||A meta-topology for product modeling
||A major issue in product modeling is the integration of two essentiallydifferent modeling approaches: the top-down functional-orientedapproach, and the bottom-up technical-oriented approach.The ISO-STEP General AEC Reference Model (GARM) supports thisdual design principle around the kernel entities Functional Unit andTechnical Solution.During the development of GARM a number of topology related issueswere encountered. To mention two main issues:- How to structure a functional network to be consistent overseveral decomposition/aggregation levels, as well as over thebranches of the hierarchical tree?- How to relate this network and the multiple coexistingrepresentations which share this same kernel?Both issues can be addressed, in principle, using a pure topologyindependent network and an intermediate layer to relate thedependent representations.This intermediate layer is called: Meta-Topology.
