Technical Report, was published by Robert Barta at 2003-04-23

This report deals with some issues with the AsTMa= Language.

AsTMa= has been specified as a shorthand notation for Topic Map data. It was not meant as a substitute for XTM, the only official notation, as it only implements a particular subset of the concepts. Still, AsTMa= has proven useful over the years as quite a few maps have been created with. Most of these experiences flowed back into the language design.

In the following we pick up some issues with language itself; they might be simply a rationale why particular features are implemented they way they are, or a justification why specific Topic Map construct where not respected at all.

Topic Maps offered the semantic flexibility that I needed in Topincs, an application with an unlimited domain. It allowed me to make statements about any subjects. Exactly what I was looking for.
