Technical Report, was published by Dmitry Bogachev, Lars Heuer, and Gabriel Hopmans at 2008-05-15

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.

Topic Maps is an excellent paradigm to support human thinking and to visualize networked information. As part of my PhD project, I therefore chose Topic Maps as the conceptual foundation for designing and implementing a software prototype for semantic knowledge retrieval.
