As you may, or may not, have noticed, I’ve been integrating various pieces of metadata into the site, primarily into each individual post. Eventually I’ll remove the ‘meta’ option for each page, and just provide a machine consumable RDF/XML option — the humanly readable components will show directly.
Right now I’m creating a plugin in that pulls the links within a post and adds these into the metadata as references associated with the post. I’ve also added a form that allows me to add references that aren’t linked in the post (and which are printed out at the end of the post).
I’m playing around with tags and other odds and ends, but I wish I could find the right combination of data and implementation to really effectively demonstrate how all this holds together.
