What is a good example to map "Enclosure" to?

If you get feedback on this I'd love to hear it.

A filefield is a good example: http://drupal.org/project/filefield

Enclosures are just URLs to media on a remote server. Simply map the URL to a CCK textfield then use SWFTools module to theme the URL to a suitable video/audio player etc.

Also take a look at emfield as an alternative to the above, although it requires a patch to add emfield fieldtype mapping to Feeds.

As another example, I am mapping enclosures from a feed of a flikr photoset to an imagefield and it works fine. Needed Enclosure support to get at the large image instead of the image you get via the URL mapping.

I believe the discussion for this issue is too simplistic. One of my sites is a podcast & blog directory which has a hundred or so feeds right now and could have a lot more over time. It's using FeedAPI

..so.. one thing I've seen after looking at a dozen or so podcast RSS feeds is that "Enclosure" is not enough in podcast feeds. Podcasts can also include iTunes or other meta data. Unfortunately there is no consistency between the feeds I've looked at.

..so.. I end up having a lot of per-feed custom mapping because there is no consistency. Unfortunately Feeds doesn't support per-feed custom stuff.

That'll work somewhat. If you want the aggregated items to become a podcast in their own right there is a need to have the Enclosure data become an Enclosure in generated RSS feeds. Also the Enclosure tag has four data items, the URL (as you said), the MIME type, the size, and a description. There's a module whose name I'm forgetting at the moment which will do this ("RSS Remote Enclosures"?) but it will need some work. I think it should a) become a CCK field (or in D7 a Field), b) have a mapper that handles podcast elements from a feed

Right.

That's one way of doing it. I would argue that it is the parser's responsibility to create consistency.

This is exactly what e. g. simplepie or common_syndication_parser are already doing for source elements like e. g. title, description, author, url, guid, etc. It's called 'normalization'.

Enclosures aren't normalized well, I hear (not using them much myself). Plan of action to fix enclosure handling would be:

1) identify common denominator (= normalized enclosure)
2) write parsing code that maps cleanly to these common denominator (most likely in common_syndication_parser).

Thus you don't have to use multiple mappings per feed and we actually get to share our knowledge on 'where is this thingy on feed x' beyond our web site's confines.

I installed simplepie parser to use enclosuers, mapped enclosure to body field, just for testing and then importing feed, enclosure looks like

<div class="enclosure"><img src="moz-icon://goat?size=16&amp;contentType=image/jpeg" class="type-icon"/> <a href="http://www.24sata.hr/slika-rss/suspendirali-dva-policajca-jer-su-madaru-uzeli-50-_200x150n_125346.jpg">suspendirali-dva-policajca-jer-su-madaru-uzeli-50-_200x150n_125346.jpg</a> (JPEG Image)</div>

but i get nothing in body field? should work, at least put html code, input format is set to full html but nothing is parsed to body, any ideas why?

When i switched from body to filefield its working fine, problem is enclosure isnt just url its " An array of enclosures attached to the feed item." so its an array and then you need to pass it to some field with parser for array i guess. so budda comments are wrong about that it can be any field.

Dont know how filefield handles videos, guessing you have to have some media field for this in additions as filefield would probably just display link of your video.

#10: single value target fields should just grab the first item of an array and display it. If that's not the case, please open a separate issue.
