-When OGC standards involve time, they generally refer to the ISO documents such as <<iso19108>> (now largely superseded), <<iso19111>>, <<iso8601>>, and their freely available OGC equivalents, such as <<ogc18005>> (the equivalent to <<iso19111>>).
+When OGC Standards involve time, they generally refer to the ISO documents such as Geographic information Temporal schema <<iso19108>> (now largely superseded), Geographic information Referencing by coordinates <<iso19111>>, Date and Time Format <<iso8601>>, and their freely available OGC equivalents, such as OGC Abstract Specification Topic 2: Referencing by coordinates  <<ogc18005>> (the equivalent to <<iso19111>>).
 
-Much effort over decades has gone into establishing complex structures to represent calendar based time, such as the <<iso8601>> notation, and many date-time schemas. A consequence of this effort is that many end-users and developers of software use calendar based "coordinates", with the associated ambiguities about underlying algorithms, imprecision and inappropriate scope.

-The aim of this Abstract Specification is to establish clear concepts and terminology, so that people are well aware of the advantages and disadvantages of adopting a particular technological approach to time and then perhaps build better, more appropriate, interoperable systems for their use cases.
