Step by step MQL with Jimi Hendrix

Step by step MQL with Jimi Hendrix

This is a document teaching basic concepts of MQL. The examples show step by step how you can extract all the information on a particular Freebase topic. (Jimi Hendrix)

TODO:
  •  Finish the examples!
  • Convert from a static document into a real MJT application which automatically runs, formats and diffs the results.
Notes:

When I show developers Freebase and the query language MQL, the first thing they often try to do is extract all the info they can out of the database for a generic topic.

This is actually quite a good learning experience, as you have to learn lots of MQL concepts:

  • How “*” expands (default values v objects, type specified or not)
  • Multiple queries v nested queries
  • Reflection

I had been keeping my own notes, but I thought they might be worth sharing so I whipped up a nice stylesheet and here they are.

Still lots of uncompleted TODO points but I’d be interested in your feedback. Is this something worth working on?
