ASIS is an open and published callable interface which gives CASE tool and application developers access to this information. ASIS has been designed to be independent of underlying Ada environment implementations, thus supporting portability of software engineering tools while relieving tool developers from needing to understand the complexities of an Ada environment's proprietary internal representation. The working group is currently developing ASIS for Ada 95, and is working towards its adoption as an international standard. The working group successfully developed ASIS for Ada 83, which is now complete and in the public domain. Membership in the working group is open to any interested party.
Members are responsible for their own expenses.
Current members include representatives of Ada compiler implementors, CASE tool developers, application developers, and other interested users.
