Rel Examples

This page is for documenting real world example uses of rel attributes, including established HTML4 and microformats values, drafts, exploratory discussions, and external examples which could potentially be used in microformats.

Purpose and Scope

  • Use The microformats process first. Rather than listing any new rel attribute uses here, if there is a desire to actually rigorously develop the functionality behind such rel attributes into a microformat, then the The microformats process should be followed with that functionality in mind, rather than a paticular rel attribute value.
  • Reference URLs to external uses with potential. It may not be clear what the value is of documenting external rel examples outside the attempt to develop any particular microformat. However, it seems reasonable to have a placeholder for such documentation as a reference of sorts to existing real world example uses to be considered unless it proves counter-productive or attempts to bypass the The microformats process. Examples (and any documentation thereof, including implementations) which have been considered and rejected should be moved to the rejected-formats page since they no longer could "potentially" be used in microformats.
  • Proposing rel attributes is inappropriate. Any "proposed rel attributes" would very much be bypassing the The microformats process and thus are discouraged. Pursue the The microformats process for development of a solution to the problem area, rather than leaping to the specific technical solution of using a rel attribute value.

The following are lists by specification / origin.

For a flat alphabetical list of rel formats, brainstorms, POSH uses, see: existing rel values.

HTML4

The HTML4.01 spec defines several link types which are values that can be used in rel (and sometimes rev) attributes. See existing rel values for an annotated list.

microformats

Several microformats use rel values. These are a useful place to start to understand good uses of rel values.

In addition, though it uses rev instead of rel, Vote Links is listed here for completeness.
