OIOUBL is a customization for Danish business requirements of the international UBL 2.0 standard from OASIS (the Organization for the Advancement of Structured Information Standards). The primary advantage of OIOUBL is the standardization of business documents for different uses. And because UBL 2.0 is a flexible, international standard that supports many business requirements, documents can be exchanged across national borders. Another advantage of OIOUBL is the possibility of developing fully automated procurement processes in which the electronic documents are validated and matched automatically. This creates financial savings though the cost of human resources normally required for clerical process. (Quelle: http://www.epractice.eu/en/cases/oioubl)
