General-Purpose Modeling (GPM) is the systematic use of a General-Purpose modeling language to represent the various facets of an object or a system. Examples of GPM languages are:
- - the Unified Modeling Language (UML), an industry standard for modeling software-intensive systems,
- - EXPRESS (ISO 10303-11), an international standard for the specification of data models,
- - IDEF, a group of languages from the 1970s that aimed to be neutral, generic and reusable,
- - Gellish, an industry standard natural language oriented modeling language for storage and exchange of data and knowledge, published in 2005.
- - LISP, a functional programming language designed for symbol processing (later extended with imperative abilities)
- - XML, a data modeling language now beginning to be used to model code (MetaL, Microsoft .Net )
Contrast GPM languages with dedicated Domain-Specific Modeling (DSM) languages, which like Domain-Specific Languages (DSLs), are maturing and becoming a viable alternative to GPM languages.
