scope:

This standard includes an abstract interface to services used by CASE tools. This interface will insulate a tool that uses a service from the provider of the service. The standard focuses on:

- Defining specific messages with their abstract parameters;

- Message semantics;

- Message sequencing (constraints on message ordering);

- Messages for Computer Aided Software Engineering domain.

The standard does not address:

- Definition of tool data (data integration);

- How the tool data are displayed (presentation integration);

- Language bindings of application program interface (interface syntax);

- How the message gets from one place to another (message communication protocol definition).

It is recognized that the messages and their parameters reflect some notion of the tool data.
