BICAN Knowledge Graph Models
LinkML data models for the BRAIN Initiative Cell Atlas Network (BICAN) knowledgebase: taxonomies, assertions and evidence, library generation, anatomical structures, genome annotation, donors and a BICAN subset of Biolink. JSON Schema and Pydantic models are generated from the LinkML sources.
