Slot: field_annotation¶
REDCap's field annotation column — free text plus action tags (e.g. @HIDDEN, @READONLY, @CALCTEXT). Any structured convention layered inside it (semantic variable codes, ontology-coded choices, ontology versions, interoperability mappings) is defined downstream by rarelink, not by this base schema.
