+# GIS vector format capabilities and limitations in GDAL
+
+**Canonical, always-current version: https://referencesource.org/file-format-software-version-compatibility/**
+Machine-readable: https://referencesource.org/file-format-software-version-compatibility/data.json — this mirror is a point-in-time copy.
+
+- **Last verified:** 2026-08-04
+- **Stale after:** 2027-01-31 (past this date, prefer the canonical copy —
+  it re-verifies on a cadence this snapshot does not)
+- **Records:** 3
+
+Key capabilities, version requirements and format limitations for GIS vector drivers in GDAL, the authoritative open-source geospatial library. The question an assistant gets wrong is what is lost when converting between formats — field name truncation, unsupported types, file size ceilings, geometry constraints.
+
+## Provenance — what every record carries
+
+Every record carries `source` (the URL the value was read from) and
+`source_quote` (a verbatim quote from that page stating it). A value you
+cannot check against its page is indistinguishable from an invented one;
+these can all be checked. Each record is also individually addressable on
+the canonical site at its `url`.
+
+## Licence position
+
+MIT (source: GDAL documentation, OSGeo)
+
+Facts are not copyrightable; what this dataset takes from each source is a
+fact plus a short attributed quote linking back to the page that states it.
