At the Q.5/SG10 meeting in Geneva, April 28 - 06 May 1997, on the use of
SDL for the formalisation of behaviour in GDMO, there were no contributions
backed by substantial user requests. GDMO has been extended with a formalism
for expressing behaviour (GDMO+), and this proposal is out for ballot. With
this in mind, the Q.5/SG10 meeting would like to know if there is still any
need for SDL specified behaviour.
The meeting briefly discussed the GDMO+ proposal. It was not obvious from
this if GDMO+ can be used as the basis for implementation or if it is just
useful for conformance testing. The proposals being around for behaviour in
SDL has taken the approaches that the SDL specifications could be used as
the basis for implementation.
An eventual continuation of work with SDL specified behaviour of GDMO can
have two different directions:
1. provide guidelines on how to design/implement in SDL based on GDMO
specifications - this is for developers that have an established SDL
development environment and have to implement systems based on GDMO
2. provide a tight integration, with object models described in GDMO and
behaviour in a set of primitives for manipulation GDMO objects with and
with a subset of SDL, so that tool support can be obtained.
If you are a user of SDL that have any of these needs or if you happen to
be a GDMO user that also would like to get support for the implementation
part via SDL, please let us know. You may also forward your wishes/request
to your GDMO and/or SDL tool supplier, if any.
