The TM_TemporalPosition shall be associated with a single temporal reference system, as specified in 5.3. An instance of TM_Instant is an identifiable object, while an instance of TM_TemporalP
8、osition is a data value. The TM_TemporalPosition of a given TM_Instant may be replaced by an equivalent TM_TemporalPosition associated with a different temporal reference system.

14、ps to other topological primitives within a topological complex. The two topological primitives relevant for temporal information are the node, which is 0-dimensional, and the edge, which is 1-dimensional. In the temporal schema, they are represented by two subclasses of TM_TopologicalPrimitive: TM_
15、Node and TM_Edge (Figure 6). When an application includes information about temporal position as well as connectivity, a TM_TopologicalPrimitive may be associated with a TM_GeometricPrimitive of the same dimension. Because topological primitives are intended to provide information about connectivity
16、, their most significant characteristics are the associations that link them to each other. Another consequence is the requirement that every TM_TopologicalPrimitive shall be a member of one and only one TM_TopologicalComplex. Page 17, subclause 5.3.1 Replace 5.3.1 b) with the following: b) domainOf
17、Validity:EX_Extent shall identify the space and time within which the TM_ReferenceSystem is applicable. The data type EX_Extent is specified in ISO/TS 19103. It permits a description of both spatial and temporal extent. This attribute shall be used whenever an application schema includes TM_Temporal
18、Positions referenced to a TM_ReferenceSystem which has a valid extent that is less than the extent of a data set containing such values.

20、2 illustrates an alternative way of using a TM_GeometricPrimitive for a temporal feature attribute. In this case, the feature attribute periodOfOccupancy is represented as a UML class that is linked to Building by a UML association. PeriodOfOccupancy is a subtype of TM_Period. It inherits the associ
21、ation roles begin and end from TM_Period, but it restricts the data type in each case to DateTime. (At the TM_Period level, the data type for these attributes is TM_TemporalPosition.) It also inherits the interfaces TM_Order, from which it uses the operation relativePosition(other : TM_Primitive) :
22、TM_RelativePosition, and TM_Separation, from which it uses the operations length() : TM_Duration and distance (other : TM_GeometricPrimitive) : TM_Duration.
