Allow the user to tick a checkbox to save the currently displayed style in QGIS for the layer, write it as a new SLD file, then upload it and apply it to the uploaded layer.

See: http://www.webrian.ch/2012/04/native-sld-support-in-qgis.html

Same as #5 but with a raster.

Refactor geonode-extract to get back all the files (style, metadata, data) from a geonode, given the typename.

For example:

def download(geonode_url, name):
...

download('http://localhost:8000', 'geonode:rivers')

Include dependencies with plugin (gsconfig, requests and other new one if necessary) before releasing the plugin

Write it in the same format that geonode-extract uses to download from geonode, this will be then used to upload into geonode.

Create basic table UI to list the layers available on the GeoServer instance, allow the user to select the layers he wants and then to download the selected one. Optionally, add the layer to the current QGIS workspace.

The user should be asked if he/she wants to override or not the data if there is already the same datastore (for shapefiles) in GeoServer.

I am not sure if it is possible yet with the QGIS api, see http://www.webrian.ch/2012/04/native-sld-support-in-qgis.html (it is a year old so it may be possible now)

Have at least title, description and keywords out of qgis and into an ISO xml (like the one provided by geonode), verify this information is correctly uploaded to geonode.

Refactor geonode-extract to let you get the list of layers with metadata as a python object.

List the layers from the current QGIS workspace. Allow the user to select some layers and to upload them to GeoServer.

Export the basic metadata from GeoServer into an ISO xml

Allow the user to choose the workspace he wants to upload the feature to. By default, load the data into the defined default workspace

Upload a sld file if there is one with the same name as the shapefile in the same folder and apply it as the default style

Operations using gsconfig.py requires login and password even for public layers.
One option could be to enable a workflow using only ows to access public layers.

For each QGSLayer object created in https://github.com/GFDRR/geoserver_bridge/blob/master/storage/qgscatalog.py#L24

Each of these lines using gsconfig.py library:
https://github.com/GFDRR/geoserver_bridge/blob/master/storage/qgslayer.py#L29-L34
is making between 5 and 15 calls to the server.

For instance:

self.workspace = self.resource.workspace.name does the following calls:

/geoserver/rest/layers/ds_divisions_admin_level_4.xml
/geoserver/rest/workspaces.xml
/geoserver/rest/workspaces/geonode/datastores.xml
/geoserver/rest/workspaces/geonode/datastores.xml
/geoserver/rest/workspaces/geonode/coveragestores.xml
/geoserver/rest/workspaces/geonode/coveragestores.xml
/geoserver/rest/workspaces/geonode/datastores/postgres_imports/featuretypes.xml
/geoserver/rest/workspaces/geonode/datastores/postgres_imports/featuretypes.xml

Need to cut down the number of calls and do some local caching.
Also, need to use some UI tricks, displaying initially only the workspace name and display the layers only when unfolding a workspace name

Something like that to show a pop up dialog:

import errno
try:
    ...
except socket.error, v:
    errorcode=v[0]
    if errorcode==errno.ECONNREFUSED:
        Show dialog "Connection Refused"

By default, when clicking on a row, only one cell is selected and not the entire row which then causes issues for processing. Instead select the entire row when any cell in the row is clicked.

Using the code developed in #4, load a vector layer directly to geonode.

Create a function to load a layer as downloaded from Geonode, into the active QGIS workspace.

Look into the code at: http://github.com/AIFDR/inasafe and http://github.com/safe/safe-geonode for some examples of code handling download from geonode and loading layers into qgis.

When exporting to a file, enable the user to choose the export location

Start with some basic text boxes.
Also allow the users to specify the folder where the data is downloaded to.
