Create Empty Dataset Endpoint

Parent catalog record UUID

Internal PostGIS table name

Current EPSG SRID of stored geometry

OGC geometry type, e.g. MultiPolygon

True when the underlying column is generic GEOMETRY (created sketch datasets): the dataset accepts ANY geometry subtype on write regardless of the display geometry_type above. Computed on the detail endpoint only; list endpoints always report false.

True if geometry has Z dimension

Number of coordinate dimensions (2, 3, or 4)

Minimum Z value across all features

Maximum Z value across all features

Credit line the source's terms require to be displayed wherever the data is rendered. Shown verbatim in the map viewer's attribution control.

Original file format, e.g. GPKG, SHP

EPSG SRID of the uploaded source file

Monotonic version counter

URL the data was originally fetched from

How the data entered the catalog: upload, postgis, service, stac, or created. Computed from source_format and record_type, not stored; null for collections and VRTs, which have no origin of their own.

Machine-readable pointer back to the origin, written only by ingest and refresh. Distinct from source_url, which is editable descriptive metadata. Null for uploads and created datasets. It is also null for any reader who is neither the dataset's owner nor an admin — origin (above) and the freshness/health fields below are not gated and still describe the dataset's capabilities.

Last committed successful refresh — not the last attempt

Last time GeoLens contacted the origin at all, whether the attempt succeeded or failed

healthy, missing, inaccessible, or unknown. 'unknown' means never probed, or an origin kind with nothing to probe.

Why the origin is not healthy, as one of a fixed set of GeoLens codes: auth_required, blocked_by_policy, item_withdrawn, network_error, not_found, server_error, timeout, unauthorized, unexpected_status. Null when healthy or never probed. Never provider text, a URL, or a response body — nothing the origin sent is stored here.

none, drifted, or unknown. Set at refresh commit from the schema diff; 'unknown' until a refresh has run.

fresh, due, overdue, or unknown, computed from last_refreshed_at against the declared update_frequency: due past one declared period, overdue past two. 'unknown' when the origin cannot be refreshed at all (created), when no cadence is declared (asNeeded, irregular, notPlanned, unknown), or when nothing has been refreshed yet. Advisory only; never blocks an operation. Distinct from the quality score's own freshness, which measures quality_detail.computed_at rather than the source.

Access level: private, restricted, internal, public

Lifecycle status. Deliberately not pinned to an enum: the values come from the workflow extension's status_order(), so an overlay may define its own. Community default order: draft, ready, internal, published.
