Syntax
Description
The rev
attribute is essentially the reverse of the rel
attribute. The rev defines what this
document is in relation to the document to which it links (as defined in
the href attribute). To put this in colloquial terms
(note that these values are not real values!):
rel= "This is what I call that fellow over there."rev= "This is what that fellow over there thinks I am."
Example
In the following example, the link
to the cakes list is defined so that the
rel(ationship) shows that the linked document is a
page that’s classified as a "product-line". Meanwhile,
the rev attribute indicates that the linked page
would treat the referencing page as an index of menus (or
"menu-index"):
<p>You can try our <a href="cakes.html" rel="product-line"
rev="menu-index">lovely range of cakes</a>.</p>
Value
This attribute can take any
value—even a series of space-separated values. Some conventions are
beginning to form around the use of the rel
attribute (there’s more about this in Microformats).

The support charts
for this element show that there’s no support, as no browser renders the
links that use this attribute any differently from normal links. The real
value of adding a rev (or
rel) attribute is gained either by utilizing it to
add functionality via JavaScript and the DOM, or through a centralized web
service of some kind that may be able to make use of the attribute’s
content (perhaps for analytical purposes, or for refining search
results).
