| 1. A method of creating models of alternative physical representations of one or more entities, each alternative physical
representation corresponding to a wire format, the alternative physical representations facilitating conversions from one
wire format to another, the method comprising:
creating a meta-model for defining entity models, the meta-model including a logical meta-model and a physical meta-model,
the logical meta-model defining a logical model describing a logical structure of the one or more entities in a platform and
programming language neutral manner wherein said logical meta-model comprises logical entity component classes representing
logical entity components, and the physical meta-model defining a physical model describing a plurality of alternative physical
representations of the one or more entities whose logical structure is described in the logical model, said physical meta-model
comprising base classes which represent wire format neutral physical entity components corresponding to said logical entity
components, and further comprising correspondence associations between said logical entity component classes and said corresponding
base classes wherein said physical meta-model comprises a mapper class for representing said correspondence associations,
said mapper class having a first association with a logical entity component class and a second association with a corresponding
base class; and
creating the plurality of alternative physical representations.
