Hi @jonassmedegaard - thanks for the feedback.

I think this is because .instances defaults to False instead of a list.

The method .instances was a quick way to pull out class instances from the class - rather than extracting all of them in advance, which is what is required in order to build documentation pages programmatically.

The recent version 1.9.9.2 provides a more solid way to handle instances i.e. they can be all be extracted and indexed when Ontospy is instantiated (hide_individuals=False) by providing a flag.

I'll reset .instances to return an empty list by default. That should fix it
