The SCA Assembly technical committee
thanks Siemens for its comments on the SCA Assembly Model specification,
as contained in:
http://lists.oasis-open.org/archives/sca-assembly-comment/200906/msg00003.html
The Assembly technical committee took
a decision at its Face-to-Face meeting in December 2009 to take no action
in response to the Siemens comments,
with the result that the relevant parts of the specification are left unchanged.
The Assembly TC debated the points made
by Siemens about conformance and the requirement for a runtime to
implement at least one of the implementation
types standardized at OASIS at some length, with a variety of ideas being
considered. However, the committee was
unable to agree on an alternative approach to the question of conformance
which
did not have the effect of making "conformance
to the SCA Assembly specification" a rather meaningless statement.
As a result, the SCA Assembly specification,
version 1.1 has conformance that is tied to the use of at least one of
the implementation types standardized
at OASIS and which is also tied to the test suite available at OASIS.
The Assembly TC remains open to loosening
the conformance requirements in a future release of the SCA Assembly
specification and welcomes input from
Siemens and other parties who have useful ideas in this area. One
significant problem that was debated
at length is how an OASIS TC can lay down meaningful criteria for some
future implementation type that does
not get standardized at OASIS and require that those criteria are met for
any
conforming runtime. A similar
associated problem exists for the Test Suite, since although the Assembly
test suite is
carefully structured to be as independent
of implementation type as possible and is also easily adaptable to a new
implementation type, an executable version
of the test suite inevitably involves at least one implementation type
-
ensuring that a valid test suite exists
when using that new implementation type has proved particularly problematic,
since passing the test suite is one
of the conformance requirements.
Yours, Mike.
