Hi, Do you mean that the output from GeoServer WFS 2.0 is not valid because it does not seem to have gml:id for the collection, nor for the geometries, but it does have gml:id for the members?

In that case the GML 3.2 schemas require each geometry to have a gml:id. So this is a geometry id, not a feature id ( in case of geometry collections, you'll have one id for the collection and as many ids as members) To address that technical requirement, MapServer generates it in a sequential way for the output of each request. Not completely sure it matches the uniqueness intended but at least it validates schemas. So this particular one is not a good candidate to be exported to other formats, but I see Thomas has just replied for the feature id. >> >> However, with GeoJSON as outputformat the id is missing: >> { >> "type": "FeatureCollection", >> "crs": { "type": "name", "properties": { "name": >> "urn:ogc:def:crs:OGC:1.3:CRS84" } }, "features": [ { "type": >> "Feature", "properties": { "PK_UID": 1, "STATE_NAME": "Illinois", >> >> >> GeoJSON specification says in >> http://geojson.org/geojson-spec.html#feature-objects: "If a feature >> has a commonly used identifier, that identifier should be included as >> a member of the feature object with the name "id"." >> >> GeoJSON from Geoserver WFS does contain the id: > >> {"type":"FeatureCollection","totalFeatures":49,"features":[{"type":"Fe >> ature ","id":"states.1","geometry":{"type":"MultiPolygon" >> >> Should this be classified as a bug or a candidate for a featere request? >> >> -Jukka Rahkonen- -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
