If you want to download the UMLS content, which makes up most of the ontologies that are *not* available for download, you'll have to transform the original content into ontologies yourself using the UMLS2RDF software (https://github.com/ncbo/umls2rdf), using a UMLS key obtained from National Libraries of Medicine (see https://www.nlm.nih.gov/research/umls/). We can not promise this will always work, as sometimes updating the script for the latest UMLS changes may be required.
