CTM writer

Project category: Utilities and Components
Project status: Productive


This implementation of a CTM Writer provides the core functionality of exporting every topic map to CTM. The main benefits of the CTM writer are:

  • The code of the CTM writer is completely open source and can be modified
  • The CTM writer works on top of the TMAPI and is independent of the real topic map engine implementation ( works with Ontopia, tinyTim etc. )
  • The CTM writer supports the partial serialization of topic map fragments ( topics, associations etc. )
  • The CTM writer supports additional features like prefix- and template-detection



is associated with {{count}} items.


CTM is the abbreviation for Topic Maps Compact Syntax. CTM is defined by ISO 13250-6, that is, part 6 of the Topic Maps standard. It’s a textual notation to describe topic maps.

As a former information scientist, I am fascinated since 1999 by the capabilities for building Topic Maps-based knowledge systems having the potential to augment human mind. One can model arbitrary knowledge organization systems, deal with semantic heterogeneity, collocate all facts about one subject in one logical place, and with TMQL have semantic retrieval on federated semantic networks. Therefore I expect bright prospects for business concepts building on the exchange of such knowledge snippets via semantic knowledge services.
