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

LOD vocabularies
List of the LOD vocabularies that will be reused in ADMS : Data Catalog Vocabulary (dcat):

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

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

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
