Is anyone aware of a good existing ontology for roadmaps?

The [Lifecycle Schema](https://vocab.org/lifecycle/) might be worth looking into. I became aware of it because of it’s usage in [solid-focus](https://github.com/NoelDeMartin/solid-focus) by @NoelDeMartin.

Maybe the [PAIR Ontology](https://www.virtual-assembly.org/pair-ontology-general-view/) is also interesting.
