Introduction, was published by Robert Barta at 2005-05-26

This document gives an overview over the AsTMa* language family.

To address some aspects of knowledge engineering with Topic Maps, the AsTMa* language family was created. The objective was to define a set of notations within one common concept framework and with a common mindset. This should provide all involved parties to have a migration path from topic map authoring up to transforming ontologies.

This common framework also makes it easier to provide a consistent underlying formalism and to define a coherent semantics on language constructs. In that the AsTMa* way of topic mapping will hopefully have few alignment problems between the individual sublanguages.

These sublanguages themselves are embedded within each other: the authoring notation AsTMa= is used by the constraint language AsTMa! and that, in turn, is part of AsTMa?, the querying and retrieval language. The fourth language AsTMa+ for updates is only available as idea-ware, so it cannot be discussed in great detail.

Topic Maps offers an information architecture for semantic portals with
highly networked content and access paths in support of the associative
human mind. It is our technology of choice for knowledge oriented
application systems.
