People are interested in information, subject areasNot necessarily in traditional library items (publications, documents)
RDA Seminar, Rotterdam, November 2, 2011 38
University library
FRBR – so far so good?
Improvement: relations between editions, authors, subjects.
But: still focused on traditional library material Publications (physical and digital) Only library’s own holdings Journals/articles? Hierarchical, no horizontal relations Document centric, not information centric

Linked (Open) Data – Why?
Make introverted systems extroverted
Combine information from different sources
Add value for users
RDA Seminar, Rotterdam, November 2, 2011 40
University library
Linked (Open) Data – How?
Make implicit links explicit Add links to/from other sources Use URIs Use RDF/Triples Use Open License
RDA Seminar, Rotterdam, November 2, 2011 41

URIs
Unique identifiers on the web
