Jeff,
I note that the Assembly TC had a considerable
debate on the Exit Criteria and did discuss the matters
that you raise in your email before
it took the vote to adopt the Exit Criteria. Words similar to the
ones
that you describe failed to win support
in the TC.
One point to make is that the SCA Assembly
specification does not in itself deal with interoperability -
this must instead be the province of
the Bindings TC.
Regarding Portability, I believe that
the requirements of Portability for SCA artifacts are met if an SCA
Runtime conforms to the SCA Assembly
specification, since that is essentially what the specification
is about.
I agree that when considering whether
the Exit Criteria have been met by two or more SCA runtimes,
members of the TC will want evidence
and assurance that those SCA runtimes do indeed conform to
the specification. However, I
think that this is an obvious point and it serves no purpose to add
words to the Exit Criteria. I
don't think that it is wise or necessary to be prescriptive about the evidence
that the TC will accept when considering
the claims relating to a given SCA runtime.
I agree that the Assembly Test Suite
is a fine piece of work and evidence of passing the tests will certainly
convince me that a runtime is conforming.
However, I do not wish to exclude other forms of convincing evidence
that may be presented relating to a
given SCA runtime.
Yours, Mike

Subject:
[sca-assembly] Exit Criteria Incomplete
hi,
I don't believe the TC has completed its job as required by the
Charter wrt Exit Criteria - though we certainly have made concrete
progress towards that goal.
The SCA Assembly Charter requires:
"The TC shall define concrete exit criteria that include at least
two
independent offerings that implement and are compliant with the all
normative portions of specifications and demonstrate interoperability
and portability as appropriate. Note that these are minimums and that
the TC is free to set more stringent criteria."
Last week the Assembly TC adopted exit criteria as follows:
The Concrete Exit Criteria for the SCA Assembly V1.1 specification are
that there shall be at least 2 independent SCA runtimes each of which
are compliant with all normative portions of the specification as
described in Section 12.2 of the SCA Assembly V1.1 specification
We have completed the first part and met the minimums required by the
Charter wrt number of offerings, but we have NOT YET set criteria for
the second part - "demonstrating interoperability and portability
as
appropriate".
I, and others, have struggled unsuccessfully so far, with words that
would be satisfactory. Nevertheless, the TC still needs to do that
before it can proceed to vote on whether those criteria have in fact
been met.
EXAMPLES might include such things as: The easiest thing in my mind is
demonstrate that the 2 impls pass the test suite with 100% (98% or 95%
or nnn%) success. Other examples might be provide output that shows
that 98.34% of TA's have been successfully tested. I'm sure there are
lots of other possibilities.
NOTE: Adopting those criteria is a different act from VOTING that
the criteria have been met. As we have discussed many, many times -
making that decision is a judgment that each voting member of the TC
will have to make when the time comes.
Also, please note that there is nothing in the above suggestions
as
to who does the demonstrating. It could be a the provider of the
offering. it could be another TC member. It could be an interested
third party.
cheers,
jeff
