Standards for engineering information models

The nature of the information model and its language implications are discussed. The problem of managing the wide range of information modeling languages, the products of several public-domain efforts to produce such models, the criteria for evaluation, review, consensus and change, and the ownership of and credit for these models are addressed. Other issues to be addressed are the changes which result when models are integrated into a larger scope (e.g., electrical products as a part of electromechanical products), and the impact of semantics, of information entities on data dictionary standards
