Provide improved ontology level metadata

To make a good FAIR impression, we should improve our metadata:

dcterms:description, e.g. "An application ontology for clinical data at Critical Path Institute. (ADDMORE" dcterms:license, e.g. https://creativecommons.org/licenses/by/4.0/ dcterms:title "Critical Path Ontology" dcterms:contributor : a list of all ORCIDs that have one way or another contributed to CPONT

@dolson Do you want to try to figure out appropriate values for these fields?
