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*
1. Use URIs to name things; not only documents, but also people, locations, concepts, etc.
2. To enable agents (human users and machine agents alike) to look up those names, use HTTP URIs
3. When someone looks up a URI we provide useful information; with 'useful' in the strict sense we usually mean structured data in RDF.
4. Include links to other URIs allowing agents (machines and humans) to discover more things

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 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?
Digital Enterprise Research Institute www.deri.ie
Linking Open Data
24 of XYZ
over 100 open data sets, incl. Wikipedia, Geonames, etc., providing over 4.7 billion RDF triples, interlinked by approximately 142 million RDF links
Digital Enterprise Research Institute www.deri.ie
So, how does it work?
The LiDRC operates within so calledResearch Themes
Digital Enterprise Research Institute www.deri.ie
LiDRC’s Research Themes
Publishing
Discovery Application Domains
Streamed Linked Data
Digital Enterprise Research Institute www.deri.ie
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.
