This report describes the Compact Topic Maps Syntax (CTM).

External Link: more information

CTM (Compact Topic Maps) is a text-based notation for representing topic maps. It provides a simple, lightweight notation that complements the existing XML-based interchange syntax defined in [XTM] and can be used for manually authoring topic maps; providing human-readable examples in documents and serving as a common syntactic basis for TMCL and TMQL.

The principal design criteria of CTM are compactness, ease of human authoring, and maximum readability. CTM supports all constructs of the [TMDM], except item identifiers on constructs that are not topics.

This part of ISO/IEC13250 should be read in conjunction with [TMDM] since the interpretation of the CTM syntax is defined through a mapping from the syntax to the data model there defined.

The idea of Topic Maps is essential to enable dynamic information logistic. This requires a system that understands the context of the user to provide relevant informations and options automatically. Therefore semantic analysis is needed organizing content in a dynamic net structure.
