RDF-based ADMS Model

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
