I recently tried to make a feed acting as a linking page. I am impressed by the "src" attribute of atom:content. Then I made a feed entry as follow.
<entry> <title>Example Title</title> <id>http://www.example.org/</id> <content type="text/html" src="http://www.example.org/"; /> <published>2006-11-19T13:05:00Z</published> <updated>2006-11-19T13:05:00Z</updated> </entry> Unfortunately, numbers of feed aggregators will not follow the src attribute probably due to security reasons. While I want to provide alternate text, I cannot find a way to do so since the specification of Atom mentioned, 'If the "src" attribute is present, atom:content MUST be empty.' As a result, I use atom:summary. <entry> <title>Example Title</title> <id>http://www.example.org/</id> <link rel="" <summary type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml";> <p>Please proceed to <a href="http://www.example.org/";>http://www.example.org/</a> for contents.</p> </div> </summary> <content type="text/html" src="http://www.example.org/"; /> <published>2006-11-19T13:05:00Z</published> <updated>2006-11-19T13:05:00Z</updated> </entry> However, it is actually an abuse of atom:summary because the "atom:summary" element is a Text construct that conveys a short summary, abstract, or excerpt of an entry. More unfortunately, feed aggregators will not consider this entry is linking to http://www.example.org/ even though the content is external. As a result, atom:link is added. <entry> <title>Example Title</title> <id>http://www.example.org/</id> <link rel="alternate" type="text/html" href="http://www.example.org/"; /> <summary type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml";> <p>Please proceed to <a href="http://www.example.org/";>http://www.example.org/</a> for contents.</p> </div> </summary> <content type="text/html" src="http://www.example.org/"; /> <published>2006-11-19T13:05:00Z</published> <updated>2006-11-19T13:05:00Z</updated> </entry> I did not imagine how complicated the situation is. And after doing so many things, <content type="text/html" src="http://www.example.org/"; /> is proved to be useless. However, I do hope that it is useful. The followings are my thoughts. 1. When the "src" attribute of atom:content is present, it includes the meaning of having an alternate link to the same URI inside "src". 2. atom:content SHOULD NOT be empty. I think that atom:content is something like xhtml:object. Alternate contents should be put inside the element. For examples: <content type="text/html" src="http://www.example.org/";> <content type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml";> <p>Please proceed to <a href="http://www.example.org/";>http://www.example.org/</a> for contents.</p> </div> </content> </content> Or <content type="text/html" src="http://www.example.org/"; alternatetype="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml";> <p>Please proceed to <a href="http://www.example.org/";>http://www.example.org/</a> for contents.</p> </div> </content> I do think providing alternate content is important.
