- integrate well into AsTMa*
- retrieval and content construction processor
- allows to phrase larger, more complex queries
- better opportunities for global optimization, than if application would try it
- means that the language needs a minimum of processing capabilities (if, loop, exceptions)
- be embeddable into web application servers
- normal retrieval language like SQL, XQuery (return simple values)
- XML application servers, XML pipelines, taglibs (return XML fragments)
- also as stand-alone ontology transformator
- like XSLT for XML, transform maps between two different ontologies (return TM content)
- allow to use typing
- typing as in low-level types: AsTMa? does not do this (yet)
- typing as in "using ontological information"
- keep expressitivity of the language down, formal tractabillity
