AASConstraintViolation when trying to read the DEXPI template in basyx-python-sdk

[JS-Aibel]

I am not able to read the template IDTA 02012-1-0_Template_DEXPI.aasx with the basyx-python-sdk aasx.AASXReader.

When reading the file, multiple AASConstraintViolations of type Constraint AASd-123 and Constraint AASd-127 occurs.
I have tested with the Handover Documentation template, and the aasx.AASXReader works fine.

The following changes made the Submodel template readable:

• Removing the Submodel Elements of type “ReferenceElement” and “RelationshipElement”. This solved the constraint violations.
• Remove the value of the File elements ModelFile and ModelRepresentation. The files are not attached in the AASX file.

It seems the error is with these elements.

Hi @Rudra-sandeep,
Any status on updating the DEXPI template to a working example?

To solve the constraint violation for the ReferenceElement in the MappingDirectory, you can follow these steps. Note that I have not investigated the other issues with the template.

• ValueError: Key(type=FRAGMENT_REFERENCE, value=ProteusXML@ID=ProcessInstrumentationFunction-3) is not preceeded by a key of type File or Blob, but Key(type=SUBMODEL_ELEMENT, value=ModelFile) (Constraint AASd-127)
• ValueError: The type of the first key of an ExternalReference must be a GenericGloballyIdentifiable: Key(type=SUBMODEL, value=https://epc.org/sm_id/9f236679-e52d-4a52-aa85-dea871a89f9b) (Constraint AASd-122)
