Converter for unidirectional EN16931 invoices from CII D16B to UBL 2.1, 2.2, 2.3 or 2.4.

This is a Java 11+ library that converts a Cross Industry Invoice (CII) into a Universal Business Language (UBL) document following the rules of the European Norm (EN) 16931 that defines a common semantic data model for electronic invoices in Europe.

Special care was given to XRechnung invoices - all the CII examples of them translate to UBL that is valid according to the EN 16931 validation rules.

Seehttps://peppol.helger.com/public/locale-en_US/menuitem-tools-rest-api#cii2ubl for a service implementation using this library.

This library is licensed under the Apache License Version 2.0.

The binary releases are available on Maven Central athttps://repo1.maven.org/maven2/com/helger/en16931-cii2ubl/ and below.

This is a pure Java library and not a self-contained conversion tool.You can convert CII D16B invoices following the EN 16931 rules to different UBL versions.The entrance classes are:

• Create UBL 2.1:com.helger.en16931.cii2ubl.CIIToUBL21Converter
• Create UBL 2.2:com.helger.en16931.cii2ubl.CIIToUBL22Converter
• Create UBL 2.3:com.helger.en16931.cii2ubl.CIIToUBL23Converter (since v1.3.0)
• Create UBL 2.4:com.helger.en16931.cii2ubl.CIIToUBL24Converter (since v2.1.0)

The main conversion method is calledconvertCIItoUBL and takes either aFile as input or a pre-parsedun.unece.uncefact.data.standard.crossindustryinvoice._100.CrossIndustryInvoiceType object (that reading is done with classcom.helger.cii.d16b.CIID16BCrossIndustryInvoiceTypeMarshaller fromph-cii).Additionally anErrorList object must be provided as a container for all the errors that occur.

The conversion is deemed successful, if a non-null object is returnedand if the error list contains no error (errorList.containsNoError ()).

Replacex.y.z with the effective version you want to use:

<dependency>  <groupId>com.helger</groupId>  <artifactId>en16931-cii2ubl</artifactId>  <version>x.y.z</version></dependency>

Call it viajava -jar en16931-cii2ubl-cli-full.jar followed by the options and parameters.
