The author of this paper presents the results of an effort started in 1987, aimed at developing a standard data model created with computer-aided software engineering (CASE) tools to ease the interchange among different tools.
The standard provided, Electronic Industries Association/CASE Data Interchange Format (EIA/CDIF), is explained in the paper, starting with its four-layer architecture, with a special emphasis on the upper level, called M3 (EIA/CDIF meta-metamodel). The paper ends with an example of a metamodel definition using EIA/CDIF syntax.
The main contribution of the paper is that it provides readers with a very detailed description of the standard developed. However, depending on the reader, this could be a drawback, since, from my viewpoint, the paper could not be easy to read for subjects who are non-experts on the topic.
I would like to note the complete standards reference section in the paper.
