This FAIRsharing record describes: The Sickle Cell Disease Ontology (SCDO) project is a collaboration between H3ABioNet (Pan African Bioinformatics Network) and SPAN (Sickle Cell Disease Pan African Network). The SCDO is currently under development and its purpose is to: 1) establish community standardized SCD terms and descriptions, 2) establish canonical and hierarchical representation of knowledge on SCD, 3) links to other ontologies and bodies of work such as DO, PhenX MeSH, ICD, NCI’s thesaurus, SNOMED and OMIM. The source of this description is the metadata record on FAIRsharing.org, an educational and informative resource that describes and links databases, standards, and data policies. FAIRsharing also creates collections of these resources and recommendations of databases and standards based on 3rd party data policies.
