What exactly does the "Result Formats" row mean? How does wikibase have 0 result formats? What is a result? What is a format?
Topic on Manual talk:Managing data in MediaWiki
Maybe we should call it "inline querying"?
What is special about SMW (and also Cargo) is, that you can on very wiki page you want query the available data and then decide if you want to do a |format=table for a tabular display or |format=json for an export or |format=calendar for a calendar display.
In my understanding this is a major difference to Wikibase, because afaik you need to do sparql queries or use external query/display services. Which are great, but a main difference IMO.
