The temporal topology schema for ISO19136 provides constructs for handling topological complexes and temporal feature relationships. Temporal geometric characteristics of features are represented as instants and periods. While, temporal context of features that does not relate to the position of time is described as connectivity relationships among instants and periods. These relationships are called temporal topology as they do not change in time, as long as the direction of time does not change. It is used effectively in the case of describing a family tree expressing evolution of species, an ecological cycle, a lineage of lands or buildings, or a history of separation and merger of administrative boundaries.This schema reflects a partial yet consistent implementation of the model described in ISO 19108:2002.GML is an OGC Standard.Copyright (c) 2001,2005,2010 Open Geospatial Consortium.To obtain additional rights of use, visit http://www.opengeospatial.org/legal/ .

Annotations
"TimeNode" is a zero dimensional temporal topology primitive, expresses a position in topological time, and is a start and an end of time edge, which represents states of time.Time node may be isolated. However, it cannot describe the ordering relationships with other primitives. An isolated node may not be an element of any temporal topology complex.
Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods. This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
