How to load multiple files into one ontology?

[KonradHoeffner]

I am trying to import the RDFBones ontology, which consists of 6 owl files that belong to the same ontology (graph). All 6 files are included under the 'products' key in config/ols-config.yaml. However it seems as if OLS only loads RDFBones-main and none of the others. How can I get OLS to load all 6 files?

There is no way to do this in OLS. You can use a tool like ROBOT to merge the files into a single file to load in OLS.
