ph-bdve

A generic document validation engine originally developed for PEPPOL but now also supporting other document types.

This project is divided into sub-projects each keeping tracking of one document type set:

  • ph-bdve - generic "Business Document Validation Engine"
  • ph-bdve-peppol - the PEPPOL specific setup etc
  • ph-bdve-simplerinvoicing - Dutch SimplerInvoicing 1.x support from https://github.com/SimplerInvoicing/validation
  • ph-bdve-en16931 - Validation rules for the EN 16931 (European e-Invoicing norm based on CEN TC 434)
  • ph-bdve-ehf - Validation rules for EHF (Norwegian public procurement) - since 4.0.1
  • ph-bdve-ubl - Validation rules for pure UBL (without any Schematron) - since 4.0.1
  • ph-bdve-cii - Validation rules for pure CII (without any Schematron) - since 4.0.1
  • ph-bdve-energieefactuur - Validation rules for Dutch Energie eFactuur - since 4.0.2
  • ph-bdve-oioubl - Validation rules for Danish OIOUBL - since 4.0.3
  • ph-bdve-ebinterface - Validation rules for Austrian ebInterface - since 5.0.0
  • ph-bdve-teapps - Validation rules for Tieto TEAPPSXML - since 5.0.0
  • ph-bdve-ublbe - Validation rules for e-FFF/UBL.BE - since 5.0.5

A running example can be found on PEPPOL Practical.

A standalone tool that just performs validation based on this library is the phoss validator.

Usage guide

Basically this library wraps different XML Schemas and Schematrons and offers the possibility to validate XML documents based on the rules.

Validation executor set identification

Every set of validation artefacts is uniquely identified based on a structure that is similar to Maven coordinates. The identifier for a set of validation artefacts is a so called "VESID" ("Validation Executor Set ID"). Each VESID consists of a mandatory group ID, a mandatory artefact ID, a mandatory version number (ideally following the semantic versioning principles) and an optional classifier. E.g. the "PEPPOL Invoice Fall release 2018" is identified with the group ID eu.peppol.bis2, the artefact ID is t10 (based on "transaction 10" from CEN BII - historical reasons...), the version number is 3.7.0 (representing "Fall 2018") and no classifier is present. Another example is "SimplerInvoicing 1.2 invoice" which has the group ID org.simplerinvoicing, the artifact ID invoice and the version number 1.2 (also without a classifier).

Each VESID can be represented in a single string in the form groupID:artifiactID:version[:classifier]. Neither group ID, nor artifact ID, nor version number, nor classifier may contain the colon (':') character, any bracket character ('<' and '>') nor any other character forbidden in filenames in any OS.

How to validate documents

At least the ph-bdve project and one of the domain specific projects (like e.g. ph-bdve-peppol) is needed in your application. See the section on usage in a Maven project below. All available VES must be registered in an instance of class ValidationExecutorSetRegistry (which can simply created via new). Depending on the used domain specific libraries, initialization calls for registration into the registry must be performed. Example for registering (only) PEPPOL validation artefacts:

    final ValidationExecutorSetRegistry aVESRegistry = new ValidationExecutorSetRegistry ();
    PeppolValidation.initStandard (aVESRegistry);
    PeppolValidation.initThirdParty (aVESRegistry);
    return aVESRegistry;

The instance of class ValidationExecutorSetRegistry can be kept as a singleton - it is thread-safe. Therefore the registration process need to be performed only once.

Validating a business document requires a few more steps.

  1. Access to the registry is needed.
  2. A specific VESID instance (e.g. PeppolValidation370.VID_OPENPEPPOL_T10_V2) - there are constants available for all VES identifiers defined in this project.
  3. The ValidationExecutionManager is an in-between class that can be used to customize the execution (e.g. setting a class loader). But it is created very quickly, so there is no harm on creating it on the fly every time.
  4. An instance of class ValidationSource to identify the document to be validate. Class ValidationSource has factory methods for the default cases (having an org.w3c.dom.Node or having an com.helger.commons.io.resource.IReadableResource).
  5. The validation results are stored in an instance of class ValidationResultList. This class is a list of ValidationResult instances - each ValidationResult represents the result of a single level of validation.
  6. Your application logic than needs to define what to do with the results.
    final IValidationExecutorSet aVES = VESRegistry.getOfID (aVESID);
    if (aVES != null) {
      final ValidationExecutionManager aVEM = aVES.createExecutionManager ();
      // What to validate?
      ValidationSource aValidationSource = ...;
      final ValidationResultList aValidationResult = aVEM.executeValidation (aValidationSource);
      if (aValidationResult.containsAtLeastOneError ()) {
        // errors found ...
      } else {
        // no errors (but maybe warnings) found
      }                                                                       
    }

Potential issues

Please ensure that your stack size is at least 1MB (for Saxon). Using the Oracle runtime, this can be achieved by passing -Xss1m on the command line. This only seems to be a problem when running 32bit Java. With 64bit Java, the default stack size of the Oracle JVM is already 1MB.
