  abstract =     "This chapter studies an approach to establish a formal
                  connection between data models, in particular between
                  conceptual data models and implementation data models. We
                  use metamodeling techniques based on the Meta Object
                  Facility MOF. MOF may be regarded as a subset of the
                  Unified Modeling Language UML. As prominent example data
                  models, we formally describe and thereby analyze the
                  Entity-Relationship and the Relational data model. In
                  addition, we represent the transformation between these
                  data models by MOF language features. Thus we describe
                  the data models and their transformation within a single
                  framework. All results are formally represented and
                  validated by a MOF compliant tool. The approach presented
                  is general enough so that it can used for other data
                  models being important for the Semantic Web, e.g., the
                  object-oriented data model or semi-structured data models
                  like XML-based models.",
