>Good luck trying to find anyone knowledgeable in Semantic MediaWiki here

Well, OP is in luck. I happen to know a decent amount about SMW, and operate several Wikis where it is enabled.

OP, you're using Year:: but the name of the article won't be allowed if you set Property:Year to type Date, or artificially restrict the strings allowed for a string-type property.
