This CEN Report is a Statement of Requirements. The Report describes a reference model and then details requirements for Enterprise Model Execution and Integration Services (EMEIS) expressed in terms of that model.This CEN Report also stands as an introduction to the comparison CEN Report on CIM Systems Architecture: Enterprise Model Execution and Integration Services: Evaluation Report by setting out necessary concepts, the relationships between these and the requirements for the services which are needed to support integration and execution of enterprise models and models components.In accordance with the mandate reproduced as Annex A, this report is concerned with:- The "collection and evaluation of existing separate initiatives on Framework for ...Enterpise Model Execution and Integration Services" for the execution of enterprise models specific to CIM and model components.- "As a requirement, such initiatives shall be in line with the ENVs developed through Mandate BC-62 and with ENV 40 003".The enterprise model(s) have to support integration of physical components, integration of applications and information, and, at the highest level, integration of bussiness requirements. The use of such enterprise models requires supporting services, EMEIS.The overall requirement for the EMEIS is:- To support the execution of a model or model components for the day to day management of the enterprise, and - To support the embedding of theses model components into and within the supporting execution environment.Particular requirements for the EMEIS are currently foreseen as the ability to support:- On-going changes in the modus operandi of the enterprise,- Life-cycle concerns for models and model components,- Structures and objects composed of data of different kinds and from different sources,- Co-ordination of the structures and objects.
