-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.
+## Status
-[[!toc]]
+[[!template id=gitbranch branch=schmonz/fancypodcast author="[[schmonz]]"]]
+[[!tag patch]]
-## Design
+Nothing new since 2013/07/21 [[merge|done]] to `master`.
-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.

+## Future improvements
+
+### iTunes fancy podcasting
+
+* [iTunes-specific tags](https://www.apple.com/itunes/podcasts/specs.html)
+ appear to be RSS-only
+ * Can we always include them in RSS feeds, or would that break
+ 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: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
+ * [mediainfo](http://mediainfo.sourceforge.net/) is way slower
+ * Cache computed durations as pagestate
+* [Podcast Feed Best
+ Practice](https://github.com/gpodder/podcast-feed-best-practice/blob/master/podcast-feed-best-practice.md)
+ from the gPodder folks
+
+### 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
-### Completed
-
-* 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`.
-
-### Must-have (for [[schmonz]], anyway)
-
-* Write failing tests for the desired RSS/Atom behavior, then make
- them pass, probably via changes to `{atom,rss}item.tmpl` and
- [[plugins/inline]].
-* 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.
-* 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.
+* 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).
