I've now created a test site for a semantic MediaWiki that lets you
put the triple (x,R,y) anywhere, not just on page x:
This is a very neat idea. Is this integrated in Semantic MediaWiki
or is it a separate extension? If not, and given that SMW also uses
triples, although using the article's name as "x", shouldn't be easy
for you to integrate your idea in SMW?
