2. Digital Enterprise Research Institute www.deri.ie Rationale We propose an RDF model which has all the core properties needed to model an asset We also recommend reusing a set of properties

3. Digital Enterprise Research Institute www.deri.ie LOD vocabularies List of the LOD vocabularies that will be reused in ADMS :  Data Catalog Vocabulary (dcat): http://www.w3.org/ns/dcat http://www.w3.org/ns/dcat  Dublin Core (dc): http://purl.org/dc/terms/http://purl.org/dc/terms/  Friend Of Friend (foaf): http://xmlns.com/foaf/0.1/  Description of a Project (doap): http://usefulinc.com/ns/doap#

6. Digital Enterprise Research Institute www.deri.ie Value Vocabulary Classes like adms:Domain,adms:Country adms:Model, adms:SyntaxSpec and adms:SemanticSpec are value vocabulary as described in the ADMS draft These values will be described as skos:Concept Values (codelists) should be provided to complete the model

7. Digital Enterprise Research Institute www.deri.ie Versioning (1/2) Each asset should be connected to its latest release version The model is updated each time new release is added Each release is related to the previous version

8. Digital Enterprise Research Institute www.deri.ie Versioning (2/2)

15. Digital Enterprise Research Institute www.deri.ie Example rdf:type adms:Asset ; dc:title "Access to Biological Collection Data" ; adms:release ; dct:hasVersion ; adms:asset adms:release dc:hasVersion

16. Digital Enterprise Research Institute www.deri.ie Access Control Each user is a member of a user group Access policy describes how assets are available for users and the permissions involved. Each request by a user to access the assets goes through a policy enforcement mechanism that assures proper access control. Solutions for policy description and enforcement do exist in the Semantic Web world
