REPUK
Aggregation of scholarly resources
Linked Data
HTTP URIs, REST, ROA
Implications for SOA
“ If your mindset is SOA, and putting up an API, then what falls out of this mentality is a need to document the API. This is inherently un-RESTful” From interview with Andy Powell, 16 th Nov 2009
Opendata Manchester

Can we convince IT Managers, VC etc. it’s worth it?
Realistic expectations
“ ..the people sort of in charge of the kind of data thing knew so little about their data structures”
“ I’ve had a whole bunch of meetings to get one dataset, been fobbed off, and literally just never get anywhere” Tom Steinberg, Director of MySociety (from Nodalities issue 8)
prove a simple tangible benefit

How raw is raw?
txt raw, csv raw, rdf raw?
Commitment, sustainability
What’s the payoff for O’Reilly, BBC etc of using Linked Data?
Why didn’t it work the first time?
What’s different now?
Need to work out what Linked Data does that other things don’t

What about the Semantic Web?
Inferencing etc.

Some other issues
To RDF or not to RDF
Usability
Sustainability
Provenance
Licensing
Reliability

Sustainability
Ed Summers at the Library of Congress created http://lcsh.info
Linked Data interface for LOC subject headings
People started using it

Library of Congress Subject Headings

Data Licensing
RDF Book Mashup
makes information about books, their authors, reviews, and online bookstores available on the Semantic Web
Uses Amazon Web Services but contravenes terms and conditions

Provenance
OK if data ‘watermarked’
But can often be a problem
VOID can help (apparently!)
