[ikiwiki] / doc / todo / ability_to_force_particular_UUIDs_on_blog_posts.mdwn

When converting an existing blog to ikiwiki it would be useful to be able to preserve any existing UUIDs on posts, in order to [avoid flooding aggregators](/tips/howto_avoid_flooding_aggregators/).

Also, it should be possible to change the permalink (the Atom `<link>`) of a post (e.g. moving the content and leaving a redirector behind), while keeping the same Atom `<id>` (so that aggregators don't get confused).

Ideally UUIDs for [[blog]] posts should be chosen when the post is created, and frozen permanently by checking them in along with the content.

Perhaps ikiwiki's blogging functionality could be hooked up to the [meta plugin](/meta/plugin/), with a new meta keyword (uuid? feed-uuid? atom-uuid?) to achieve this.

> I'm not convinced that "uuid" is the best name for this functionality - the `<id>` in an Atom feed can be any URI, and one of the use-cases I have for this functionality in my own blog needs to have its `<id>` set to a URI that is not, in fact, its own address (it was a typo). "id" is a bit arrogant (forcing Atom terminology into a flat namespace!), "atom-id" is slightly misleading because it's also used for RSS... any ideas?
