There are several ontologies already well built out. Utilities and pharma both have them as an example. They are built by committee of vendors and users. They take a bit to penetrate the approach and language used. Often they are built to be adaptable.
I’ve had good success with CIM for Utilities to build a network graph for modelling the distribution and transmission networks adding sensor and event data for monitoring and analysis about 15 years ago.
Anywhere there is a technology focussed consortium of vendors and users building standards you will likely find a prebuilt graph. When RDF was “hot” many of the these groups spun out some attempt to model their domain.
In summary, if you need one look for one. Maybe there’s one waiting for you and you get to do less convincing and more doing.
