Figure 11 — Conversion of association classes
The encoding rule is to perform the mapping and then encode the model in the standard manner.

Target type GML application schema
Name Association class conversion rule
Dependency http:www.opengis.netspecGML3.3requml2gml
Requirement http:www.opengis.netspecGML3.3reqassocClasstransform
Before applying the GML encoding rule, any UML association class shall be transformed as follows in the following description the source class of the association is called S and
the target class is called T:
- The association class A is transformed into a regular class with the same name, stereotype, tagged values, constraints, attributes, relationships.
- The association is replaced by two associations, one from S to A SA and one from A to T AT.
- The characteristics of the association end in particular role name, navigability, multiplicity, documentation of the original association class at T are used for
association ends at A of SA and at T of AT with the exception that the multiplicity at the association end at T of association AT is set to 1.
- The characteristics of the association end of the original association class at S are used for association ends at S of SA and at A of AT with the exception that the
multiplicity at the association end at S of association SA is set to 1.
Requirement http:www.opengis.netspecGML3.3reqassocClassstereotype
The UML association class shall have either no stereotype or a stereotype FeatureType.
