Revision of the combined metamodel

To enable ontologies to leverage model-driven software development and other software processes, a conceptual integration of the ontology and the model-driven software development paradigm must take place. To achieve such an integration, the deliverable ful lls the requirement of an integrated metalanguage on level M3, as well as consistently de ned, integrating metamodels on level M2 to connect ontologies to the model-driven software development model chain. Based on experiences collected with the initial prototype the joint metamodel, its querying and its transformation, we revise the patterns identi ed in previous deliverables. In contrast to our rst deliverable D1.1 we mainly concentrate on the user scenarios and the languages which are used in the case studies.
