In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this section.
Geometry
The geometry of OGR VRT features may be identified by the wkb_type attribute. The valid values for this attribute are:
| wkb_type | Description |
|---|---|
| wkb_none | FME Feature with no geometry |
| wkb_point | 2D Point feature |
| wkb_point_xyz | 2.5D Point feature |
| wkb_line | 2D Linear feature |
| wkb_line_xyz | 2.5D Linear feature |
| wkb_polygon | 2D simple polygon or donut feature |
| wkb_polygon_xyz | 2.5D simple polygon or donut feature |
| wkb_geometry_collection | 2D Feature with multiple geometries |
| wkb_geometry_collection_xyz | 2.5D Feature with multiple heterogeneous geometries |
| wkb_multi_point | 2D Feature with multiple point geometries |
| wkb_multi_point_xyz | 2.5D Feature with multiple point geometries |
| wkb_multi_line | 2D Feature with multiple line geometries |
| wkb_multi_line_xyz | 2.5D Feature with multiple line geometries |
| wkb_multi_polygon | 2D Feature with multiple polygon geometries |
| wkb_multi_polygon_xyz | 2.5D Feature with multiple polygon geometries |
| wkb_geometry | All geometries allowed |
| wkb_unknown | All geometries allowed |
VRT Attribute Type Mapping

| string(1) | fme_char |
| real(width, decimal) | fme_decimal(width, decimal) |
| datetime | fme_datetime |
| date | fme_date |
| time | fme_time |
| integer | fme_int32 |
| real(10,0) | fme_uint32 |
