A physics analytical entity is an abstraction of the real world created within the science of classical physics for the description of physical entities and the analysis of physical processes.
The OPB is an ontology of the abstract concepts created by the science of systems dynamics and thermodynamics. Aside from its dependence on classical physics, the OPB does not purport to be a philosophically-based representation of physical "reality". We are motivated by utilitarian goal of facilitating and expediting the annotation and cross-referencing of physics-based analytical models in the realm of biomedicine.
The OPB does not include quantum or relativistic physics, nor is it intended to recapitulate the axiomatic basis of physics as a theoretical framework. Whereas the foundational theory of the OPB encompasses both discrete systems analysis (using ordinary differential equations; ODEs) and continuum systems analysis (using partial differential equations; PDEs), the first version of the OPB is targeted solely to discrete systems analysis.
