[OASIS Issue Tracker] Created: (ODATA-594) Discrepancy between ATOM and JSON formats (GML, GeoJson) for Polygon information content

Discrepancy between ATOM and JSON formats (GML, GeoJson) for Polygon information content
----------------------------------------------------------------------------------------

                 Key: ODATA-594
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-594
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData JSON Format
    Affects Versions: V4.0_OS
            Reporter: Evan Ireland
             Fix For: V4.0_ERRATA01


GML seems to require that Polygons specify (usually) an exterior ring, but also permits the specification or zero or more interior rings.

GeoJSON only seems to allow a single set of points (see example in http://geojson.org/geojson-spec.html#id4)

For OData, one would hope that there is some kind of notion of the information content of Polygon coordinates which is independent of the format (ATOM or JSON) that we use. (Even if this information content is not formally documented, we could imagine that it exists).

Unfortunately, this mismatch in Polygon coordinates between GML and GeoJSON seems hard to fit into a single information model.
