+
+In summary, the branch preserves ikiwiki's existing podcast behavior,
+adds more featureful behavior, and has been tested to work well in
+some common podcatchers. I believe it is ready for review and
+possible integration, and I'd like to get feedback to that effect
+(or to the contrary) before making further enhancements. I know
+[[joey]]'s the final arbiter here, but I'd appreciate any qualified,
+critical eyes ([[smcv]]?) raking over my diffs. --[[schmonz]]

 ### Must-have (for [[schmonz]], anyway)
 
-* Enrich podcast feed metadata (some of which is iTunes-specific,
-  though I'm not aware of it causing any problems for other
-  podcatchers, and in fact some of them may also use it).
-* Subscribe to a fancy feed in some common podcatchers and compare
-  display details against a reference podcast.
-* Compare feature-for-feature and feed-for-feed with
-  [tru_podcast](http://www.rainskit.com/blog/542/tru_podcast-a-podcasting-plugin-for-textpattern),
-  which is what [[schmonz]] will be migrating from.
 * 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 the feeds validate.
+    * Whether [[tips/howto avoid flooding aggregators]] suffices for...
+        * Converting a simple podcast to a fancy one.
+            7. Set up a non-production copy of one of my podcasts.
+                * Manually test that feeds match production.
+                * Subscribe to the copy in `r2e`, iTunes, Downcast.
+            7. Try migrating the copy from simple to fancy.
+                * Document the steps I take.
+                * Make the feed readers update.
+                * Document what happens for each of them.
+        * Migrating a fancy podcast from elsewhere into ikiwiki.
 * Verify that _all_ the tests pass (not just my new ones).
 
-### Nice-to-have
+-----
 
-* 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.

+* [iTunes-specific tags](https://www.apple.com/itunes/podcasts/specs.html)
+  appear to be RSS-only
+    * If they work in Atom, teach `inline` to optionally iTunesify RSS/Atom.
+    * Else, add `itunes` as a third kind of feed (RSS plus more stuff).
+* Notable tags for feeds:
+    * `itunes:subtitle`
+    * `itunes:author`
+    * `itunes:summary` (same as `description`)
+    * `itunes:owner` (includes `itunes:name` and `itunes:email`)
+    * `itunes:image href=''`
+    * `itunes:publisher`
+    * `itunes:category text=''` (can contain subcategories)
+    * `itunes:keywords`
+* Notable tags for entries:
+    * `itunes:duration`
+        * [[!cpan Audio::TagLib]] might be fastest, if present and applicable
+        * [ffprobe](http://ffmpeg.org/ffprobe.html) is reasonably fast

+### Fancy podcast aggregating
+
+* 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]].
+
+### Other ideas
+
+* Optionally specify the enclosure's:
+    * MIME type, in case `File::MimeInfo` guesses wrong.
+    * Duration, in case `ffprobe` guesses wrong.
+* Optionally specify enclosures outside the wiki:
+    * Some people don't want to store big unchanging files in the VCS.
+    * Other people like [podcasting found media](http://huffduffer.com/about).
+    * We'd have to download the file just to compute some metadata
+      about it, and then somehow not frequently re-download it.
+* Configurably generate additional subscription links (such as
+  iTunes) alongside the RSS/Atom ones in [[plugins/inline]].
+* Support Apple's "enhanced podcasts" (if they're still relevant).
