CCTS 3.0 Implementation Verification Second Iteration

UN/CEFACT has recently published an updated implementation verification version of its Core Components Technical Specification (CCTS) V3 specification. CCTS is an important specification to SAP and its customers and partners.  SAP uses CCTS in conjunction with other UN/CEFACT standards to define its Global Data Types which are at the heart of its  business objects and service definitions.


UN/CEFACT originally released the implementation verification version in February 2008.  Under the UN/CEFACT Open Development Process (ODP), implementation verification is the final phase of its standardization process. In this phase, the specification is considered sufficiently mature to the point that actual implementations of the proposed standard are used to validate its usability and technical accuracy. Implementation feedback is accepted from any potential user and all feedback is reviewed and considered by the team prior to finalization of the specification.


This new implementation verification version incorporates comments received from early implementers. The principal change from the first implementation verification version is a refinement of the expression of data type value domains.  This refinement incorporates new concepts related to the use of context methodology and breaks new ground for using code lists and identifier schemes to define value domains as alternatives to simple primitive types such as decimal, integer, binary object, string and the like.  Data types will now be allowed to have different value domains defined at both design and run time using context values to identify the specific value domain to be used in a given situation.


Interested parties are encouraged to download the CCTS Version 3.0 Implementation Verification Second Iteration and consider using for their own implementation verifications. It is anticipated that given the maturity of the specification, minimal changes would be required to such implementations once the standard is published.
