Re: [opencsa-ms] SCA TC Liaison issues
Anish,

Thanks for bringing these items forward.

I have a suggestion of how to deal with
these items and similar items in the short run.  I suspect

that what I suggest will form part of
the long run process anyway.

These items should be placed onto the
Agenda of upcoming meetings of each TC by the chair(s)

of those TCs, with the aim of getting
each TC to make a decision.  In order to do this, each item must

be couched in terms of a definitive
recommendation that can be adopted.

Issue 2 below is in the right form.

Issue 1 below is more of a discussion.
 Here is a proposal:

-------

Issue 1: What should be the version
of the SCA specs?

To avoid confusion, all the initial
specifications produced by the SCA TCs belonging to the Open CSA MS

will be given the label "Version
1.1".

This will enable all the specifications
to be clearly related to each other and also to be distinguished from

the Version 1.0 SCA specifications published
by the Open SOA collaboration in March 2007.

-------

Now all that is required is to get each
TC to adopt the resolution for each of these issues.

The real liaison will begin if and when
TCs disagree about the resolution  ;-)

Yours,  Mike.

[opencsa-ms] SCA TC Liaison issues

Open CSA SC,

The SCA BPEL TC has two issues, which were discussed during the recently

concluded F2F, that require coordination across all SCA TCs. Since there

is no official liaison mechanism set up, on behalf of SCA BPEL TC I'm 

bringing these issues to the attention of the Open CSA SC. I would like

to request the SC to coordinate this across all the SCA TCs.

Issue 1: What should be the version of the SCA specs?

Should the version of the SCA specs be 2.0 or 1.x? Or something else?

It is certainly possible to have the assembly specification be version

2.0 and BPEL C&I specification version that depends on assembly 2.0
be 

1.5, for example. But such version numbers will be very confusing. Given

that the TCs are affiliated with the Open CSA MS, a better approach 

would be to have the same version number for all the initial output 

specifications of the various SCA TC. If not, at the very least, have 

the number before the "." be the same. This will require coordination

and agreement across all the TCs.

Issue 2: Use of RFC 2119 keywords in the spec

In aligning the spec with the OASIS template and accepting the OASIS TAB

recommendations, the SCA BPEL TC decided to use the RFC 2119 keywords 

along with the following restriction:

a) All RFC 2119 keywords will be of the uppercase form (for example, RFC

2119 keywords MUST be capitalized)

b) use of lowercase 2119 keywords will not be used in the spec. When the

use of 2119 keyword is needed, without having the implications wrt 

conformance, a suitable synonym will be found.

c) RFC 2119 defines keywords that are synonyms of each other. For 

example 'SHALL' and 'MUST' mean the same thing. The TC decided to not 

use multiple forms to mean the same. Therefore the TC decided to use 

'MUST' instead of 'SHALL' and 'MUST NOT' instead of 'SHALL NOT' through

out the spec.

Please note that the use of RFC 2119 keywords affect conformance. 

Consistency across the SCA spec with respect to conformance and the use

of normative conformance lanaguage is highly desirable.

Please let me know if you have any questions.

Thanks and regards.
