Abstract: We present an integrated view of two information models developed at NIST and their use. The Core Product Model (CPM) provides a generic model of the artifact|s function, form and behaviour. The Open Assembly Model (OAM) defines a system level conceptual model of assemblies supporting tolerance and kinematics representation. The objectives of the paper are to: present recent extensions of the two models; explicitly link the two models; and propose CPM/OAM as the basis of a product information-modelling framework for Product Lifecycle Management (PLM). A case study illustrates the use of CPM/OAM for capturing information.

Keywords: product modelling; information modelling; data modelling; artifact; form; function; behaviour; entity-relationship data model; next-generation product development tools; core product model; product information; open assembly model; tolerance representation; kinematics representation; product lifecycle management; PLM.
