The Logical Framework Approach was developed in 1969 for the U.S. Agency for International Development (USAID). It is based on a worldwide study by Leon J. Rosenberg, a principal of Fry Consultants Inc. [1] In 1970 and 1971, USAID implemented the method in 30 country assistance programs under the guidance of Practical Concepts Incorporated, founded by Rosenberg.
In logic, a logical framework provides a means to define (or present) a logic as a signature in a higher-order type theory in such a way that provability of a formula in the original logic reduces to a type inhabitation problem in the framework type theory. [1] [2] This approach has been used successfully for (interactive) automated theorem ...
PERA Reference model: Decision-making and control hierarchy, 1992. Purdue Enterprise Reference Architecture (PERA), or the Purdue model, is a 1990s reference model for enterprise architecture, developed by Theodore J. Williams and members of the Industry-Purdue University Consortium for Computer Integrated Manufacturing.
Since they are used in various contexts and for different purposes, their typical components and levels of complexity varies in literature (compare for example the W.K. Kellogg Foundation [10] presentation of logic model, mainly aimed for evaluation, and the numerous types of logic models in the intervention mapping framework [11]). In addition ...
The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.

Twelf signatures can be executed via a search procedure. Its core is more sophisticated than Prolog, since it is higher-order and dependently typed, but it is restricted to pure operators: there is no cut or other extralogical operators (such as ones for performing I/O) as are often found in Prolog implementations, which may make it less well-suited for practical logic programming applications.
