Published on

What is the semantic web and what does it hold for the book industry? Graham Bell, Chief Data Architect at EDItEUR (http://www.editeur.org/), will give us a tour of the semantic web and show us the way linked data has begun to be used by libraries and the other potential it holds for the book industry.

  12. 12. Linked data• expresses metadata as a collection of triples• uses URIs to represent relations and entities• prefers persistent HTTP URIs so they can be ‘looked up’ to get further details • the data can be ‘self-describing’• is intended to be flexible and extensible, because it’s ‘schemaless’• isn’t new• is not intended for human consumption

  18. 18. An aside• linked data is often confused with the concept of ‘LinkedOpenData’ • linked data, but with an ideological view that data should be open and freely available for anyone to reuse without restrictions • much of the data that’s claimed to be LOD is infact data where the owner has omitted to post a licence governing its reuse • most of the truly open data is often data produced by the public sector
  19. 19. An aside• linked data is often confused with the concept of ‘LinkedOpenData’ • linked data, but with an ideological view that data should be open and freely available for anyone to reuse without restrictions • much of the data that’s claimed to be LOD is infact data where the owner has omitted to post a licence governing its reuse • most of the truly open data is often data produced by the public sectorhttp://lod-cloud.net/
  20. 20. Linking data• linking depends on shared entities • we need to be sure we are really talking about the same thing – not just two people with the same name, but actually the same contributor • unambiguous identifiers • controlled vocabularies, taxonomies and clear, shared semantics based on shared data models• linked data needs careful data modelling, and a concern for semantics and identity – and it’s technically challenging. There’s a steep learning curve
  21. 21. Linked data challenges• linked data contains no provenance• metadata licensing is often unclear• needs shared persistent identifiers –but much of the current linked data activity is experimental and lacks sustainability• poor legacy data – we’re still struggling with the schema-led approach…• and where’s my record gone?
  22. 22. Linked data promise• just another way of expressing the same data • book metadata is already ‘data with links’ • linked data removes the limits of ‘the record’• but optimised for machines, not people • Tim Berners-Lee’s ‘semantic web’ • allows machines to ‘browse’ for other data – so if your book is set in Sweden, then it can automatically be linked to other sources of data about Sweden or to other Swedish things• could change the game of ‘discoverability’
