SCIENTIFIC AUDIOVISUAL MATERIALS AND LINKED OPEN DATA: THE TIB PERSPECTIVE

What is Linked Open Data?
2
Linked Data Principles
•Use URIs as names for things
•Use HTTP URIs so that people can look up those names
•When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL)
•Include links to other URIs. so that they can discover more things
Linked Data Principles + a public domain license = Linked Open Data (LOD)

How to cope with complexity? Ontologies

Standards
4Figure: https://xkcd.com/927/
There is no standardised way to publish Linked Open Data (Zuiderwijk et al., 2012).
Common best practices:•a local RDF store,•an ontology/vocabularies that relates data items (internally and externally),•data reuse.

Summary
• Research libraries manage textual and non-textual digital information
• The management generates library data
• Linking library data using standards increases the interoperability of the data
• Linked Open Data promotes multilingual facilities, data reuse and semantic applications
• TIB|AV-Portal is weaving step by step into a linked data environment
