                            CHARTER OF ASISWG

The purpose of this working group is to develop and participate in
standardizing an implementation independent application programming
interface to allow retrieval of the information stored within an Ada
compiler's compilation database.

The initial goal of the working group was to further develop and
promote the Ada Semantic Interface Specification (ASIS) for Ada 83.
ASIS Version 1 is now complete and in the public domain. The working
group is currently developing ASIS for Ada 9X, and will work towards
its adoption as an international standard.

Membership in the working group is open to any interested party.

Current members include representatives of Ada compiler vendors, CASE
tool developers, application developers, and other users.

Members are responsible for their own expenses.

ASIS defines a vendor independent interface for accessing both the
syntactic and semantic information stored within an Ada compiler's
library for an Ada compilation unit, including the information relating
independently compiled units.  The definition and operational semantics
of ASIS are specified using Ada packages, with supporting commentary to
describe the semantics and usage of operations.  The Ada package
specifications that compose ASIS are in the public domain, and each
ASIS vendor is expected to provide a compliant implementation.
