+### Development Context / Details:
+The ontology is one manifestation of the underlying SEPIO Information Model.  This information model is being developed as part of the GA4GH Variant Annotation (VA) workstream, to support data exchange across GA4GH systems, and has drifted from what is in the current SEPIO ontology found here.  The ontology will be updated to reflect these changes in the near future (likely fall 2023).  A link to documentation for the GA4GH VA Information Model that will the the basis for these updates will be provided here wiht the first release of this model (Summer/Fall 2023).
