The document discusses linked data and its implications for publishers, emphasizing the importance of metadata standards in the publishing industry and how linked data can enhance data discoverability. It outlines the role of Editeur, a not-for-profit organization focused on developing metadata standards for books and e-books, advocating for persistent identifiers and shared semantics. The challenges and promises of linked data are highlighted, including the need for careful data modeling and the potential for machine-driven access to related content.

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. 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

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. 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. 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’
