xCBL 4.0 Final Release Notes
About xCBL 4.0
xCBL 4.0 is the first release of xCBL using W3C XML Schema (XSDL) as the canonical form. This will be the standard for future releases of xCBL. Previously, all xCBL releases were based on SOX schema. xCBL 4.0 also represents an initial alignment with the OASIS Universal Business Language (UBL) initiative. Some of the UBL recommendations have been adopted in the design of xCBL 4.0. As UBL continues to evolve and mature, additional recommendations and standards will be adopted by xCBL.
With a few exceptions, business documents that existed in xCBL 3.5 have been carried over to xCBL 4.0. New documents have also been added to xCBL 4.0 to support integration of applications with backend ERP systems.
xCBL 4.0 Features
Multiple namespaces - A major difference between xCBL 4.0 and previous xCBL versions, aside from being XSDL based, is the use of multiple namespaces. The use of multiple namespaces follows a UBL recommendation and provides greater flexibility for versioning of business documents defined within xCBL. The structure of the namespaces allows for independent versioning of namespaces. In previous versions of xCBL, if a single change was made to the schema, all of xCBL had to be released as a new version. The use of multiple namespaces also has other benefits, such as for performance.
Retains the semantics of xCBL 3.5 - xCBL 4.0 is derived from xCBL 3.5. In general, there is no is no data lost going from xCBL 3.5 to xCBL 4.0 but there are some cases where elements from xCBL 3.5 have been dropped.
Transformation Maps - Transformation maps between xCBL 3.5 and xCBL 4.0 are created using a third party tool. Some of the transformations have been completed but work continues towards a final set and we are exploring the best way to make these available. Please use the yahoo-xcbl discussion group if you have questions about the transformations (http://groups.yahoo.com/group/xcbl-discuss/).
General changes from xCBL 3.5 to xCBL 4.0:
xCBL 4.0 Namespaces
For xCBL 4.0, an "RRN" (Resolvable Resource Name) uri scheme has been adopted for namespace declaration. This is similar to what was recently done to the xCBL 3.5 single document XSDL versions. We are in the process of formally submitting the uri scheme to relevant bodies.
