gml:RelatedTimeType

gml:RelatedTimeType provides a content model for indicating the relative position of an arbitrary member of the substitution group whose head is gml:AbstractTimePrimitive. It extends the generic gml:TimePrimitivePropertyType with an XML attribute relativePosition, whose value is selected from the set of 13 temporal relationships identified by Allen (1983)

gml:TimeInstantgml:TimeInstant acts as a zero-dimensional geometric primitive that represents an identifiable position in time.
gml:TimePeriodgml:TimePeriod acts as a one-dimensional geometric primitive that represents an identifiable extent in time. The location in of a gml:TimePeriod is described by the temporal positions of the instants at which it begins and ends. The length of the period is equal to the temporal distance between the two bounding temporal positions. Both beginning and end may be described in terms of their direct position using gml:TimePositionType which is an XML Schema simple content type, or by reference to an indentifiable time instant using gml:TimeInstantPropertyType. Alternatively a limit of a gml:TimePeriod may use the conventional GML property model to make a reference to a time instant described elsewhere, or a limit may be indicated as a direct position.
from subst. group gml:AbstractTimeTopologyPrimitive
gml:TimeNodeA time node is a zero-dimensional topological primitive that represents an identifiable node in time (it is equivalent to a point in space). A node may act as the termination or initiation of any number of time edges. A time node may be realised as a geometry, its position, whose value is a time instant.
gml:TimeEdgeA time edge is a one-dimensional topological primitive. It is an open interval that starts and ends at a node. The edge may be realised as a geometry whose value is a time period.
