[OpenLayers-Users] GeoRSSClient - a generic JavaScript class for GeoRSS layers

[Nick Whitelegg]

In an effort to try and factor out common code for developing GeoRSS-based 
marker layers, useful for instance for OpenStreetMap mashups,  I have started 
to develop a class called GeoRSSClient which allows you to (hopefully) easily 
add capabilities to view, add and delete GeoRSS-based marker layers to an 
OpenLayers-based application.

It's available from the OpenStreetMap SVN archive 
(http://svn.openstreetmap.org) under utils/georss. A quick summary of how it 
works - it has three modes: normal - for viewing georss layers, add - for 
adding new markers (which will be added to the server too), and delete - for 
deleting markers (which will be deleted from the server too). 

For adding or deleting markers from the GeoRSS server, it's set up at the 
moment to talk to a server which will accept the following parameters: (this 
probably needs making more REST-compliant...)

action : add or delete
description: the description of the feature (goes in the RSS description tag)
type: the type of the feature (goes in featuretypetag)
lat
lon
link : the link associated with the tag (if any)
title: the title of the feature (goes in the RSS title tag)
guid: (delete only) the ID of the feature to delete

I can think of a number of ways to improve this but if anyone has any comments  
please let me know.
