Domain-Specific Meta-Model Extensions and Meta-Data Management in Repository Systems

Stefan Jablonski, Ilia Petrov

Building applications in a flexible and extensible manner is a key requirement in a database envi- ronment. We argue that adaptability and extensibility can be guaranteed by the utilizing the con- cepts meta-modeling, notion building and reflection, which require the use of repositories. We pre- sent an approach, in which domain knowledge and meta-framework are combined to produce ex- tended meta-schema. This combination facilitates application design. We show how the extended meta-schemata can be deployed into a repository and thus enforce structural consistency on object- level models and discuss how reflection techniques can be used to create meta-aware application programs.
