rel-registry
<entry-title>rel registry</entry-title>
The microformats wiki does not yet have a formal rel value registry, however we have the most comprehensive documentation of existing-rel-values currently which performs quite well as a rel registry, perhaps even better than any other "official" attempts at rel registries out there.
stable rel values
The formats section of the existing-rel-values page can be used as a list of stable/dependable rel values.
draft rel values
The proposals section of the existing-rel-values page can be used as a list of rel values with reasonably well written proposals.
provisional rel values
The brainstorming section of the existing-rel-values page can be used as a list of ideas / simple proposals for rel values that merit further research and development (and possibly documentation as drafts) per the microformats process
additional rel values
The existing-rel-values page contains additional sections/clusterings of rel values that have been documented in the wild. Some of these may merit brainstorming/provisional registration and further development.
There is also documentation of dropped and rejected rel values for the sake of thoroughness and to hopefully avoid having them be unnecessarily re-proposed (without at least following up on why they failed in the first place.)
new rel values
If you wish to develop a new rel value, please follow the microformats process. Feel free to add possible rel values to the brainstorms section, but be sure to follow-up quickly with a page for the rel value itself explaining it in more detail, as well as email the microformats-new mailing-list.
