Representation of association classes #21

Closed jechterhoff closed 7 years ago

jechterhoff commented 8 years ago

Description

Association classes are not supported by the schema conversion rules in ISO/DIS 19150-2, but are required for INSPIRE application schemas.

The GML 3.3 standard defines a pattern to transform an association class into equivalent UML model elements (consisting of UML classes and associations only). A similar pattern is suggested in a note of the Semantic Web Best Practices and Deployment Working Group.

We propose that, in general, the approach taken in GML 3.3 should also be used for deriving INSPIRE RDF schemas.

However, each of the rare cases where association classes are used in the INSPIRE conceptual schemas should be reviewed to determine if an optimized mapping to RDF exists.

The proposal has been implemented in the guidelines, see the section Association class.
