Knowledge representation and the dimensions of a multi-model relationship

The exchange of data between different models in a multi-simulation environment is about the exchange of information from within the context of two separate worldviews. This amounts to knowledge (information in context). To represent this knowledge, in any of a number of different ways (meta-data, ontological reference, frames, etc.) there must be a method to bridge the gap between what the worldview of origination can represent and what the worldview of destination can receive. This requires some understanding of the dimensions of difference between the two worldviews. As each separate model is the product of a different perspective by the model's developer, each individual model will have a different worldview. Understanding what these differences are, and viewing them in light of the requirements for conceptual interoperability will contribute a great teal to the knowledge that must be captured for meaningful exchange.
