JISC's “Discovery” Programme
We want to find things
Geographic search of archives is important!
Outcomes of GOLD
• CSW harvesting
• automated Linked Data publication
• well known and frequently used vocabularies e.g. FOAF, Dcat.
• Need for core, common vocabularies
• competing approaches to representing geometry
Is Linked Data the panacea to resource discovery and reuse its proponents claim?
5 Stars of Linked Open Data
★ Available on the web (whatever format) but with an open licence, to be Open Data
★★ Available as machine-readable structured data (e.g. excel instead of image scan of a table)
★★★ as (2) plus non-proprietary format (e.g. CSV instead of excel)
★★★★ All the above plus, Use open standards from W3C
(RDF and SPARQL) to identify things, so that people can point at your stuff
★★★★★ All the above, plus: Link your data to other people’s data to provide context
