Linked Data Principals
Linking Open Drug Data

3. The Classic Web Single information space Built on URIs
Web Browsers
Search Engines
Single information space
Built on URIs
globally unique IDs
retrieval mechanism
Built on Hyperlinks
are the glue that holds everything together

5. Data Objects Identified with HTTP URIs
rdf:type
pd:cygri
foaf:Person
foaf:name
Richard Cyganiak
foaf:based_near
dbpedia:Berlin
pd:cygri = dbpedia:Berlin =
Forms an RDF link between two data sources

8. The Linked Data Cloud
> 2 billion RDF triples
> 3 million links

9. Linking Open Drug Data HCLSIG task started October 1, 2008
Primary Objectives
Survey publicly available data sets about drugs
Publish and interlink these data sets on the Web
Explore interesting questions that could be answered if the data sets are linked

15. Conclusions Rapidly growing cloud of Linked Data
Many data sets related to life sciences
W3C’s HCLSIG has published 4 drug related data sets
Improvements needed to linking algorithms and data browsers
