Graph.validate() fails when Brick ontology is preloaded to the graph

[emesar]

For a simple graph that only includes the Brick ontology, validation appears to fail.

from brickschema import Graph

g = Graph(load_brick=True)
_, _, report = g.validate()
print(report)

The resulting report:

Validation Report

This is due to recent changes in QUDT, which caught some insufficient extensions of QUDT we were doing in Brick. As long as you just have these QUDT results in your validation result, you should be ok. We are working on fixing these validation issues in the main Brick repo

[Maghnie]

Is there a recommended workaround?

Currently, I'm using this hard-coded if condition

...

valid, _, results_text = g.validate()

qudt_errors = True if results_text.count("Result Path: brick:hasQUDTReference") == 38 else False

if valid or qudt_errors:
    print("Graph is valid")
else:    
    print("Graph is not valid")
    print(results_text)

...

[gtfierro]

Hi @Maghnie the reason this is failing is because you do not have the QUDT ontology loaded in. You can use https://github.com/gtfierro/ontoenv-rs?tab=readme-ov-file#python-library to load the dependency ontologies into the same graph before you validate, and that should address the issues.

I will also make a note to update the tutorial and address these issues for future users! Please let me know if this addresses your issue and if you ahve any other questions

[Maghnie]

Thanks for the quick reply!

Can the pyontoenv package work on Windows?

When I try to run the example from the pyontoenv readme, I get this error

Creating new OntoEnv
Traceback (most recent call last):
File "[...]\pyontoenv_example.py", line 7, in
env = OntoEnv(cfg)
^^^^^^^^^^^^
ValueError: IO error for operation on brick: Das System kann die angegebene Datei nicht finden. (os error 2)

And sure enough, my virtual environment doesn't have any source files for pyontoenv, even though I tried to install the package with pip install pyontoenv. I also tried pip install ontoenv, since there was a pip entry for that, but it didn't work either.

[gtfierro]

Yes, it should work on Windows. If you update to pyontoenv==0.1.10a2, then you should be able to change the line of the xample to cfg = Config(strict=False, offline=True). The current code is failing because you don't have a "brick" directory locally.

[Maghnie]

Still won't work - I'm not sure if I'm missing something 😅.

I updated the pyontoenv version and the Config arguments as you mentioned above. Also copied the "brick" directory from the ontoenv-rs repo locally. For good measure, I deleted the automatically created .ontoenv directory from previous runs. Now I get a different error:

Config path: Some(".\\.ontoenv\\ontoenv.json")

@Maghnie just wanted to ping you to let you know that I'm working on a better example of how to do this, and I'm fixing a few bugs along the way. Thanks for your patience!
