oni
Oni is a web service that provides a RESTful API for managing a tree structure of names used by annotation tools and data catalogs. We typically call this tree structure a "knowledgebase" (aka "KB"). Tree structures are useful for modeling organism phylogeny. At MBARI, we also include other terms, such as geological features and equipment used for research.
It is a replacement for https://github.com/mbari-org/vars-kb-server and https://github.com/mbari-org/vars-user-server.
Oni includes APIs for fast search and retrieval of terms, fetching branches of the knowledgebase, and user accounts. Individual nodes in the KB are called concepts, and each concept may have one primary name (e.g. the accepted taxa name) and zero or more alternative names (such as synonyms, common names, former taxa names, etc.)
