Facts & FiguresThe Linked Data Research Centre (LiDRC) is an effort to bundle activities around linked dataOperating horizontal to units, appointed to drive and lead the linked data research and developmentLaunched in June 2009Currently we are11 DERI researcher, and work together with 9 international peers

Linked Data Principles* Use URIs to name things; not only documents, but also people, locations, concepts, etc. To enable agents (human users and machine agents alike) to look up those names, use HTTP URIs When someone looks up a URI we provide useful information; with 'useful' in the strict sense we usually mean structured data in RDF. Include links to other URIs allowing agents (machines and humans) to discover more things(*) http://www.w3.org/DesignIssues/LinkedData.html

Principles applied …Linked data principles, aka ‘RDF over HTTP’ are good, but they need to be appliedLinked data principles applied to… open, freely available datasets (in various source formats such as CSV, XML, etc.), such as WikipediaLinking Open Data (LOD)… enterprise data (CRM, XBRL, etc.)Enterprise linked data (eLD)… (news) feeds, sensors, etc.Streamed linked data… and what is about your domain?

Linking Open Dataover 100 open data sets, incl. Wikipedia, Geonames, etc., providing over 4.7 billion RDF triples, interlinked by approximately 142 million RDF links24 of XYZ

So, how does it work?The LiDRC operates within so calledResearch Themes

LiDRC’s Research ThemesDiscoveryApplication Domains Publishing Streamed Linked Data

LiDRC’s Research ThemesPublishing – creation, interlinking and deployment of linked dataDiscovery – finding and using linked dataApplication Domains – from specific content domains (software engineering, multimedia, etc.) to linked data driven applications)Streamed Linked Data – researches data stream such as news feeds, microblogging, RFID/sensor data, etc.
