  • The BBC is a big place and I would like to suggest that in someways it represents a microcosm of the wider web. We produce so much content that traditional &apos;left hand nav&apos; style navigation doesn&apos;t work. From a UX POV, nor from a coordination and governance POV. <br /> <br /> <br /> <br /> As a result the BBC has historically created a series of microsite. Each coherent in their own right but not across the breadth of BBC content. <br /> <br /> <br /> <br /> Consider for example I can navigate around a Radio 4 site about the opening of the LHC... but...
  • I can&#x2019;t find everything to BBC knows about Brian Cox... but equally I can&#x2019;t find everything
  • Paul Weller, or any other artist, nor can I find everything
  • But things are changing.. <br /> <br /> <br /> <br /> It has been my honour to work on a few of projects where we took a different approach. Starting with the data and how people think about it rather than starting with the web page down. <br /> <br /> <br /> <br /> And when I say data I really mean starting with understanding what things people care about and giving each of those things a URI. <br /> <br /> <br /> <br /> /programmes - ensures every programme the BBC broadcasts has a web presence, has a URI. And that that URI can be dereferenced to return an HTML document, an RDF document, JSON, iCal or mobile views. <br /> <br /> <br /> <br /> /music - is built with MusicBrainz and gives us a page for every artist the BBC plays. Because it&#x2019;s built with Musicbrainz not only do we get a URI per artist we also get links into the rest of the web and lovely webscale identifiers. <br /> <br /> <br /> <br /> I&#x2019;m now working on a new project, BBC Earth, which is seeking to bring the BBC&#x2019;s Natural History content online in a similar fashion. <br /> <br /> <br /> <br /> A page per species, habitat, behaviour and adaptation - all linked to the programme space and the wider web through dbpedia and elsewhere. <br /> <br /> <br /> <br /> And of course as with programmes and music the API is the website - the URIs can return RDF, JSON etc. as well as HTML.
  • Of course what I&#x2019;m talking about is Linked Data... even if we didn&#x2019;t quite realise that when we started. <br /> <br /> <br /> <br /> But the idea that we should care about our URIs, care about having one per concept, care about having machine representations for those resources instead of a separate API has helped us build a coherent, scalable, sane service. One that we hope is a bit more human literate. <br /> <br /> <br /> <br /> Linking Open Data is a grassroots project to use web technologies to expose data on the web. It is for many people synonymous with the semantic web - and while this isn&#x2019;t quite true. It does, as far as I&#x2019;m concerned, represent a very large subset of the semantic web project. <br /> <br /> <br /> <br /> Although, curiously, it can also be thought of as the &#x2018;the web done right&#x2019; - as it was originally designed to be. <br /> <br /> <br /> <br /> But what is it? <br /> <br /> <br /> <br /> Well it can be described with 4 simple rules.
  • The web was designed to be a web of things, not just a web of documents. <br /> <br /> <br /> <br /> Those documents make assertions about things in the real world but that doesn&#x2019;t mean the identifiers can only be used to identify web documents. <br /> <br /> <br /> <br /> Just as a passport or driving license, in the real world, can be thought of as identifiers for people so URI can be used as identifiers for people, concepts or things on the web. <br /> <br /> <br /> <br /> Minting URIs for things rather than pages helps make the web more human literate because it means we are identifying those things that people care about.
  • The beauty of the web is its ubiquitous nature - the fact it is decentralised and able to function on any platform. This is because of TimBL&#x2019;s key invention the HTTP URI. <br /> <br /> <br /> <br /> URI&#x2019;s are globally unique, open to all and decentralised. <br /> <br /> <br /> <br /> Don&#x2019;t go using DOI or any other identifier - on the web all you need is an HTTP URI.
  • And obviously you need to provide some information at that URI. When people dereference it you need to give them some data - ideally as RDF as well as HTML. <br /> <br /> <br /> <br /> Providing the data as RDF means that machines can process that information for people to use. Making it more useful.
  • And of course you also need to provide links to other resources so people can continue their journey. <br /> <br /> <br /> <br /> And that means contextual links to other resources elsewhere on the web, not just your site. <br /> <br /> <br /> <br /> And that&#x2019;s it. Pretty simple. <br /> <br /> <br /> <br /> And I would argue that, other than the RDF bit, these principles should be followed for any website - they just make sense.
  • Before the Web people still networked their computers - but to access that network you needed to know about the network, the routing and the computers themselves. <br /> <br /> <br /> <br /> For those in their late 30s you&#x2019;ll probably remember the film War Games - because this was filmed before the Web they had to find and connect to each computer. The joy of the web is that it adds a level of abstraction - freeing you from the networking, routing and server location and letting you focus on the document.
  • The evolution from ARPANET, to Internet, to Web gave us increasing levels of abstraction, making the technology more and more human centric because it allowed us to stop worrying about the location of servers and their networking and start thinking about documents. <br /> <br /> <br /> <br /> The semantic web project I hope will help the BBC to move away from caring about the document and towards the ideas, concepts and things we care about. <br /> <br /> <br /> <br /> So you can find all things Brian Cox or follow your nose to from an episode of Blue Planet via a page about dolphins to everything the BBC knows about ecolocation. <br /> <br /> <br /> <br /> Following the principles of Linked Data allows us to add a further level of abstraction - freeing us from the document and letting us focus on the things, people and stuff that matters to people. <br /> <br /> <br /> <br /> It helps us design a system that is more human literate, and more useful. <br /> <br /> <br /> <br /> This is possible because we are identifying real world stuff and the relationships between them.
  • Making data available as data means it&#x2019;s more useful because other people can build with it to create interesting things for people. <br /> <br /> <br /> <br /> Of course you don&#x2019;t have to use Linked Data to achieve this - there are other ways of doing it - lots of sites now provide APIs which is good just not great. <br /> <br /> <br /> <br /> Each of those APIs tend to be proprietary and specific to the site. As a result there&#x2019;s an overhead every time someone wants to add that data source. <br /> <br /> <br /> <br /> These APIs give you access to the silo - but the silo still remains. <br /> <br /> <br /> <br /> Using RDF and LOD means there is a generic method to access data on the web.
  • So what are we doing at the BBC? <br /> <br /> <br /> <br /> First up it&#x2019;s worth pointing out the obvious, the BBC is a big place and so it would be wrong to assume that everything we&#x2019;re doing online is following these principles. But there&#x2019;s quite a lot of stuff going on. <br /> <br /> <br /> <br /> There are two areas of activity - the first a root and branch development - tackling a specific domain and a second retrofitting technologies to the existing, legacy content to make it more coherent.
  • There&#x2019;s a lot of it. Loads. And we can&#x2019;t very well ignore it or leave it behind. We need a way to describe and link the existing microsites together.
  • We are doing that by using the wikipedia text as an evidence set to recommend IDs <br /> <br /> <br /> <br /> We can start to automate some of this to extract concepts and recommend tags before publishing a navigation badge back on the page.
  • These Navigation badges then link off to topic or aggregation pages which in turn link through to other content pages. Allow people to navigate between pieces of content, via topic pages, following their areas of interest.
  • What about the new stuff? <br /> <br /> <br /> <br /> Well the BBC&#x2019;s programme support, music discovery and, soon, natural history content are all being designed and build from the ground up following the LOD principles described earlier. <br /> <br /> <br /> <br /> In other words persistent HTTP URIs that can be dereferenced to HTML, RDF, JSON and mobile views for programmes, artists, species and habitats each with further links on to other resources.
  • That means we have a page for every programme the BBC broadcasts on TV and Radio.
  • And we have separate pages for every artist the BBC plays on the new music site.

  • The new stuff... Internet http://www.flickr.com/photos/transkamp/54371294/
  • A page per programme
  • In the music domain we have a page for every artist the BBC plays
  • And for natural history... species pages...
  • ...habitat pages...
  • ...and adaptation pages
  • But the context lives in the joins between these domains
  • Programmes on species pages
  • Track listings on episode pages linked to artist pages
  • Programmes on artist pages
  • And because the web is about URIs not pages
  • Seperate URLs for each resource bbc.co.uk/music/artists/:artist/reviews
  • bbc.co.uk/music/artists/:artist/news
  • and the rest of web bbc.co.uk/music/artists/:artist/links
  • In other words everything is addressable and therefore meshable across the web and across domains with the BBC Droplet highway http://www.flickr.com/photos/cesarcabrera/446101505/
