1 Scope The CDIF family of International Standards is primarily designed to be used as a description of a mechanism for transferring information between modelling tools. It facilitates a successful transfer when the authors of the importing and exporting tools have nothing in common except an agreement to conform to CDIF. The language that is defined for the transfer format also has applicability as a general language for import/export from repositories. The CDIF semantic metamodel defined for CASE also has applicability as the basis of standard definitions for use in repositories. The International Standards which form the complete family of CDIF standards are documented in ISO/IEC 15474‑1. These International Standards cover the overall framework, the transfer format and the CDIF semantic metamodel. Figure 1 — CDIF family of International Standards The diagram in Figure 1 depicts the various International Standards that comprise the CDIF family of standards. The shaded box depicts this Standard and its position in the CDIF family of standards. This International Standard defines the portion of the CDIF semantic metamodel that supports general Data Modelling. This includes Entity-Relationship-Attribute Modelling as well as Logical Database Design.
