-ikiwiki's simple podcasting, while elegant and minimal, doesn't (as
-mentioned in [[todo/blogging]]) produce full-featured feeds. In
-fancy podcasts, episodes are accompanied by text content. The feeds
-also have lots more metadata.
-
-[[!toc]]
-
-## Design
-
-7. For each fancy podcast episode, write a blog post containing
-   `\[[!meta enclosure="WikiLink/to/media.mp3"]]`. (Don't specify
-   more than one enclosure -- but if you do, last one wins.)
-7. When rendering to HTML (single-page or inlined), append a link
-   to the media file.
-7. When rendering to RSS/Atom, the text is the entry's content and
-   the media file is its enclosure.
-7. Don't break simple podcasts in pursuit of fancy podcasts.

-## Implementation

 [[!template id=gitbranch branch=schmonz/fancypodcast author="[[schmonz]]"]]
 [[!tag patch]]
 
-### Completed
+Nothing new since 2013/07/21 [[merge|done]] to `master`.
 
-* Cover the existing simple podcast behavior with tests.
-* Add an `enclosure` field to [[plugins/meta]] that expands the
-  given [[ikiwiki/WikiLink]] to an absolute URL (feed enclosures
-  pretty much need to be, and the reference feeds I've looked at
-  all do this).
-* Write failing tests for the desired single-page and inlined
-  HTML behavior, then make them pass by adding enclosure stanzas
-  to `{,inline}page.tmpl`.
-* Write failing tests for the desired RSS/Atom behavior, then make
-  them pass via changes to `{atom,rss}item.tmpl` and [[plugins/inline]].
-* Match feature-for-feature with
-  [tru_podcast](http://www.rainskit.com/blog/542/tru_podcast-a-podcasting-plugin-for-textpattern)
-  (what [[schmonz]] will be migrating from).
-* Enrich [feed metadata](http://cyber.law.harvard.edu/rss/rss.html)
-  by catching up `rsspage.tmpl` to `atompage.tmpl`.
-* Subscribe to a fancy feed in some common podcatchers and verify
-  display details against a reference podcast.
-* Verify that the feeds validate.

-* Think carefully about...
-    * UTF-8.
-    * Other templates with `CONTENT` and whether they want to learn
-      about `ENCLOSURE` (maybe `aggregatepost.tmpl`?).
-    * Whether [[tips/howto avoid flooding aggregators]] suffices for
-      migrating a fancy podcast into ikiwiki.
-* Verify that _all_ the tests pass (not just my new ones).
+## Future improvements
 
------
+### Embedded audio/video player in browsers
 
-## Future improvements
+* For a given enclosure, depending on autodetected MIME:
+    * `audio/*` -> `<audio>`
+    * `video/*` -> `<video>`
+* For a given template:
+    * `page.tmpl` -> eagerly fetch media
+    * `inlinepage.tmpl` -> fetch just enough to display durations
+* Only for HTML5 sites, or also okay for XHTML?
+* Does this work well enough in enough browsers, or do we need a
+  JavaScript player to fill in some gaps?
 
 ### iTunes fancy podcasting

-    * Else, add `itunes` as a third kind of feed (RSS plus more stuff).

+      some feed readers?
+    * Is it even valid to include them in Atom feeds? If so, do
+      Atom podcasts look any better in podcatchers?
+    * Avoid adding a third kind of feed (`itunesrss`), or options
+      to the existing `rss` and `atom` feeds, unless we have to.
 * Notable tags for feeds:

     * `itunes:author`

-### Other ideas
+### Fancy podcast aggregating
 
-* Let the enclosure's MIME type be specified, in case someone ever
-  needs to disagree with `File::MimeInfo`.
-* Extend [[plugins/inline]] to configurably generate additional
-  subscription links (such as iTunes) alongside the RSS/Atom ones.
-* Verify that [[plugins/more]] plays well with fancy podcasts.
-* Allow enclosures that are outside the wiki.
-* Support Apple's "enhanced podcasts" (if they're still relevant).
+* Write tests comparing a fancy podcast (HTML and feeds) against
+  the same podcast aggregated and republished, then make them pass
+  via changes to `aggregatepost.impl` and [[plugins/aggregate]].
