TMCL is designed to allow users to constrain any aspect of the topic map data model. TMCL adopts TMQL as a means to express both the topic map constructs to be constrained and topic map structures that must exist in order for the constraint to be met. TMCL defines TMCL-Schema and TMCL-Rule. TMCL-Schema provides a type based model of constraints. TMCL-Schema is defined in terms of a more abstract model TMCL-Model. TMCL-Rule provides a generlised model of constraint based on TMQL. For each langauge a model, semantics and syntax are defined.
Both TMCL-Rule\Schema define sets of constraints. In general these constraints consist of terms that identify parts of the Topic Map to be constrained and terms that define the predicate or truth that must hold for the Topic Map to be considered to be consistent.

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.
