In mathematics, computer science, and operations research, mathematical optimization is the process of finding best feasible values (oftentimes maxima or minima) of a given objective that is modeled mathematically. This paper introduces the concept of a metamodel for optimization problems and describes an exploratory implementation of such a metamodel. The metamodel is (1) a conceptual model for capturing, in abstract terms, essential characteristics of a given optimization problem, and (2) a schema of sufficient formality to enable the problem modeled to be serialized to statements in a concrete optimization language. The exploratory metamodel presented in this paper addresses a majority of abstractions found in the OPL language. We present prototype software to compile OPL programs to populations of the metamodel and to serialize these populations back to OPL code. The paper describes the motivation for this work and a detailed specification of the exploratory implementation.
