RoKEx: Robust Application-layer Knowledge Exchange

Decisions in a dynamic environment may be based on information coming from a number of different knowledge sources described using different knowledge representation languages. This paper describes a common framework in which the data and rules, both static and dynamic, that may exist in disparate knowledge sources may be represented. We focus on two commonly used knowledge representation languages, namely SQL and OWL-DL. We have chosen these as examples because they make different assumptions about the knowledge they hold and we use them to show that our framework can represent knowledge under these different assumptions.
