List canon provenance rows
Canon module
GET/canon/provenancescanonProvenances.list
A provenance rank. A lower rank never overwrites a populated higher-rank field. Returns a cursor page of canon provenance rows the caller may see. The default order is `provenance` ascending. Supports sparse fieldsets and the filter grammar.
- Requires the capability canon.taxonomy.read.
- OAuth scopes: canon.
- Cursor-paginated: limit, cursor, fields, sort and filter apply.
- Error statuses: 400, 401, 429. Errors are RFC 9457 problem details.
Path and query parameters
| Field | Type | Required | Description |
|---|---|---|---|
| limit | Limit | No | Page size. Default 50, maximum 200.Constraints: range 1 to 200 |
| cursor | Cursor | No | Opaque cursor from `next_cursor` of the previous page.Constraints: length 1 to any |
| fields | Fields | No | Sparse fieldset: a comma-separated list of top-level fields to return. `id` is always returned.Constraints: pattern ^[a-z_][a-z0-9_]*(,[a-z_][a-z0-9_]*)*$ |
| sort | Sort | No | Sort keys, comma-separated; a leading `-` sorts descending. Without `sort`, the documented default order applies (coded lists sort in numeric code order).Constraints: pattern ^-?[a-z_][a-z0-9_]*(,-?[a-z_][a-z0-9_]*)*$ |
| filter | Filter | No | Filter grammar `filter[field][op]=value`. Operators: eq, ne, lt, lte, gt, gte, in (comma-separated values), is_null (true or false) and contains. Conditions combine with AND. |
Response 200: a page of CanonProvenance
| Field | Type | Required | Description |
|---|---|---|---|
| provenance | Provenance | Yes | Provenance from `xpms.dim_provenance` (Section 3.8); a lower rank never overwrites a higher one.Constraints: pattern ^[a-z]+$ |
| rank | integer | Yes | Rank, higher wins.Constraints: range 0 to any |
| definition | string | Yes | Definition, in sentence case.Constraints: length 1 to 20000 |
| may_overwrite | string | Yes | What this provenance may overwrite.Constraints: length 1 to 300 |
| max_confidence | AssertionLabel | Yes | Assertion label from `xpms.dim_assertion_rank` (Section 3.8).Constraints: pattern ^[A-Z]+$ |
