ABSTRACT
The semantic web is supposed to be a global, machine-readable information re-
pository, but there is no agreement on a mon information metamodel.
To prevent the fragmentation of this nascent semantic web, this thesis introduces
the expressive and flexible Braque metamodel. Based on non-well-founded par-
tially ordered multisets (hyper pomsets), augment with a powerful reflection
mechanism, the metamodel supports the automated, lossless, semantically trans-
parent integration of relationship-based metamodels. Complete mappings to
Braque from the Extensible Markup Language (XML), the Resource Description
Framework (RDF), and the Topic Maps standard are provided. The mappings
place information at the same semantic level, allowing uniform navigation and
queries without regard for the original model boundaries.
