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.
