Abstract
Metadata repository systems manage metadata typically represented as models or meta-models. In order to facilitate repository application development a dedicated query language, addressing the specific capabilities of such systems is required. This paper introduces a declarative query language for querying OMG MOF-based metadata repository systems called mSQL (meta-SQL). Some of the key features of mSQL are: support for higher order queries and model independent querying, unified handling of repository data and metadata, quantification over repository model elements, SQL-alignment. Some of the areas where mSQL may be applied are: querying schematically disparate models in MOF repositories; metadata application development; generic browsing of complex meta-data data collections; and ultimately Model-Driven Development.
