|---|---|---|---|---|---|---|---|
Packages
|
|||||||
ApplicationSchema |
The GML workspace package, which holds all the GML modeling elements. You can export the contents of this package to produce the GML Application Schema.
|
||||||
Leaf |
A stereotyped package that can be created under an Application Schema. Leaf is a convenient package for grouping elements within an Application Schema. If the value of the tag xsdDocument on this package is empty, the contents of this package will be exported as a part of the parent package whose tag xsdDocument is not empty.

||||||
Elements
|
|||||||
FeatureType |
An extended UML Class that maps to an XSD Global element, whose content model is a globally scoped XML Schema type derived by direct/indirect extension of gml:AbstractFeatureType.
|
||||||
Type |
An extended UML Class that maps to an XSD element, whose content model is a globally scoped XML Schema type derived by direct/indirect extension of gml:AbstractGMLType.
|
||||||
DataType |
An extended UML Class that maps to an XSD Global element, whose content model is a globally scoped XML Schema complexType.
|
||||||
CodeList |
An extended UML Class, that maps to:
|
||||||
Union |
An extended UML Class that maps to an XSD Choice group, whose members are GML objects or features, or objects corresponding to DataTypes.
|
||||||
Enumeration |
An extended UML Class that is a restriction of XSD string with enumeration values.
|
||||||
Relationships
|
|||||||
Generalization |
Identifies an element as a specialized descendant of another element, containing additional properties. This relationship is allowed between:
An element can have a maximum of one Generalization connector.
|
||||||
Association |
Identifies the connection between two elements. Only navigable Association Ends will be mapped to GML Application Schema.
|
||||||
Aggregation |
An extended UML Association that shows that an element is composed of other elements.
|
||||||
Composition |
An extended UML Association that is a stronger form of Aggregation, indicating ownership of the whole over its parts.
|
||||||
Attribute
|
|||||||
Property |
An extended UML Attribute, whose type is either a property type (if the type is a complex type) or a simple type.
|
||||||
Association Role
|
|||||||
Property |
An extended UML Association Role, whose type is always a property type.
