+ * Notes about the implementation:

+ * - The item author is not supported as it needs to be an e-mail address to be
+ *   valid.
+ * - The RSS specification does not explicitly allow to have more than one
+ *   enclosure as every item is meant to provide one "story", thus having
+ *   multiple enclosures per item may lead to unexpected behavior.
+ *   On top of that, it requires to have a length specified, which RSS-Bridge
+ *   can't provide.
+ * - The Media RSS extension comes in handy, since it allows to have multiple
+ *   enclosures, even though they recommend to have only one enclosure because
+ *   of the one-story-per-item reason. It only requires to specify the URL,
+ *   everything else is optional.
+ * - Since the Media RSS extension has its own namespace, the output is a valid
+ *   RSS 2.0 feed that works with feed readers that don't support the extension.

+
+&lt;p&gt;So we developed JSON Feed, a format similar to &lt;a href="http://cyber.harvard.edu/rss/rss.html"&gt;RSS&lt;/a&gt; and &lt;a href="https://tools.ietf.org/html/rfc4287"&gt;Atom&lt;/a&gt; but in JSON. It reflects the lessons learned from our years of work reading and publishing feeds.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href="https://jsonfeed.org/version/1"&gt;See the spec&lt;/a&gt;. It’s at version 1, which may be the only version ever needed. If future versions are needed, version 1 feeds will still be valid feeds.&lt;/p&gt;
+
+&lt;h4&gt;Notes&lt;/h4&gt;
+
+&lt;p&gt;We have a &lt;a href="https://github.com/manton/jsonfeed-wp"&gt;WordPress plugin&lt;/a&gt; and, coming soon, a JSON Feed Parser for Swift. As more code is written, by us and others, we’ll update the &lt;a href="https://jsonfeed.org/code"&gt;code&lt;/a&gt; page.&lt;/p&gt;
+
+&lt;p&gt;See &lt;a href="https://jsonfeed.org/mappingrssandatom"&gt;Mapping RSS and Atom to JSON Feed&lt;/a&gt; for more on the similarities between the formats.&lt;/p&gt;
+
+&lt;p&gt;This website — the Markdown files and supporting resources — &lt;a href="https://github.com/brentsimmons/JSONFeed"&gt;is up on GitHub&lt;/a&gt;, and you’re welcome to comment there.&lt;/p&gt;
+
+&lt;p&gt;This website is also a blog, and you can subscribe to the &lt;a href="https://jsonfeed.org/xml/rss.xml"&gt;RSS feed&lt;/a&gt; or the &lt;a href="https://jsonfeed.org/feed.json"&gt;JSON feed&lt;/a&gt; (if your reader supports it).&lt;/p&gt;
+
+&lt;p&gt;We worked with a number of people on this over the course of several months. We list them, and thank them, at the bottom of the &lt;a href="https://jsonfeed.org/version/1"&gt;spec&lt;/a&gt;. But — most importantly — &lt;a href="http://furbo.org/"&gt;Craig Hockenberry&lt;/a&gt; spent a little time making it look pretty. :)&lt;/p&gt;</content>
