UBL Northern European Subset

The Northern European Subset (NES) defines the specific use of UBL 2.0 electronic procurement documents domestically and between the member countries: Denmark, Sweden, Norway, Finland, Iceland, and the UK. NES documentation includes profiles describing business processes and scenarios, profiled UBL documents, and guidelines on the specific usage of UBL entities, as well as schema and schematron validation tools.

OIOUBL Implementation Guidelines

OIOUBL is a UBL customization for specific Danish business requirements developed in coordination with other Nordic countries and the UK under a collaboration called the "Northern European Subset" (NES). The 15 business documents included in OIOUBL constitute a subset of UBL 2.0 covering the supply chain business processes from sourcing to billing. The support package referenced here comprises a series of guidelines for implementors of OIOUBL. These include comprehensive explanations of business rules as well as examples of the use of the associated business documents. In addition, a series of guidelines describe the use of certain classes common to different types of business documents. This package can be used as a template for producing other implementation guidelines.
