Abstract

The session was chaired by Alan Burns who indicated that there had been several position papers received addressing various aspects of the Ravenscar Profile (RP). Based on the material presented in these papers, he suggested that the session consider the following topics:• Implementation and Application Experiences• Completing the Definition• Extending the ModelThe goal of the first topic was mainly to receive general feedback from the implementation teams and application programmers. These had resulted in several issues being raised. The RP only addresses issues relating to tasking; it is silent on all other aspects of the Ada language. However, some had felt that for a Ravenscar implementation to be effective, there were other restrictions that were necessary. These issues are reported under the second topic. Finally, there are many tasking profiles that could be defined. However, there had been no position papers making proposals for new subsets. Instead, papers had identified extensions to the RP that would give more expressive power but at little extra cost. These were discussed under the third topic. Issues to do with extending the RP for Distributed Systems were not considered in this session.
