USING METAMODELS TO PROMOTE DATA INTEGRATION IN AN E-GOVERNMENT APPLICATION SCENARIO

摘要

The increasing popularization of Internet has created unprecedented expectations and promises when dealing with a more intelligent use of the available data. This use is based on metadata and on a new dimension of metadata modeling techniques. An initiative supported by OMG culminated in the current MOF -Meta-Object Facility specification, which is an open standard with facilities to definition and manipulation of metadata and metamodel. This paper describes a metadata management system that is based on the MOF specification and presents one usage of this system in an e-government scenario.
