I'm Bernhard Krabina, researcher, consulter and trainer at the KDZ - Centre for Public Administration Research in Vienna, Austria. Also, I am member of Open Knowledge, Austrian Chapter and Semantic MediaWiki enthusiast.
In my opinion, SMW is a great OpenGLAM tool. The Vienna City Administration will release a huge wiki with ~ 40.000 pages in September. Details will be discussed at: https://semantic-mediawiki.org/wiki/SMWCon_Fall_2014
