Overview

The proposal ask for creation of a dedicated sandbox in order to work on new GUI components in order to easily build new GUI based on GeoNetwork server module.

Objectives:

• Create components to compose Search, Admin, Editor interface
• Provide a default GeoNetwork UI
• Provide developers documentation on components
• Clean existing client code based (removing JS dependencies)
• Improve existing server services in order to provide simple access to each module (eg. User management, System admin)

These components are written in JS and depends on:

• OpenLayers
• Ext.js
• (optional) GeoExt

A separate GUI application is created and minor changes should occur on the server side (service improvements or new services for simple tasks like "get groups").

Example of a GeoExt MapPanel linked to search results :
