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 process first. Rather than listing any new
relattribute uses here, if there is a desire to actually rigorously develop the functionality behind suchrelattributes into a microformat, then the process should be followed with that functionality in mind, rather than a paticularrelattribute value. - Reference URLs to external uses with potential. It may not be clear what the value is of documenting external
relexamples 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 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 process and thus are discouraged. Pursue the 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.
- vote-links - uses
revattribute
drafts
exploratory discussions
external examples
Links to documentation or specifications for these examples found in the wild would be appreciated!
