Atom feed for video player does not validate, namespace issue?

[tucotuco]

Greetings,

I'm new to xml, perhaps you can help with what I *think* is a namespace issue. Attempted to validate code at W3 XML Validator and with XML Copy Editor, but not much help is offered on how to fix the problem. I'm hoping to use this Atom feed to load videos into the JW MediaPlayer (

http://www.longtailvideo.com).

Would really appreciate some help on where I've gone wrong. Thanks!

Here's the code:

<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="

http://www.w3.org/2005/Atom"

xml:lang="en">
<title>Joe's Videos</title>
<link rel="alternate" type="text/html" href="

http://atompub.org"/>

<link rel="self" type="application/atom+xml" href="

http://www.alta-publishing.com/demo/joe/joe-atom.xml"/>

[1] I suppose it is a yahoo media rss extension, hence the namespace uri ([ignore]

http://search.yahoo.com/mrss/

[/ignore]). If not, it is suffice to change it to the correct uri and respect the schema of it.

[2] Furthermore, certain attribute would then not conforming with the namespace (prefixed by media), specifically, it is the type attribute of media:thumbnail. Hence, I eliminate it for you to add back.

[3] There are some mandatory elements missing, such as id, updated, link which must appear in the entry elements. You have to add them.

[4] You have also to add the author to the channel element.

With all the above considerations, this is an revised feed for you to re-do. You have to discover the revisions.
