Doh! Due to permission problems on the hosted server, the online demo wasn't saving properly. Should be working now. http://www.phildawes.net/2004/03/veudas (e.g. do a label search for 'veudas' or 'phil') Cheers, Phil Phil Dawes writes: > > Hi RDF Interest, > > I'm like to announce the latest beta of veudas - my experimental web > rdf browsing and editing tool. > > This release is basically a complete rewrite of the tool.
