	/**

	 * <p>Save the existing changes for this resource (for example, save the layer

	 * to disk or to the database, etc). The resource should not be closed at this

	 * point (files, database connections, etc should no be closed), as they may

	 * be still needed by other extensions. Resources should be closed at

	 * {@link IExtension#terminate()}.</p>

	 * 

	 * @return true if the data was correctly saved, false if it was not saved

	 * (there are many reasons for this: there was an error, the user cancelled

	 * the process, etc).
