=== 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 [[VoteLinksFAQ]]), and John Allsopp who similarly challenged the use of 'rel', and helped co-author the [[RelFAQ]] exploring questions and issues about the use of the HTML4 'rel', 'rev' attributes and linktypes in general.

== Introduction ==
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.

== Specification ==
VoteLinks is an [[elemental-microformat|elemental microformat]], one of several [[microformats|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.

Examples:
<source lang=html4strict>
<a rev="vote-for" href="http://example.com/cheesevote"
title="Melt the cheese!">Do it!</a>
<a rev="vote-against" href="http://example.com/cheesevote"
title="Don't melt the cheese!">Don't do it!</a>
</source>

=== Deprecated: Using 'rel' for VoteLinks ===
A previous draft of the specification used the 'rel' attribute 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 [[RelFAQ]] 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.

== XMDP profile ==
The following is an [http://gmpg.org/xmdp/ XMDP] profile for the [[vote-links]] specification.

=== URLs ===
This profile is hosted as a separate XMDP file on microformats.org:
* http://microformats.org/profile/vote-links
* shortURL: http://ufs.cc/x/vote-links

=== Usage ===
Profiles are referenced in (X)HTML files in the <HEAD> tag, e.g.:
<source lang=html4strict>
<head profile='http://microformats.org/profile/vote-links'>
</source>

=== Profile ===
<source lang=html4strict>
<dl class="profile">
<dt id="rev">rev</dt>
<dd>
<a rel="help" href="http://www.w3.org/TR/html401/struct/links.html#adef-rev">
HTML4 definition of the 'rev' attribute.</a>
Here are additional values as defined in the
<a rel="help start" href="http://microformats.org/wiki/vote-links">
vote-links specification</a>
.
<dl>
<dt id="vote-for">vote-for</dt>
<dd>Indicates agreement with or recommendation for the referred resource.</dd>

== Implementations ==
This section is '''informative'''.
* Following a [http://jyte.com/cl/jyte-should-integrate-microformats-votelinks vote-links claim] [http://jyte.com/profile/brianellin.com Brian Ellin] implemented vote-links on [http://jyte.com Jyte] within less than 30 minutes.
* [http://moloko.itc.it/paoloblog/ Paolo Massa] created [http://moloko.itc.it/paoloblog/semantic_links/ SemanticLinks], a small Firefox extension that shows vote-for, vote-against links information. (Note the download links for SemanticLinks have been removed by the author.)
* Wordpress VoteBack (vote-link aware pingback and trackback) plugin is in testing at [http://redmonk.net/archives/2006/12/21/voteback/ VoteBack] ([[User:SteveIvy|Steve Ivy]]) - looking for testers!
* [http://folksr.de/ Folksr.de] - using VoteLinks to vote on the World Cup 2006
* [http://www.weboffate.com/ Web of Fate] - has VoteLinks for future predictions
== 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.

* [http://www.likeorhate.com/ LikeOrHate] uses Vote-Links all over the site, to rate anything, items, comments, users. Valid votes are Like, Hate, Whatever ("vote-for", "vote-against", "vote-abstain"). CSS is used to "check" votes so logged users can remember them later.
* [http://www.weboffate.com/ Web of Fate] Web of Fate uses Vote-Links for prediction probability scoring. Users can vote Agree, Disagree, Witness ("vote-for", "vote-against", "vote-abstain")
* [http://tommorris.org/blog/ Tom Morris] has vote links on del.icio.us links (based on tags "vote-for", "vote-against" and "vote-abstain").
