Open (linked) Bibliographic Data A perspective from Cambridge University Library Ed Chamberlain – Systems Development Librarian

Why did you decide to expose your bibliographic data?
Natural follow on for ‘meeting reader in their (online) place’
Already exposing data to others (OCLC, COPAC, SUNCAT etc.)
Value for money for taxpayer
Internal academic pressure

Learn good things from other people …

COMET (Cambridge Open METadata) What does it entail?
Releasing large amount of records under an Open Data Commons License
Formats include Marc21 and linked RDF with a triple-store
Road-test linking to OCLC resources (FAST / VIAFF)
Supporting documentation on whole process

The library sector’s ambition around resource discovery ( … what I think they should be) #1
Success of ‘out-of-domain exposure’ outside of cultural heritage

Multiple points of discovery at multiple levels for multiple audiences - built on a shared community platform of data

Services for undergraduates
Services for academics
} Services for developers

COMET (Cambridge Open METadata) : What barriers are you facing and how are you overcoming them?
Licensing (OCLC)
RDF vocab and mappings
Triplestores

Licensing
The preferred ideal …
Full unrestricted access
Creative Commons Zero / Public Domain Data License …
Complete dump of data
There are other types of open …
Examining all license options
But any published data is better than none at all …
No good legal reason not to publish
Will need some sort of license - more open the better

Gah!

Triplestores
Not fun
Keep it sweet and simple for now

What benefits have you gained / do you expect to gain?
Understanding of capabilities and concepts of linked data
Limitations of marc21 encoded data
Lean about FAST and VIAF (next-gen authority control!)
More down the line …

Strong platform for future development, may take several ‘cycles’
Growth area in government and HE for linked data – makes sense to be in the same sphere
Hugh scope for back office benefits
In what ways does the new landscape of linked open data potentially change what is possible for the libraries sector ?

How do you wish to go forward? What are your plans post-COMET?
Encourage others – provide useful documentation and code
Advice on licensing
Expose more data – from different sources
Do something cool with it!

Beyond bibliography … Bibliographic Holdings FAST subject headings Libraries VIAFF name authority Transactions Special collections Archives Creator / entity Place of publication LCSH subject headings Course lists Language Librarians
