Children
- Coding - A structured representation of a coded/enumerated data value, that includes additional metadata about the code and code system.
- Entity - Anything that exists, has existed, or will exist.
- Expression - A structure for labels representing systematic expressions that describe an entity, as generated by formal nomenclatures (e.g. HGVS for genetic variants, ISCN for karyotypes, HLA nomenclature for HLA genes/alleles).
- Extension - A data structure that allows implementations to define and create custom fields within an Entity to capture information not supported by the core specification.
- RecordMetadata - A re-usable structure that encapsulates provenance metadata that applies to a specific concrete record/encoding of information, as opposed to provenance of the abstract information content/knowledge the record represents.
