2. "The Ontology Engineering Group, within the context of its Linked Data projects, is pleased to announce that the datos.bne.es [1] initiative has been launched. datos.bne.es is an open initiative aimed at enriching the Web of Data with library data from the Spanish National Library. The SPARQL endpoint is available at [2].The RDF generation from MARC 21 records was done using our tool MARiMbA [3], which allows non-technical users to work on the mappings from MARC21 metadata to RDF using different RDFS/OWL vocabularies.This initiative is part of the project “Linked data at the BNE”, supported by the BNE in cooperation with the Ontology Engineering Group (OEG) at the Universidad Politécnica de Madrid (UPM).  With this initiative, the BNE takes the challenge of publishing bibliographic and authority data in RDF, following the Linked Data Principles and under the CC0 (Creative Commons Public Domain Dedication) open license. Thereby, Spain joins the initiatives that libraries from countries such as the United Kingdom and Germany have recently launched.Approximately 2.4 million bibliographic records have been transformed into RDF. They are modern and ancient monographies, sound-recordings and musical scores. Besides, 4 million authority records of persons, corporate names, uniform titles and subjects have been transformed. The transformation process has generated around 58 million RDF triples and about 600K owl:sameAs links to other datasets such as DBPedia or VIAF. More information can be found in the DataHub entry [3]"   Daniel Vila, 13-2-2012 http://lists.w3.org/Archives/Public/semantic-web/2012Feb/0082.html

10. Linked data – en definisjon "A term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF." Fra: http://linkeddata.org/ URI = Uniform Resource Identifier 2006 RDF = Resource Description Framework

11. Linked Data - hvordan • Use URIs as names for things • Use HTTP URIs so that people can look up those names. • When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL) • Include links to other URIs. so that they can discover more things. Fra: http://www.w3.org/DesignIssues/LinkedData.html HTTP URIs = URLs

12. Andre sentrale byggesteiner i tillegg til URIer og RDF • XML • Vokabular
