We present a framework for semantic web applications based on constraint interchange and processing.At the core of the framework is a well-established semantic data model (P/FDM)with an associated expressive constraint language(Colan).To allow data instances to be transported across a network, we map our data model to the RDF Schema specification.To allow constraints to be transported, we define a Constraint Interchange Format(CIF) in the form of an RDF Schema for Colan, allowing each constraint to be defined as a resource in its own right.We show that, because Colan is essentially a syntactically-sugared form of first-order logic, and P/FDM is based on the widely used extended ER model, our CIF is actually very widely applicable and reusable.Finally, we outline a set of services for constraint fusion and solving, which are particularly applicable to business-to-business e-commerce applications.These services are accessible using the CIF.
