Title:
Evolving Ada Bindings and Ada APIs
Abstract:
A workshop was held at SIGAda 2002 to address the
management of Ada bindings and Application Program
Interfaces (APIs). The purpose of that workshop was to
identify a mechanism and begin to define a plan for the
management of APIs for Ada. ISO/WG9 has requested that
SIGAda and Ada-Europe propose such a mechanism for
managing Ada bindings that are not covered via formal
standards. Then ISO/WG9 can recommend these bindings
as *defacto* standards, thus providing a process to register,
and thus manage, bindings available to the Ada community
without the formalism required by ISO. This workshop was
well received at SIGAda 2002. There were many excellent
suggestions made to improve a draft plan to manage Ada
APIs.
Registered APIs are either Public or Private. Public APIs
are those where a dedicated team assumes the responsibility
for their maintenance and evolution. Changes are controlled
via a concensus-based process. Private APIs are those
developed and maintained by a third party. With permission
from the developer, these APIs are kept on the API web
page as a convenience to the user community. In both
cases, Useful artifacts will be provided on the API web
page, when available. Besides compilable APIs, there will
also be other valuable artifacts such as examples, tutorials,
known problems, lessons learned, etc.
A major topic of discussion at the workshop was the
Management of both registered public and registered private
APIs. There are many issues associated with each. It is
proposed that a SIGAda API Working Group be responsible
for this activity.
The workshop was extremely well received. The
presentation on Thursday night will provide a summary of
the workshop. Plans are already underway to implement
this management plan. We are initially planning to use the
Common Gateway Interface (CGI) as a test case for the
procedures to manage Ada APIs. There will be other
bindings of potential near term interest as well. Besides the
CGI Bindings, other interfaces to which we have had recent
presentations include: Windows Graphical User Interfaces
and Hierarchical Data Format (HDF). This presentation
could be valuable to all users of Ada bindings. Those
interested in getting involved are especially welcome.

over two decades and with various working groups of
SIGAda, including the Ada Bindings Working Group
(ABWG) and the ASIS Working Group (ASISWG). He has
been using World Wide Web technologies since the early
1990s to communicate effectively for international
standardization efforts.
