RDFa introduction and codelabs for libraries

Posted on Fri 27 June 2014 in Libraries

My RDFa introduction and codelab materials for the ALA 2014 preconference on Practical linked data with open source are now online!

And now I've finished leading the RDFa + schema.org codelab that I've been stressing over and refining for about a month at the American Library Association annual conference Practical linked data with open source preconference. Long story short, most people got about as far as I expected (part-way through the first exercise), but they all got through the initial hurdles and learned enough to keep learning on their own. My hopes are that this leads to:

  • the implementation of structured or even linked data in existing systems, for those that at least have systems that give them the ability to edit their HTML templates
  • the addition of linked data to library web pages the next time they get refreshed or redesigned (it happens pretty often!)
  • some patterns of implementation, so that we hopefully arrive at a relatively standard way of marking up the same metadata (given the many alternatives that we have just within schema.org for something like a publisher)
  • when tweaking templates for display or design purposes, to avoid mangling existing structured data that a system like Evergreen, Koha, or VuFind publishes by default
  • more awesomeness in the world of library metadata!

Oh, and for posterity, I temporarily marked up this page to link to our pizza order form as a really lame short URL service, and as I did that impishly polluted the schema.org vocabulary with the new type PizzaOrderPreferences. I don't think that's going to make it into the official vocab though! The code was:

 <p vocab="http://schema.org/" typeof="PizzaOrderPreferences">  And <a href="http://doodle.com/exampleblahblah" property="url">order pizza here</a>.</p><p>If our pizza order doesn't get gamed, that just shows how few people visit my blog!
