Human Reference Atlas Common Coordinate Framework Ontology

given comment: The Common Coordinate Framework (CCF) Ontology is an application ontology built to support the development of the Human Reference Atlas (HRA). It unifies vocabulary for HRA construction and usage—making it possible to ingest external data sources; supporting uniform tissue sample registration that includes the spatial positioning and semantic annotations within 3D reference organs; and supporting user-formulated cross-domain queries over tissue donor properties, anatomical structures, cell types, biomarkers, and 3D space.
