Getting ontology as LinkML schema?

[serenalotreck]

I'm trying to use OntoGPT for information extraction, which is a tool that requires a schema input in LinkML format. I'd love to use PO, but I've been unable to figure out how to convert from OWL to LinkML. It seems straightforward to do in the other direction, but no amount of googling has helped me figure out how to go from OWL --> LinkML. My understanding of different ontology specification formats is limited, but I suspect it may be because OWL encodes data beyond just the schema -- however, I'm not sure why that would preclude the schema from being pulled out of an OWL ontology and put into LinkML format.

Wondering if your team has any insights for how to go about doing this?
