    4747WFS 1.1.0 spec has also defined some new operations, like GetGMLObject, LockFeature… We are not going to support these commands yet in this updates. In this enhancement, we will focus on the elements and operations which already existed in 1.0.0 version but changed in 1.1.0 version.

    5151WFS1.1.0 uses GML 3 instead of GML 2 as default format for DescribeFeatureType and GetFeature request. Currently FDO can only handle GML 2 correctly and have some problem with GML 3, we need to enhance it to support both versions well. This includes two aspects:
    5252
    53 GML 3 to FDO[[BR]]
     53  GML 3 to FDO[[BR]]
    5454
    55   •     GML 3 schema to FDO schema
     55    •   GML 3 schema to FDO schema
    5656
    57   •     GML 3 feature to FDO feature (FDO only has a reader API, used by the WFS provider, which exposes GML features as FDO features. This API should be updated to handle GML 3)
     57    •   GML 3 feature to FDO feature (FDO only has a reader API, used by the WFS provider, which exposes GML features as FDO features. This API should be updated to handle GML 3)
    5858
    59 FDO to GML 3[[BR]]
     59  FDO to GML 3[[BR]]
    6060
    61   •     FDO schema to GML 3 schema
     61    •   FDO schema to GML 3 schema
    6262
    63   •     FDO feature to GML 3 feature
     63    •   FDO feature to GML 3 feature
    6464
    6565Note: Those transform functions are implemented in the FDO component.

    67 3.      Handle different version request
     673. Handle different version request

    6969Currently, the WFS FDO provider uses version 1.0.0 (hard-coded) while sending the request to server. So first, we need to accept version information while open connection, and also set the correct version in the request parameters. Similar with WMS FDO provider, the design solution is to store the version information in the Feature server connecting property. And parse it in the provider, a default version will be provided if user doesn’t set.
