RFD-based distributed functional part specifications for the facilitation of service-based architecture

In this paper we highlight research and development that is done in the larger context of a service ori-ented architecture framework for the support of design decisions. We are going to illustrate how methods that adhere to the "open world assumption" (OWA) can be used to construct semantically meaningful information fragments from larger models. We are demonstrating the composition and use of Functional Parts specifications as RDFS graph pat-terns. We outline a prototype that applies RDF(S) sub graph extraction and merging with queries and rules in distrib-uted scenarios using models based on the IFCs that have been notated as partitioned OWL models. We are showing how these sub graphs can be used as machine-readable information exchange requirements not only for existing models but also for the semi-automated integration of newly added conceptual models as project-specific augmentations.
