Subject: [ubl-comment] UBL Schemas released for public review


The first draft of a royalty-free data representation standard for
electronic commerce has been released by the OASIS Universal
Business Language (UBL) Technical Committee.

The UBL Library Content 0p70 Public Review release can be found at


A zip file containing the entire review set packaged for local
installation can be downloaded from


Intended to become international standards for electronic trade,
the UBL schemas contained in the review package specify
machine-readable XML representations of familiar business
documents.  The seven basic documents covered in this release
include Order, Order Response, Simple Order Response, Order
Cancellation, Despatch Advice, Receipt Advice, and Invoice.
Together, they can be used to implement a generic buy/sell
relationship or supply chain whose components fit existing trade
agreements and are immediately understandable by workers in
business, supply-chain management (SCM), Electronic Data
Interchange (EDI), accounting, customs, taxation, and shipping.

These generic schemas are intended to work in a wide variety of
business contexts through custom extensions.  Automated context
configuration will be addressed in a later phase of the effort.
The schemas are also designed be used in their generic form in
many ordinary business contexts without further modification.

The business context in which the generic document types are
designed to function is detailed in the materials accompanying the
release.  Other documentation includes the entire semantic model
on which the schemas are based, a description of the methodology
by which the schemas were created, and UML diagrams to aid in
software design.  The package also contains alternative ASN.1
specifications for the UBL schemas that allow ASN.1 tools to be
used for UBL document transfers.  Additional supplementary
materials will be made available in a following package update to
be announced separately.

The UBL schemas reflect a number of inputs, the most important of
which are the commercial xCBL schemas from Commerce One and SAP;
the ebXML Core Components Specification; early XSL stylesheet
implementations; and early feedback from the UBL Liaisons
(http://oasis-open.org/committees/ubl/lsc/).  UBL schema design
follows the UBL Naming and Design Rules developed by the UBL NDR
Subcommittee (http://oasis-open.org/committees/ubl/ndrsc/).  The
definition of UBL semantic content, based on existing practice in
EDI and electronic marketplaces, has taken place in close
alignment with ebXML Core Components methodology to ensure optimal
integration into the ebXML semantic registry.

As works in progress, the materials in the Library Content 0p70
Public Review package do not yet have the status of an OASIS
Standard or an OASIS Committee Specification.  The construction of
experimental prototypes based on these materials is encouraged for
the purpose of generating input back to the committee process, but
implementers are strongly advised against basing commercial or
mission-critical applications on the draft specifications.
