Online OIOUBL Dokumentation

Danish implementation of UBL customization for support of the basic procurement process. You can find all documentation in English and Danish. OIOUBL has been developed in coordination with the "North European Subset" (NES), as an initiative where the involved countries work together on content and use of the electronic business documents based on the UBL 2.0 standard.

The site immediately presents online hyperlinked documentation for the structure and purpose of all the elements in CommonLibrary and each of the 15 (used) UBL business documents.

Northern European Subset

NES is a cooperation among several European countries: Denmark, Norway, Sweden, UK, Finland and Iceland. The initiative comprises representation from both government and industry.

The site provides a set of specifications, that shows how the participating countries plan to apply UBL.

NES Version 2 contains a set profiles, guidelines, code lists (most useful for European countries) and validation tools.

ebXML and UBL

The ebXML suite of specifications, many of them now standardized as ISO 15000, provides a complete XML-based infrastructure that enables EDI functionality over the free Internet. UBL provides a standard data format for the messages to be exchanged in such an infrastructure; however, UBL is designed to be agnostic with respect to the infrastructure, and UBL messages can be used in a very wide range of functional contexts, from complex service-oriented architectures (SOAs) to the simple exchange of documents via email.
