Re: [wsia] [wsia-requirements][E907]

I think the intent here is to capture a significant reduction in network
overhead without a significant increase in complexity. Since this
requirement (even as you have rewritten it) could be accomplished either by
batching operation invocations (supported by all web service stacks?) or by
defining batch oriented operations, I think the intent can be accomplished.
I think the batching of dissimilar operations raises a lot of issues, some
of which will be out of the domain of this committee and therefore should
not be covered as a requirement (though we may want to drive the issues
onto the relevant standards committees).

As far as the expansion of this requirement involved in your rewrite, do we
want to require the create, update, delete AND read can all be done in a
single operation? Basically, does combining read and write create more
confusion than it is worth?

E907
      It should be possible for a Consumer to batch update multiple
      properties of the Producer with one invocations.

      Debate: GT, PQ, TC, SR, WC, RT.
      Debate whether this is true for all WSIA operations.

      I think the edit we came up with is fine, althought I also think that
      this *is* true for all (or most) WSIA operations.  The problem I have
      is that as requirements we may want to single out operations that can
      be performed in batch to simplify our scope.  All WSIA operations can
      be done in batch, but this may be to complex a specification for rev
      1.  I imagine there might be some more complex state management if
      getMarkup() or invokeAction() were able to be invoked in batch.
      Therefore, I propose that we might want to keep this requirement for
      only properties at this time.  I would expand the requirement (or add
      more reqs) to encompass reading properties and performing updates and
      reads along with other operations (for example, getMarkup() or
      invokeAction()).  I would also expand the definition to encompass all
      types of "updates" for clarity.

      New edit:

      It should be possible for a Consumer to batch create, read, update
      and delete multiple properties of the Producer with one invocation.
      It should also be possible to perform this operation in conjunction
      with other operations.

Question:  What other operations might be perform in batch they we would
want to include in the reqs, if any?
