Mechanized Reasoning Systems : a Preliminary Report ?

It is widely recognised that the integration of diierent (sub)-provers is a key issue in the construction of reasoning tools of practical usage. Unfortunately experience shows that eeective integration is very diicult to achieve. The Open Mechanized Reasoning Systems (OMRS) Project started in 1992 with the objective to design a formal framework for the speciication of state-of-the-art provers. The starting point of the OMRS approach is to structure the speciication of a system in a logic component, a control component, and an interaction component. Crisply separating the concerns of the three layers, results in clearer and better speciications. The paper provides an informal and preliminary report of the OMRS Project and brieey illustrates the application of the OMRS speciication framework to two challenge applications.
