Refactoring the ebMS schema

["Pim van der Eijk" <pvde@sonnenglanz.net>]

Hello,

Following up on the last bullet from my message below:

The ebint:RoutingInput schema attempts to reuse as much as
possible the ebMS 3.0 Core schema for elements in
UserMessage. Unfortunately, there is only an eb3:Messaging
element that can be reused when importing the ebMS 3.0 Core
schema into other schemas.  All other elements are local to
that element's type, and the same is true for its
subelements and their types. As a result, the ebint schema
in
http://www.oasis-open.org/apps/org/workgroup/ebxml-msg/docum
ent.php?document_id=33933 has to define not only a new
ebint:UserMessage, but also ebint:MessageInfo,
ebint:PartyInfo, ebint:CollaborationInfo and
ebint:PayloadInfo.  Is this acceptable or undesirable?

If the latter, here is an approach:  it is possible to
refactor the ebMS 3.0 Core schema to have reusable element
definitions for MessageInfo, PartyInfo, CollaborationInfo
and PayloadInfo. See attached:
"ebms-header-3_0-200704_refactored.xsd"
This allows the ebint schema to reuse the elements from this
schema. See attached:
"ebms-multihop-1_0-200902_refactored.xsd"
An example that is valid against this ebint schema is
attached:  "example_ebint.xml"
The difference to the examples posted in
http://lists.oasis-open.org/archives/ebxml-msg/201001/msg000
22.html is that there the subelements are from the ebint
schema.

The ebint:UserMessage has an optional MessageInfo, so that
element (and its type) should stay in the ebint schema as
the ebMS 3.0 Core UserMessage has a required MessageInfo.

The refactored ebMS 3.0 Core schema validates the exact same
messages as the ebMS 3.0 Core Spec.  The attached regular
ebMS 3.0 core "example.xml" is valid with both the 3.0 Core
XSD and the refactored schema.  Since the exact same
instances are valid or invalid in both schemas, I think the
refactored XSD for the Core schema could qualify as an
erratum only. 

What do people think?

Pim

Hello,

The lists of things to do to finish part 2 includes at
least:
-  Some discussion on Pulling.  In Core spec, you could pull
submitted user messages (or get an EmptyMPCError).  In Part
2, you can Pull anything that has an ebint:RoutingInput to
it.  And some of those things were not "submitted" (to an
MSH by an application) but received (from another MSH) for
forwarding.  
-  Review all options for Pull requests (from edge
intermediary, end-to-end pulling, something in-between):
when do they need a reference parameter, when do they need a
nextmsh @role, verify that we can configure all options
using the current Pmodes.
-  The ebint:RoutingInput schema could reuse more from the
Core Spec if we had global elements other than just
eb3:Messaging. Is that an option?
-  Add some text on ConversationId in RoutingInput (Not set
via Pmode, do we leave this to implementations or recommend
some approaches ?)
-  General editorial work (language, references, formatting,
style etc.).
-  Thorough review ..

Other than this we are almost there ..

Pim
