Schema is here: http://downloads.bbc.co.uk/podcasts/ppg.xsd
Some background: we use this format to move data around internally within the podcast publishing application. We examined other available formats - OPML/TV-A/etc, but none seem to fit our requirements. You can see that this is designed as a program guide sort of thing and includes a lot of BBC-specific information. You could use it to build an iTunes-style feed browser for BBC content. Is it a useful data set? Is it just XML soup? As Carlos said, feedback is appreciated. -- Phil Miller Technical Lead, Media Services BBC News Interactive [EMAIL PROTECTED] +44 7799 894180 > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf > Of Carlos Roman > Sent: 04 December 2007 14:56 > To: [email protected] > Subject: [backstage-developer] BBC Podcasts (sorry no OGG) > > > Figured rather than using the other list this might be the > best place to ask/show a Podcast feed.
