Kosso's podcast.com seems to get away with plain old OPML... http://my.podcast.com/kosso/opml/
He's a friend of this list[1] so may be happy to help. Other options are the emerging RDF programme ontology (ask Michael Smethurst whether he's willing to announce the URL yet, I'm not going to spoil his fun!), or even Media RSS itself might be able to do it Or perhaps we could make one of these formats work with a custom extension element or two? As you all know, when it comes to XML schemas, wheel reinventing is highly frowned upon... Brendan. [1] Well maybe he's sort of the list's strange uncle who tells odd stories at Christmas, but we love him anyway :-) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Philip Miller Sent: 04 December 2007 16:11 To: [email protected] Subject: RE: [backstage-developer] BBC Podcasts (sorry no OGG) 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.
