Problem: AIP pointer file validation is failing

[tw4l]

Expected behaviour

AIP pointer files pass validation.

Current behaviour

All AIP pointer files are failing validation. The Storage Service debug logs are full of messages like:

/var/log/archivematica/storage-service/storage_service_debug.log:153406:ERROR     2020-08-27 10:45:51  locations.models.package:package:create_pointer_file:1450:  Pointer file constructed for 9e6c5762-ba8b-4bd1-86b3-8cc8758aa497 is not valid.

Looking more closely at the logs, we see:

xmllint output gets us a little closer to the problem:

pointer.e1d88fc7-18d8-4e9d-a59e-e758f114d6c0.xml fails to validate

This does not result in the ingest failing, as the results aren't passed to MCP Server. The AIP is stored successfully and the pointer file is created and appears otherwise fine.

Steps to reproduce

• Ingest a compressed AIP
• Look through Storage Service debug logs for error messages

Your environment (version of Archivematica, operating system, other relevant details)

qa/1.x / qa/0.x pre-1.12 release

Additional details

This isn't entirely new - I see the same error message in #380, where it was noted as something needing investigation but was tangential to the main problem described there.

I investigated this today and realized it's caused by the mets-reader-writer's schematron files (for METS and pointer file validation) still using PREMIS 2.2 when the Storage Service uses PREMIS 3.0.
