Data conversion
   Choosing datasets
   Choosing description
   Extraction
   Linking
   Distribution
Choosing description
   Domain ontologies
       Established, popular (Dublin Core, SKOS)

Linking




Library data already contain links
Links to resources identified
by code values
Links to classification notations
Links to persons
Links to geographical entities
and institutions
„Outsourcing“ authorities
   DBPedia
   VIAF
   Geonames

   Single interface to the datasets
