The sources for topic map patterns I mentioned yesterday use a variety of modeling languages:
Domain-Driven Design: Tackling Complexity in the Heart of Software by Eric Evans. (Uses UML (Unified Modeling Language))
Although constraints will be expressed in TMCL, visually it looks to me like UML should be the notation of choice.
Will require transposition from non-UML notation but seems worthwhile to have a uniform notation.
Any strong reasons to use another notation?
