This Standard defines TMRM (Topic Maps Reference Model), which is more abstract and has fewer ontological commitments. Its purpose is to serve as a minimal, conceptual foundation for subject-centric data models such as the TMDM, and to supply ontologically neutral terminology for disclosing these. It defines what is required to enable the mapping of different subject-centric data models together to meet the overall goal of the Topic Maps standards, that each subject has a single location for all the information about it.

TMRM also provides a formal foundation for related Topic Maps standards such as ISO/IEC
18048 Topic Maps Query Language (TMQL) and ISO/IEC 19756 Topic Maps Constraint Language (TMCL).

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.
