gml:TopoCurveType
Complex type information
Namespace: http://www.opengis.net/gml/3.2
Schema document: external/ogc/gml/3.2.1/topology.xsd
Content
- Sequence [1..1]
- gml:metaDataProperty [0..*] deprecated
- gml:description [0..1] The value of this property is a text description of the object. gml:description uses gml:StringOrRefType as its content model, so it may contain a simple text string content, or carry a reference to an external description. The use of gml:description to reference an external description has been deprecated and replaced by the gml:descriptionReference property.
- gml:descriptionReference [0..1] 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:identifier [0..1] 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:name [0..*] 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.
- gml:directedEdge [1..*] A gml:directedEdge property element describes the boundary of topology faces, the coBoundary of topology nodes and is used in the support of topological line features via the gml:TopoCurve expression, see below. The orientation attribute of type gml:SignType expresses the sense in which the included edge is used, i.e. forward or reverse.
