Metadata Mediator
Home Up

 

The Metadata Mediator research project has three primary goals:

creating a Web-based "mediator" utility for translating models to and from XMI
prototyping a vendor independent XML representation for business rules
UML extensions for integrating rules into the methodology and model repository

For integration with UML, we are building on the proposed XML Metadata Interchange (XMI) standard that includes a full XML representation for UML. We have created an on-line demo that shows an XML rule representation integrated with an XMI object representation, all presented as dynamic, hyperlinked Web pages. The demo includes a detailed introduction and several examples.
