Constraints Analysis With Respect To BFG Metadata Creation FINAL MSc Thesis 2005

The BFG is a tool for the development of coupled models created by the University of Manchester that reads XML documents to obtain configuration data. The XML documents contain complex relationships termed ‘constraints’ that, if not expressed correctly, can cause errors in the execution of BFG and the coupled models generated by the BFG technology. The research in this thesis is focussed around an analysis of constraints with respect to BFG metadata creation. It shows how current XML validation technology falls short of meeting all the design goals of a BFG metadata constraint checking solution. A new approach is suggested and implemented, leveraging the power of Object Constraint Language. Finally, the new approach is integrated into a graphical user interface for BFG metadata creation also developed by the University of Manchester.
