Complex type abstract

AbstractGeometryType

gml:AbstractGeometryType

Defined in gml/geometryBasic0d1d-extract-v3_2_1.xsd:18

All geometry elements are derived directly or indirectly from this abstract supertype. A geometry element may have an identifying attribute (gml:id), one or more names (elements identifier and name) and a description (elements description and descriptionReference) . It may be associated with a spatial reference system (attribute group gml:SRSReferenceGroup). The following rules shall be adhered to: - Every geometry type shall derive from this abstract type. - Every geometry element (i.e. an element of a geometry type) shall be directly or indirectly in the substitution group of AbstractGeometry.

    The value of this property is a remote text description of the object. The xlink:href attribute of the gml:descriptionReference property references the external description.
  - gml:identifiergmlBase-extract-v3_2_1.xsd:117 0..1 gml:CodeWithAuthorityType
    
    Often, a special identifier is assigned to an object by the maintaining authority with the intention that it is used in references to the object For such cases, the codeSpace shall be provided. That identifier is usually unique either globally or within an application domain. gml:identifier is a pre-defined property for such identifiers.
  - gml:namegmlBase-extract-v3_2_1.xsd:112 0..unbounded gml:CodeType
    
    The gml:name property provides a label or identifier for the object, commonly a descriptive name. An object may have several names, typically assigned by different authorities. gml:name uses the gml:CodeType content model. The authority for a name is indicated by the value of its (optional) codeSpace attribute. The name may or may not be unique, as determined by the rules of the organization responsible for the codeSpace. In common usage there will be one name per authority, so a processing application may select the name from its preferred codeSpace.

`id` gmlBase-extract-v3_2_1.xsd:122 gml:id	`ID`	required	The attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.	`gml:AbstractGMLType`
