Constraining Topic Map™ instances is a necessary component of TM engineering. To make these constraints explicit we propose a Topic Map Constraint Language, AsTMa!. As such, AsTMa! is a part of the AsTMa language family which was designed to facilitate authoring, but also constraining and querying topic maps. This document provides a semi-formal definition of the language. Note that this is still an evolving project and that this document is a current snapshot only.
