I'd recommend working your way through this tutorial: http://docs.djangoproject.com/en/1.2/intro/ to learn about using it. The tutorial should take less than an hour if you are familiar with Python already, and it will also help you to learn about adding and customizing pages in Django/GeoNode. There is already a 'category' field on Layers which you may be able to adapt to your needs. I know the folks at Harvard Worldmap have done so already so they may be able to provide some pointers (or you can peruse their code on github.) > We want to customize search.

Currently data search is delegated out to the CSW service in GeoNode so you will either need to reimplement the search code in Python/Django or customize GeoNetwork to use edit distance for search. > > -- > Regards > Smitha V > MT2009149 > IIITB > > -- David Winslow OpenGeo - http://opengeo.org/
