What is it about? a new cluster? a new project? a new stream? a new unit?
What is it about? No
What is it about? actually, it is about …
What is it about? YOU!

Facts & Figures The Linked Data Research Centre (LiDRC) is an effort to bundle activities around linked data Operating horizontal to units, appointed to drive and lead the linked data research and development Launched in June 2009 Currently we are 11 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

Link to other entities typed links == relations between entities and there are many relations one can think of …

Principles applied … Linked data principles, aka ‘RDF over HTTP’ are good, but they need to be applied Linked data principles applied to … open, freely available datasets (in various source formats such as CSV, XML, etc.), such as WikipediaLinking 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 Data over 100 open data sets, incl. Wikipedia, Geonames, etc., providing over 4.7 billion RDF triples, interlinked by approximately 142 million RDF links 24 of XYZ
So, how does it work? The LiDRC operates within so calledResearch Themes
LiDRC’s Research Themes Discovery Application Domains Publishing Streamed Linked Data
LiDRC’s Research Themes Publishing – creation, interlinking and deployment of linked data Discovery – finding and using linked data Application 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.
