  10. 10. The Linked Data Concept • A method of publishing structured data on the Web, allowing it to be connected and enriched, and facilitating linking between related resources. • Linked Data standards such as RDF (Resource Description Frameowork) allows semantic definitions to be applied to information, using statements called ‘triples’ in the form subject, predicate, object. DRI Presentation
  11. 11. A key principle of Linked Data is that HTTP URIs are used to name the semantic elements of the dataset DRI Presentation

  15. 15. The Longfield Maps & Linked Logainm URIs 1,570 maps catalogued in MarcXML - <marc:datafield tag="650" ind1="" ind2=""> <marc:subfield code="a">Land tenure</marc:subfield> <marc:subfield code="z">Ireland</marc:subfield> <marc:subfield code="z">Rathdown (Barony)</marc:subfield> </marc:datafield> - <marc:datafield tag="650" ind1="" ind2=""> <marc:subfield code="a">Land use surveys</marc:subfield> </marc:datafield> DRI Presentation
  16. 16. URIs & the NLI Catalogue • • • Application of authoritative place name data to catalogue records Single URI for the place name: Allows users to search in either Irish or English Redirects searches for variant place names – “Ceara” or “Cera” will redirect to “Carra” Redirects within hierarchy – search for townland not found in the catalogue could redirect to maps for the related barony Potential to draw in contextual information from other datasets, eg. current population, meteorological data etc DRI Presentation
