[OGDev] Adding microformats to the default templates

[Nick Burch]

Hi All

As part of my attempts to help people get as much metadata out of 
OpenGuides as they can, I've been going through the default templates 
(well, mostly node.tt and display_metadata.tt) adding Microformats.

For those of you who don't know about them, Microformats are simply a 
standard way of marking up parts of your page such that they have 
(enhanced) semantic meaning. You add a few extra bits of markup to your 
page, and suddenly all sorts of code out there can then get at the data.

The microformats I've used are:
   http://microformats.org/wiki/hReview
   http://microformats.org/wiki/hCard
   http://microformats.org/wiki/geo

You can grab the templates from svn, or see them in action on the 
cotswolds openguide (http://cotswolds.openguides.org/). Do shout if you 
have any thoughts/suggestions/enhancements around this.
