[..] I view ontologies and rules as the basic building blocks for addressing this problem: ontologies can define declarative relationships between models, and rules can define operational conversion between models. However, in spite of the fact that we've had ontologies and rules for many years, I think this field is still in its infancy in terms of having strong patterns and convenient languages for using them with RDF to easily navigate between modeling levels. "Levels" is not quite the right word though, because different models form a network, not a single hierarchy. Interestingly this is reminiscent of a “reverse” version of _knowledge-driven_ activity recognition – one is given a series of low-level atomic actions, objects being manipulated, locations, and temporal relations between them (e.g., sequential); then, ontology-based reasoning is applied to infer higher-level activities (E-> A, instead of A->E) [1-4] William [1] L.
