Electronic invoicing - Part 5: Guidelines on the use of sector or country extensions in conjunction with EN 16931-1, methodology to be applied in the real environment
This document describes how trading partners may extend the Core Invoice Model and the related business rules and code lists, to support business cases that are specific to their trading environment, while at the same time maintaining semantic interoperability with the Core Invoice Model.
This document does not define a methodology for creation of a Core Invoice Usage Specification, nor does it describe the detailed process of syntax binding.
Elektronische Rechnungsstellung - Teil 5: Leitfaden über die Verwendung von branchen- oder länderspezifischen Erweiterungen der EN 16931-1 einschließlich einer im realen Umfeld einzusetzenden Methodik
In diesem Dokument wird beschrieben, wie Handelspartner das Kernrechnungsmodell und die dazugehörigen Geschäftsregeln und Codelisten erweitern dürfen, um Geschäftsszenarien, die für ihre Handelsumgebung spezifisch sind, gerecht zu werden und gleichzeitig die semantische Interoperabilität in Bezug auf das Kernrechnungsmodell aufrechtzuerhalten.
Dieses Dokument enthält weder eine Definition der Methodik zur Erstellung einer Anwendungsspezifikation einer Kernrechnung noch eine detaillierte Beschreibung des Prozesses der Syntaxeinbindung.

European foreword
This document (FprCEN/TS 16931-5:2024) has been prepared by Technical Committee CEN/TC 434
“Electronic invoicing”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Vote on TS.
This document will supersede CEN/TR 16931-5:2017
This document includes the following significant technical changes with respect to
CEN/TR 16931-5:2017:
— Updating concepts in alignment with EN 16931-1.
— Introducing the concept of Extension Components. This should greatly improve interoperability
cross-sector and intra-EU where Extended Information Elements are required.
— Changing the definition of the Terms Compliant and Conformant. Previously they were based on
TOGAF terminology[10]. This avoids confusing the terms when used in legal text compared to
normative text.
— Compliant now refers only to legal specifications
— Conformant refers only to normative text
— Recommending the use of multilateral business agreements rather than bilateral when using
Extension Specifications.
