Can we connect both contexts using linked data?

Two sides

Publishing linked data

URIs for all things

Preferably persistent

Return data in ‘machine readable format’

Triples/RDF/etc.

Vocabulary/ontology


University library

Using linked data

1. Construct URIs based on native metadata

2. Process returned RDF/Triples/etc.

3. Present results

Aleph key ≠ key No internal links to common entity

No central “Work” String matching
