Element information

Content

• Sequence [1..1]
  from type gml:AbstractGMLType
  from group gml:StandardObjectProperties
  gml:metaDataProperty [0..*]    Contains or refers to a metadata package that contains metadata properties.
  gml:description [0..1]    Contains a simple text description of the object, or refers to an external description.
  Choice [0..*]
  from subst. group gml:name
  gml:name    Label for the object, normally a descriptive name. An object may have several names, typically assigned by different authorities. 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.
  gml:csName    The name by which this coordinate system is identified.
  gml:coordinateOperationName    The name by which this coordinate operation is identified.
  gml:methodName    The name by which this operation method is identified.
  gml:parameterName    The name by which this operation parameter is identified.
  gml:groupName    The name by which this operation parameter group is identified.
  gml:datumName    The name by which this datum is identified.
  gml:meridianName    The name by which this prime meridian is identified. The meridianName most common value is Greenwich, and that value shall be used when the greenwichLongitude value is zero.
  gml:ellipsoidName    The name by which this ellipsoid is identified.
  gml:srsName    The name by which this reference system is identified.
  from type gml:AbstractTimePrimitiveType
  gml:relatedTime [0..*]    
  1. Choice [1..1]
     • gml:beginPosition    
     • gml:begin    
  2. Choice [1..1]
     • gml:endPosition    
     • gml:end    
  from group gml:timeLength
  Choice [0..1]
  • gml:duration     This element is an instance of the primitive xsd:duration simple type to enable use of the ISO 8601 syntax for temporal length (e.g. P5DT4H30M). It is a valid subtype of TimeDurationType according to section 3.14.6, rule 2.2.4 in XML Schema, Part 1.
  • gml:timeInterval     This element is a valid subtype of TimeDurationType according to section 3.14.6, rule 2.2.4 in XML Schema, Part 1.
