Summary

Fixes #100: a register whose transforms validate their outputs against its own blocks (outputs.profiles) published those blocks' shaclShapes as working-directory-relative paths. Every register that imported them then failed. In ogcapi-sosa's case the published register.json had entries like this:

ogc.sosa.properties.observation → _sources/properties/observation/shapes.shacl

A downstream register then failed with:

Error processing _sources/csdm/features/CSD/_sources/properties/observation/shapes.shacl: [Errno 2] No such file or directory

That's because a relative entry is resolved against the importing bblock's own directory.

Cause: RdfValidator.__init__ writes the bblock's resolved inherited shapes back into bblock.metadata['shaclShapes'], as paths relative to the working directory, for postprocess to turn into URLs. validate_transform_output() also builds an RdfValidator for the output profile. That profile has usually been processed already, with its published shaclShapes made absolute, so the write-back replaced them with relative paths after the fact.

Change:

• RdfValidator takes publish_shacl_shapes: bool = True.
• validate_transform_output() passes False.
• Validation itself is unchanged: the shapes are still loaded for the validator's own graphs.

Testing

• New tests in tests/test_validate.py. They check that validate_transform_output() builds RdfValidator with publish_shacl_shapes=False, and that RdfValidator leaves shaclShapes untouched when it's False and writes them when it's True. The new tests fail without the fix.
• Full suite inside the bblocks-postprocess:latest image venv, with pytest and pytest-mock installed: 181 passed.
• End to end: I built a copy of an ogcapi-sosa fork with spec-example transforms that validate against the sosa property blocks, with this branch's ogc/ mounted over the image's /src/ogc.
  • 47/47 blocks pass, and no shaclShapes entry is relative.
  • Before the fix, the same build published relative paths for observation, execution, actuation, sampling and observationCollection.
  • Transform-output profile validation still ran: 212 passed and 2 failed, the same counts and the same two files as the unpatched build.
