| == Abstract ==
| |
|
| |
| RelCite is one of several [[elemental-microformat|elemental microformats]]. By adding <code>rel="cite"</code> to a hyperlink, a page indicates that the destination of that hyperlink is an authoritative source or a precedent to the current page. RelCite may be used whether an author cites by quotation:
| |
| <pre><blockquote>Our liberty depends on the freedom of the
| |
| press, and that cannot be limited without being lost.
| |
| <a href="http://en.wikiquote.org/wiki/Thomas_Jefferson" rel="cite">
| |
| Thomas Jefferson</a></blockquote></pre>
| |
| or by reference only:
| |
| <pre><a href="http://example.com/joeschmoe/article/99/" rel="cite">
| |
| Joe Schmoe's latest rant</a> is wrong, wrong, wrong...</pre>
| |
|
| |
| RelCite is also reversible, i.e. the syntax <code>rev="cite"</code> indicates that the ''current page'' is an authoritative source or a precedent to the ''destination page''. This syntax may be useful when an author wishes link to off-site discussions of his own content.
| |
|
| |
| The linked page MUST exist, and it is the linked page, rather than the link text that defines the citation.
| |
|
| |
| RelCite is fully compatible with other microformats such as [[rel-nofollow|RelNoFollow]] and [[vote-links|VoteLinks]] to indicate a very specific relationship: <code>rel="cite vote-against nofollow"</code>
| |
|
| |
| == Scope ==
| |
| rel="cite" is specifically designed for "citing" content, typically web pages (or portions thereof, like blog posts). "Cite" is defined as "to quote or refer to as a precedent or authority."

| |
| == Citations As Interactive Metadata ==
| |
| <code>rel="cite"</code> hyperlinks are intended to be visible links on pages and posts. Note that other markup may be used to indicate citation:
| |
| <pre><blockquote cite="http://en.wikiquote.org/wiki/Thomas_Jefferson">
| |
| Our liberty depends on the freedom of the press, and that cannot be
| |
| limited without being lost.<cite>Thomas Jefferson</cite></blockquote></pre>
| |
| but User Agents are not compelled to expose a link to the cited resource. Hyperlinks are preferred because they afford the user easy access to the cited resource.
| |
|
| |
| == Implementations ==
| |
| A theoretical implementation of RelCite could enable users and machines to determine the degree of separation of a given resource from a Primary resource in a "citation chain" where "Primary" denotes the first, original or most authoritative online resource for a unit of information or a discussion. By following <code>rel="cite"</code> links one can expect to converge on topical Primary sources; contratriwise, following <code>rev="cite"</code> links should bring one to resources of increasingly distant relation to one Primary while exposing other citation chains in the process.
| |
|
| |
| It would be advantageous for implementations of automated linking systems such as Trackback and Pingback to generate <code>rev="cite"</code> links on cited resources.
