The Linked Data Research Centre (LiDRC) is a new effort within DERI to advance linked data research and development. The LiDRC operates across existing units and has 11 DERI researchers working with 9 international peers. Its research themes include publishing, discovery, application domains, and streamed linked data. The LiDRC contributes linked data infrastructure, provides tools and libraries, and participates in standards activities. It is calling for input on a technical report about linked data applications.

9. 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

23. 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?

24. 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

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

26. LiDRC’s Research ThemesDiscoveryApplication Domains Publishing Streamed Linked Data

27. 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.
