to the common and scientific names.
I’ve really been neglecting this blog recently – apologies but my attention has been elsewhere recently. Anyway, while I get round to actually writing something here’s a presentation I gave at the Online Information Conference recently.
The presentation is largely based upon the article Michael and I wrote for Nodalities this time last year.
It’s starting to feel like the world has suddenly woken up to the whole Linked Data thing — and that’s clearly a very, very good thing. Not only are Google (and Yahoo!) now using RDFa but a whole bunch of other things are going on, all rather exciting, below is a round up of some of the best. But if you don’t know what I’m talking about you might like to start off with TimBL’s talk at TED.
The BBC has announced a couple SPARQL endpoints, hosted by talis and openlink
Both platforms allow you to search and query the BBC data in a number of different ways, including SPARQL — the standard query language for semantic web data. If you’re not familiar with SPARQL, the Talis folk have published a tutorial that uses some NASA data.
A social semantic BBC?
Nice presentation from Simon and Ben on how social discovery of content could work… “show me the radio programmes my friends have listen to, show me the stuff my friends like that I’ve not seen” all built on people’s existing social graph. People meet content via activity.
PriceWaterhouseCooper’s spring technology forecast focuses on Linked Data [pwc.com]
“Linked Data is all about supply and demand. On the demand side, you gain access to the comprehensive data you need to make decisions. On the supply side, you share more of your internal data with partners, suppliers, and—yes—even the public in ways they can take the best advantage of. The Linked Data approach is about confronting your data silos and turning your information management efforts in a different direction for the sake of scalability. It is a component of the information mediation layer enterprises must create to bridge the gap between strategy and operations… The term “Semantic Web” says more about how the technology works than what it is. The goal is a data Web, a Web where not only documents but also individual data elements are linked.”
