say that we need Microformats. Do you catch yourself asking But Why?
Good question. Right now the Microformats movement is dealing with a bit
of a chicken-egg problem due to a lack of tool support. Without tools to
make microformat creation simple for content publishers and to make
microformats more usable and visible to content consumers, it is
difficult to see the point of the effort. The effort / reward scale is
currently tipped heavily towards the effort side.
That may soon change as Microformats start taking over the web. In
preparation for an article I am writing on the topic, I have been doing
some thinking and reading up on Microformats. I won’t spoil the article
by discussing Microformats in much detail here, but instead will
highlight one microformat and my effort to make it more visible.
Do not reinvent the wheel!
Remember, Microformats are not about trying to reinvent the wheel. In
fact, it is a key principle of the Microformat philosophy to build on
what already exists. For example, even before microformats there was an
initiative called XFN (or XHTML Friends Network). The idea is to add
semantic information to web links in the form of the
rel attribute to
This existing format has been adopted as a microformat. When linking to
a friend’s blog or website, for example, you might add the following
<a href="https://haacked.com/" rel="friend met">...
This incidentally creates a network that is indexed by XFN crawler. But
how does the average visitor to your site even notice this? Unless they
view source, they won’t. This sort of goes against the Microformat
principle of focusing on humans first and machines second. Better tools
are needed to highlight interesting microformats to end users.
So let’s expose our friends

As more web publishers start adding microformatted content to their
sites, I think we’ll see a proliferation of these type of scripts
targetting this content.

indexOf with regular expressions)
What the script does is look through your html for links using the XFN
microformat. It then places a little icon next to links that express a
relationship as well as a special tooltip that lists the relationships
info. But rather than talking about it, I should give a demo. Again, I
will have to ask you to try this out in a browser since most aggregators
I know. Go ahead and move your mouse over them. Go on now.

How to Use
2. Include the XFNHighlighter CSS file (or cut and paste these styles
into your own stylesheet).
<link rel="stylesheet" href="css/XFNHighlighter.css"
type="text/css" media="screen" />
3. The CSS references an image friends.png in the images directory.
Make sure that image exists or change the CSS to point to an appropriate
image. This image is placed next to the link.
1. Add an appropriate
rel="value" when linking to a friend or
acquaintance. Check out the list of relationships from the XFN
