Hello everyone,
We would like to thank the Spanish Drupal Association for editing and uploading a video of our presentation of Patterns at DrupalCamp Spain 2012: http://vimeo.com/61432578
Please notice that the explanation about the architecture refers mostly to the principles behind version 7.x-1.x, and the discussion about how to address the issue of dependencies was translated into the semantic validation system developed for version 7.x-2.x. However we consider it can be a very useful resource to get an introduction to Patterns.
You can also find the whole set of slides at: http://www.slideshare.net/drozas/automating-drupal-development-with-patt...
A more updated version of the slides for version 7.x-2.x we employed during our presentation at DrupalCamp London 2013 can also be found here: http://www.slideshare.net/drozas/patterns-dclondon2013
We hope you find all these resources useful!
