mw wiki ext wikibase item statement update ID STATEMENT_ID [PROPERTY] [flags]
Read the entity revision before editing one statement. Use update ID STATEMENT_ID –rank preferred for a rank-only edit preserving all other native fields. Scalar edits preserve existing qualifiers/references and rank; –input supplies a complete native statement replacement. Statement IDs are opaque and checked against this entity. Supported typed datatypes are listed under –datatype; –raw-json with –input skips datatype-specific validation for other native types. Property/datatype compatibility is finally checked by the wiki. Dry-run reads state but fetches no CSRF token and writes nothing. Failed writes are never retried automatically.
