This paper describes a query language for topic maps called tolog. This query language is inspired by Prolog and, as described in this paper, supports everything described in the requirements for the ISO topic map query language TMQL. It has a clear and simple syntax, and its basic features are easy to implement.

This paper describes the language as implemented, extensions to make it serve as a full TMQL, explores possible uses of it, and discusses implementation considerations.

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.
