One of the big challenges of public administration is the need to understand and evolve legacy systems for the purpose of documentation, improvement, modification, interoperability, porting, migrations, reuse, redesign and/or redeployment. There is a need for standardization in legacy transformation that will enable integration and interoperability between different solutions. The OMG has issued a request soliciting proposals for a metamodel to capture knowledge from legacy systems (referred to as the Legacy Knowledge). In this paper we examine how a MOF-based repository can support the definition, modeling, exchanging and integration of metamodels created for legacy knowledge discovery.
