Inspiration and Acknowledgments

Thanks to everyone who has given feedback on VoteLinks. Thanks especially to EtanWexler, who provided the first really good documentation that VoteLinks should be using 'rev' instead of 'rel' (see votelinks-faq), and John Allsopp who similarly challenged the use of 'rel', and helped co-author the rel-faq exploring questions and issues about the use of the HTML4 'rel', 'rev' attributes and linktypes in general.


Indexing and tracking applications treat all links as endorsements, or expressions of support. This is a problem, as we need to link to those we disagree with as well, to discuss why.


VoteLinks is an elemental microformat, one of several microformat open standards. We propose a set of three new values for the rev attribute of the <a> (hyperlink) tag in HTML.

The new values are "vote-for" "vote-abstain" or "vote-against", which are mutually exclusive, and represent agreement, abstention or indifference, and disagreement respectively.

A link without an explicit vote 'rev' value is deemed to have value "vote-for" or "vote-abstain", depending on the application.

Additional human-readable commentary can be added using the existing 'title' attribute, which most browsers show as a rollover.


<a rev="vote-for" href=""  
   title="neat spoof">Raging Cow</a>
<a rev="vote-against" href=""  
   title="nasty corn syrup drink">Raging Cow</a>

Deprecated: Using 'rel' for VoteLinks

A previous draft of the specification used the 'rel' value instead of the 'rev' attribute. Analysis and feedback has demonstrated this to have been inappropriate use of the 'rel' attribute, when the 'rev' attribute was much more important. See the rel-faq for more details.

Implementations MAY support links with the VoteLinks values in the 'rel' attribute for backward compatibility with any existing VoteLinks content.

Authors MUST NOT use 'rel' for VoteLinks values.

Examples in the wild

This section is informative.

The following sites have implemented VoteLinks , and thus are a great place to start for anyone looking for examples "in the wild" to try parsing, indexing, organizing etc. If your site marked up with VoteLinks, feel free to add it to the top of this list. Once the list grows too big, we'll make a separate wiki page.

  • Christian Hess uses CSS styles at his site (in Spanish) to highlight "vote-against" links, like in this article. Note: you must be using a modern, standards-compatible browser, such as Firefox or Opera.
  • Tom Morris has vote links on links (based on tags "vote-for", "vote-against" and "vote-abstain").
