14 Guideline: Licensing models & mechanisms Add "rights" metadata in the dataset description 1 DCAT (e.g., VoID, DCAT) Data catalog vocabulary 07/05/

15 Guideline: Licensing models & mechanisms 1 Add "rights" metadata in the dataset description (e.g., VoID, DCAT) DCAT Data catalog vocabulary 2 Use standard predicates to declare "rights" statements (e.g., Dublin Core terms: dc:rights, dct:license) 07/05/

16 Guideline: Licensing models & mechanisms 1 Add "rights" metadata in the dataset description (e.g., VoID, DCAT) DCAT Data catalog vocabulary 2 Use standard predicates to declare "rights" statements (e.g., Dublin Core terms: dct:rights, dct:license)? Standard license available 3a 07/05/

17 Guideline: Licensing models & mechanisms 1 Add "rights" metadata in the dataset description (e.g., VoID, DCAT) DCAT Data catalog vocabulary 2 Use standard predicates to declare "rights" statements (e.g., Dublin Core terms: dc:rights, dct:license)? Standard license available 3a Use URI of standard license e.g., CC0 Yes 07/05/

19 Demo: Conditional access to Linked Data Prototype developed at the Ontology Engineering Group. A licenses-aware Linked Data server and a data policies and licenses manager Using Web standards (DCAT descriptions, SPARQL constructs, ODRL RDF policies, etc.) 07/05/

20 META-SHARE license expressed as RDF with ODRL Resources can be provided with provenance and flexible licenses. For example, specifying availability only for research institutions of a rdf: rdfs: dcat: dct: odrl: prov: < < a dcat:dataset ; dct:license [ a odrl:policy; rdfs:comment Gives access to the resource to Spanish research institutions. Redistributing or transforming the work is forbidden ; odrl:permission [ a odrl:permission; odrl:action odrl:reproduce; odrl:constraint [ a odrl:constraint; odrl:industry Research ], [ a odrl:constraint; odrl:location ES } ] ; odrl:prohibition [ a odrl:prohibition; odrl:action odrl:derive, odrl:distribute ] ; ]; prov:wasgeneratedby [ prov:endedattime "Thu Apr 03 00:07:07 CEST2014"^^xsd:date ; prov:wasassociatedwith 07/05/2014 ]. 20
