Fwd: [ebcore] Groups - CPPA 3, 2015 edition, draft version 0.1 uploaded

Dear all,

      

      The last unfinished part of the OASIS ebXML specifications is the
      CPPA specification.    The last version that made it to OASIS
      Standard is still the version 2.0 of 2002, which became part of
      ISO 15000 in 2004.  The ebXML CPPA TC continued work for several
      years and even produced a substantial draft version 3.0 some years
      ago,  which was submitted to the ebCore TC when the CPPA TC
      closed.   That draft had many improvements, innovations and
      enhancements. One part of this draft was later extracted into a
      standalone document, the ebCore Party ID Type specification, which
      was standardized and became an OASIS Committee Specification in
      2010, and is widely used with ebMS2 since 2007 and now also with
      ebMS3 in Asia, Australia among other places, and in Europe.  

      

      Unfortunately, apart from ebCore Party ID Type,  the CPPA v3
      specification was unfinished as there were few individuals working
      on it,  and those individuals were also working on other
      specifications such as ebMS3 and AS4.  The work on those other
      specifications took a lot of resources and for most of us had a
      higher priority, as one main goal of CPPA3 was to enable
      configuration of ebMS3 and AS4-based B2B communication, so
      successful adoption of ebMS3 and AS4 was part of the business case
      for CPPA3.   Today, AS4 is taking off, with (to my personal
      knowledge) at least 18 software companies providing, or planning
      to provide, AS4 implementations, not counting several open source
      initiatives. There are major end user communities adopting AS4
      internationally, and millions of productions ebMS3 messages have
      been exchanged to date.  There still is no standardized,
      product-independent configuration for AS4, it is  time we provide
      one and IMHO the CPPA work is the best starting point. 
      Furthermore, CPPA can help configure other protocols, including
      legacy protocols.

      

      The ZIP file uploaded to the ebCore repository (see below)
      contains an updated CPPA3 schema with embedded documentation. 
      Using a commercial tool,  I generated documentation in a very
      user-friendly HTML format in the "documentation"  directory.   
      This tooling makes it very easy to develop an XSD and its
      documentation in parallel.  One other TC has adopted this
      approach, which is approved by OASIS TC-Admin (I checked with
      them), as long as we also provide, at some later stage, a
      (minimal) OASIS specification with the usual front and back
      matter, bibliography etc.   

      

      The draft CPPA3 uploaded below currently supports the following
      functionality:

      -   Configuration of ebMS2 as in CPPA2.  

      -   Several enhancements and improvements for ebMS2, 
      incorporating lessons learned in a decade of use of ebMS2 and
      CPPA2.

      -   Simplification and flattening of structures.  CPPA2 could
      handle exotic complex structures but the common easy structures
      could be quite complex.

      -   Support reuse of structures.  Abstract concepts such as ebMS3
      PModes are very redundant as they don't take into account reuse of
      values.

      -   Configuration of most of ebMS3 Core and setting almost all
      PMode Parameters defined in the Core Specifications (see
      documentation). The few exceptions are some parameters only needed
      for Web Services Reliable Messaging and Web Services Reliability,
      use of which has not taken off and which are not used  in AS4.
      CPPA3 has extensibility mechanisms so someone can extend it to
      support these specifications but for now they are not covered in
      the draft as the business case does not seem to be there.

      -   Full configuration of AS4.

      -   Full configuration of EDIINT: AS1,  AS2 and AS3.   This was a
      requirement for communities that use e.g. AS2 today and want to
      add support for AS4. CPPA3 provides this.

      -   Configuration of basic Web Services, including WS-Security,
      with extensibility options.

      -   Extensibility framework,  allowing new protocols,  new package
      etc. to be added later in an easy way.

      -   Support for a simplified,  template-based "named protocol" (or
      named profile) option.  This is common practice in many ebXML
      applications,  but also elsewhere. The documentation shows how
      this can be supported.

      -   Support for automated CPA formation from CPPs.  In v2, there
      were practical complications or underspecified situations. For
      v3,  we want to avoid this and only finalize the spec and schema
      when we have defined and implemented a fully automated formation
      process.   In parall to defining and documenting the schema,  I am
      working on a new implementation of automated CPA3 formation from
      CPP3 documents, to be open source.  This implementation can be
      published via OASIS (ongoing discussions on supporting software
      deliverables) or otherwise.  

      

      To do (incomplete list):

      -   Complete the embedded documentation and derived HTML
      representation.

      -   Functionality for ebMS3 Part 2.

      -   Functionality for ebMS3 SAML Profile.

      -   Complete CPA formation implementation.

      -   Provide non-schema specifications.

      -   Review by TC and generally.

      

      The next steps can be discussed in upcoming ebMS and/or ebCore
      meeting.

      

      Kind Regards,

      

      Pim
