   * This is optional if there are multiple workshops per year, in which case, the following applies: abbreviation of the event the workshop is part of e.g., if co-located with the "International Semantic Web Conference", use `iswc-`. For stand-alone events, use an abbreviation e.g., if the event is held at some University, use `uoa-` (for "University of Acme"). Full URL example: `http://semstats.org/2013/iswc-call-for-papers`. This pattern is not likely to happen in the forseeble future, however we document it here in any case.

 ## How to generate the proceedings
 This is one of the processes we can use to generate the proceedings. I broke it down as close as possible; it is manual, but simple enough. If you prefer otherwise, see ceur-make for the alternative methods. We should let the authors retain the complete copyright.
