Atom Feed ID should not be the article.url

Atom Feed ID should not be the article.url

Using the post url as the atom id is not really the best practice. If the permalink changes (e.g. due to a typo) then the atom id will also change resulting in this post showing up again in feed readers (and other issues).

Once set, the ID should never, ever change no matter what.

Perhaps when your rake task generates the post, you can generate an appropriate (e.g. uuid) atom id in stuff it into the metadata of the post (and teach the user to never change this id).

See :

Start with the rake task that generates posts and the Atom feed code, then inspect how article.url and post metadata are used for the feed ID. The work is done when a generated Atom ID remains unchanged if the post permalink changes, with the ID stored in post metadata.
