title: Syndication research notes
---

I am currently plowing through the Wayback Machine to look for obsolete
syndication formats.  This page is just here to list a lot of links that
I still need to check out, maybe to get even more specs in this wiki.

## XML namespaces

Various namespaces that can be found mostly on RSS/Atom feeds, and that I want
to look into at a little bit more. I'll probably post about those on
[RSRSSS](/rsrsss/).
