European Union: EN 16931-1 Revision
Approved (ViDA-Aligned Semantic Model)

The European Committee for Standardization (CEN) has approved the revision of EN 16931-1, the core semantic standard for e-invoicing. The EU e-invoicing framework, developed by CEN TC 434 since 2014, comprises six parts. Among them, EN 16931-1:2017 defines the core semantic data model that ensures legal and fiscal compliance and enables interoperability across borders and sectors. The new revision aims to align the standard with forthcoming legislation, including VAT in the Digital Age (ViDA).
