Where can I get information on querying topic maps?
At the moment topic maps are so new that there is no standard method for querying them. Work has started within ISO to define a standard topic map query language called TMQL, based on a number of existing query languages.. While we are waiting for the TMQL standard, Ontopia has developed its own topic map query language called tolog, which has also been used as input to the TMQL process. See the following question for more information about tolog, and also the section on query languages on our learn more page.
