Robert Newson commented on COUCHDB-259:
---------------------------------------


+1, I'd like somewhere to store md5 or sha1 values for the attachments too. I attempted a local hack, and while I can manage it on retrieval, my attempts to get it into the stored file failed.

> I suggest the ability to store arbitrary data in line with single attachments to a doc. The mooted use is to store metadata about that attachment.
> For example, a current attachment:
> m['_attachments']
> => {"yamanote.jpg"=>{"content_type"=>"image/jpeg", "stub"=>true, "length"=>382613}}
> Desired behaviour is to be able to insert persistent metadata like so:
> m['_attachments']
> => {"yamanote.jpg"=>{"content_type"=>"image/jpeg", "stub"=>true, "length"=>382613, "width" => 800, "height" => 600, "md5" => "95de7a118ee28824afa8d2ad8fe5819f"}}
> And many other use cases according to media type.
