OPML 2.0 Will Support Includes

OPML is a simple outline format which has been most commonly used to manage RSS feed lists. The problem I've run into is that it's a static document, so the feed list needs to be manually updated. I subscribe to a lot of feeds, many of them on group blog sites. It would be great to be able to subscribe to an OMPL link and automatically get any newly added feeds in my aggregator.

The OPML 2.0 (draft) spec is out for review, and it has support for includes. The new include type allows you to link to an OPML list by a URL and you'll always be in sync. When this spec is finalized and implemented in aggregators, this will cut my feedlist in half. Cool!

Here's an example of an OPML that includes the entire weblogs.asp.net feed list (assuming I'm reading the spec correctly):

<?xml version="1.0" encoding="ISO-8859-1"?>
<opml 
version="2.0">
    <
head>
    <
/head>
    <
body>
        <include 
text="weblogs.asp.net" url="http://weblogs.asp.net/Opml.aspx" />
    <
/body>
<
/opml>
