Table of Content

Normative

To define the reference model as the organising framework for CEFACT standards. Updating the ebTA from 1999 and in accordance with the open-EDI reference model.
To define the relationships between all CEFACT technical and business standards - positioning them within the reference model.
To define dependencies on external standards (eg that the XML NDR depends on W3C XMl Schema)

Informative

To define CEFACT "release packages" as a set of compatible specific versions of technical and business standards.
To identify gaps in CEFACT standards that, if filled, will add value to the CEFACT product (eg WS* profile for UMM).
To publish this information as a navigable model to the TMG website and to maintain it on a regular basis.

To integrate CEFACT standards into a common reference model in order to ensure consistency and completeness.

Number	Name	Description	Comment	Contributor
1	Conceptual Reference Model	Update the 1999 ebTA to reflect current developments within CEFACT. the reference model to provide a framework for classifying and positioning CEFACT standards and the external standards upon which CEFACT specifications depend (eg XML Schema, UML, 11197, etc)	Initial requirement for the EBAS project.	Gunther Stuhec
2	Dependencies & packagng	To populate the reference model with the actual collection of specific CEFACT specifications - defining dependencies between them and on external standards. Collecting consistent sets of specifications together into "release packages".	Requirement stated by Ian Watt, MRI chair and Australia HoD. Steve Capell listed as contributor until Ian registers on this site.	Steve Capell
3	Integrated Meta-Model	A more detailed and granular expression of requirement #2. To collect together formalised MOF expressions of the formal meta-model behind all CEFACT technical specifications. To integrate these meta-models into a consistent and extensible framework. Publish the integrated meta-models as MOF, UML, and XML Schema (based on XMI).	Requirement stated by Mikkel Brun and Peter Borresen representing Danish government & UBL. Steve Capell listed as contributor until Mikkel / Peter register on this site. The XML schema version (generated from MOF according to XMI 2.1) is effectively a schema for interchange of models (eg process models, core component libraries, etc).	Steve Capell
