The purpose of this deliverable is to specify and describe the reference architecture applied as the basis for the development of Business Interoperability Interface specifications in the eProcurement domain by the CEN/TC 440 Technical Committee.

This document describes:
-   the rationale for building customisation supporting business cases that are specific to their business environment while maintaining organisational and semantic interoperability with the TC 440 specifications;
-   the difference between Usage specification and Extension specification;
-   a methodology on how to define customisations on:
-   BII Transaction specification,
-   Business rules,
-   Code lists;
-   how to claim compliance or conformance to a customisation of a TC 440 specification;
-   the connection to the eProcurement Ontology project.
This specification does not describe the detailed process of building an extension.
