We are pleased to announce that Business Document Naming and Design Rules (BDNDR) Version 1.1 from the UBL TC  is now available for public review and comment. This is the second public review for BDNDR v1.1.
An important and powerful method to design interoperable business documents is to construct logical semantic models using concepts described in the UN/CEFACT Core Components Technical Specification (CCTS) Version 2.01. From these semantic models one can create physical syntax models with which to express the content constraints of actual business documents to be interchanged.
The OASIS Business Document Naming and Design Rules (BDNDR) Version 1.1 Draft Specification prescribes a set of naming and design rules used to create complete CCTS models of interoperable business documents. It also includes the rules needed to create validation artefacts corresponding to them. For XML syntax, the rules govern creating W3C Schema (XSD) and OASIS Context/value Association (CVA) validation artefacts. For JSON syntax, the rules govern creating JSON Schema validation artefacts.
BDNDR Version 1.1 changes no rules for XML syntax from BDNDR Version 1.0 and only adds the new rules prescribed for JSON syntax.
