If I had a) time and b) money, I would certainly be considering taking the classes for the Certificate in XML and RDF-Based Systems at Library Juice Academy. It starts next February, and comprises 6 4-week sessions at $175 a pop. It’s taught by Robert Chavez, who has a PhD in Classical Studies and worked at Perseus for 8 years. Course descriptions for each session are available at the link, and they seem pretty hands-on – like you might actually build stuff, not just talk about it. Library Juice does continuing education classes, all online and asynchronous, for library professionals.
Note I have no personal experience with Library Juice and don’t know Robert Chavez, but boy those classes look just right for someone who’s interested in LAWDI and Linked Open Data and is not a great self-starter in terms of teaching oneself technical stuff (i.e., me). If only I had a) time and b) professional development money.
