What ontologies are important because these are used a lot? Some of the ones I came across:
Since 2016 there was some progress: https://github.com/schemaorg/schemaorg/issues/280 https://github.com/schemaorg/schemaorg/issues/1186
The last time I looked into it was for music: https://www.wikidata.org/?oldid=297764900#schema.org/MusicRecording
Mapping properties is tedious but a relatively amount of work (tens of hours rather than hundreds) can make a significant difference.
