A vocabulary is always identified by its short name and sometimes it may offer multiple sub-vocabularies with different names. Both are listed below.

Click the + icon (if present) to expand the tree. If the full ontology or the term heirarchy is not loaded into this site, then the tree will consist of all terms at the same level. For some vocabularies, only a subset of terms are loaded
