=== Voting History ===
 * Vote proposed by X on Y, result was +/-n (m non-voting members).

----

== Motivations ==
The current configuration is based on:
 * 4 input fields to define bounding box coordinates with a list of regions to quickly set up those 4 values.
 * Bounding polygon could be define using GML object definition within the editor. But then user need to type coordinate of gmd:polygon elements manually.


The propsed change is to display a map in edit/view mode in order to be able to draw/display the metadata extent.


== Proposal == 

The map is in default WGS84 projection.
In view mode:
 * the map navigation is disabled
 * the map zoom to the feature
 * one map is displayed for each extent bounding polygon or bounding box.
In editing mode:
 * a draw rectangle tool is activated for bounding box
 * a draw polygon tool is activated for bounding polygon
 * the list of region is available to quickly define a bounding box
 * a clear button allows to clear the feature.
 * navigation and mouse coordinate controls are available.

The config-gui.xml allows to define global parameters:
 * map size
 * list of projection (used to display bounding box coordinate in different projection.

...

=== Known improvements ===
 * Change map projection.
 * Select feature from WFS (on going)
