Ontology integration carries significant importance in terms of reuse of knowledge and interoperability. In this paper, a framework for ontology integration based on extended metadata registry plus (XMDR+) is focused, that is, we try to developer a methods for ontology integration to provide high quality Semantic Web services. To sum up, the ontology integration framework proposed herein not only produces global ontologies; but also defines such methods, and, thereby, performs better in extending and integrating ontologies. The framework will rely on a model independent of ontology storage structures, but will be capable of representing semantic relationships between different ontology systems.
