The UN/CEFACT Techniques and Methodologies Group is pleased to announce that the UN/CEFACT Core Component Technical Specification (CCTS) V3.0 project has completed the public review period under the UN/CEFACT Open Development Process (ODP) and has now transitioned to Implementation Verification. The Implementation Draft may be downloaded from
CCTS V3.0 Draft Specification for Implementation Verification

Under the ODP, all interested parties are encouraged to verify the validity of CCTS V3.0 through actual implementation. This verification review period is the most critical part of the development process, as it permits potential problems and issues to be identified. Taking the results of the review into consideration, the editing group further refines and improves the specification. This step is completed when at least two independent bodies have successfully implemented the specification.

If you are interested in participating in the implementation verification, or have comments on the Implementation Draft, please contact our secretary Jim Wilson

Abstract of CCTS V3.0

The purpose of the project is to produce the next version of the Core Components Technical Specification (CCTS), taking into account comments received during the implementation verification period of Version 1.95, comments submitted by UN/CEFACT TBG17 and comments submitted by implementers and users of CCTS Version 2.01.

Use of CCTS V3.0

The specification can be employed wherever business information is being defined for interoperability among and between enterprises, governmental agencies, and/or other organizations in an open and worldwide environment. It defines a meta model and rules necessary for describing the structure and contents of conceptual and logical data models and information exchange models.
