Semantic Mediawiki allowing semantic info for non-current page?

This sentence provides semantic information on several objects:

"Bob has two sons, Bill and Jim, who married Mary and Katy respectively. Bill and Mary have twin girls, Jill and Amanda."

In a normal semantic wiki (eg, semediawiki), you can only give semantic information for the page you're on.

Is there a semantic mediawiki that lets you provide information on multiple items at once?

Sample syntax might be:

Bob has two sons, [Bob:son:Bill] and [Bob:son:Jim], who married 
[Bill:wife:Mary] and [Jim:wife:Katy] respectively. Bill and Mary have 
twin girls, [Bill:daughter:Jill] [Mary:daughter:Jill|] and 
[Bill:daughter:Amanda] [Mary:daughter:Amanda|]. [Jill:twin:Amanda|] 

(things li开发者_如何转开发ke [Mary:daughter:Jill|] create a semantic triple, but print nothing)

I'm of course aware of http://davidbu.ch/mann/blog/2010-03-12/mediawiki-extensions.html but that is a little buggy, builds pages in real-time (a little CPU intensive), and doesn't have any community support (no insult to David, of course).

For efficiency, when you edited the "Bob" page above, it would update Bill, Jim, etc. In other words, the wiki could render "Bill" w/ the regular number of MySQL queries, not extra ones for semantic information.

An alternate approach I considered is creating "data" pages that aren't associated with any wiki page. Example:

[Bob:text: has two sons, [Bob:son:Bill] and [Bob:son:Jim], who married 
[Bill:wife:Mary] and [Jim:wife:Katy] respectively. Bill and Mary have 
twin girls, [Bill:daughter:Jill] [Mary:daughter:Jill|] and 
[Bill:daughter:Amanda] [Mary:daughter:Amanda|]. [Jill:twin:Amanda|]] 

The page above would add text to Bob's page, and semantic information to Bob, Bill, Jim, etc pages.

The nice thing is efficiency: you could statically render all wiki pages.

I realize there's controversy re whether this would be a good thing. For now, I'm looking to do it technically and worry about the other stuff later.

It looks like you should be able to pay David to update his extension, maybe he could even make it do what you want it to do.

Semantic mediawiki isn't my specialty, but alternatively you could probably do this with Templates, since they are basically '"data" pages that aren't associate with any wiki page.'
