context_page_description: Generalised Enterprise Reference Architecture and Methodology is a generalised enterprise architecture framework for enterprise integration and business process engineering. It identifies the set of components recommended for use in enterprise engineering.
  This framework was developed in the 1990s by a joint task force of both the International Federation of Automatic Control and the International Federation of Information Processing on enterprise architectures for enterprise integration. The development started with the evaluation of then-existing frameworks for enterprise application integration, which was developed into an overall definition of a so-called "generalised architecture".
context_section_description: Generic Enterprise Reference Architecture (GERA) defines the enterprise related generic concepts recommended for use in enterprise integration projects. These concepts include life cycle; enterprise entity types, enterprise modelling with business process modelling; integrated model representation in different model views and modelling languages for different users of the enterprise architecture (business users, system designers, IT modelling specialists, among others).
