  15. 15. SOME ISSUES • Pure FRBR representation not always possible dct:subject, dct:language at Manifestation level instead of Work level • Around 30% of bibliographic records still not connected to their Expression • Manifestations are mostly described with strings, not many links • Does the modelling seem to complex to people outside the library community?
  16. 16. NEXT STEP Data portalAPIs MARC 21, XML, metadata schemas BNE Knowledge Graph (RDF with rich data model) For humans and machines (schema.org) For developers JSON(LD) LDP, LD API SPARQL HTTP RICH POOR?
