Where to get validation files

Here are some examples of files you can download to set up your validation.

Peppol BIS (UBL)

If you want to validate Peppol BIS UBL documents, you’ll need 3 separate validation files:

1. Whether the document is a valid UBL document, through the relevant ‘maindoc’ files from OASIS: UBL xsd (note: you’ll need every file in common/ and the relevant files for your document type, such as Invoice-2 or Order-2, from maindoc/)
2. Whether the document is a valid EN-16931 document, through the schematron file provided by OpenPeppol
3. Whether the document is a valid Peppol BIS document, through the schematron file also provided by OpenPeppol

NLCIUS

If you want to validate SI-UBL 2.0 (NLCIUS) documents, you’ll need 2 validation files:

1. Whether the document is a valid UBL document, through the relevant ‘maindoc’ files from OASIS: UBL xsd (note: you’ll need every file in common/ and the relevant files for your document type, such as Invoice-2 or Order-2, from maindoc/). This is the same as for Peppol BIS (or any UBL 2.1 document).
2. The SI-UBL xsl validation file, which can be found on the NPA’s github
