A while back I had a project in which this feature would have been very useful. If new hooks go in to make this possible, please email the group so others may implement it.

Markus and Thomas,
Yes, I'm aware of http://ontoworld.org/wiki/Semantic_MediaWiki (I believe I referenced it in my original post + cc'd the semediawiki list(s)?).
I call my project 'semarbtri' to distinguish it from the existing Semantic Mediawiki project.
My biggest beef w/ Semantic Mediawiki (the reason I'm writing my own extension) is that you can only add semantic information for the page you're editing.
For example, on the Lucy page, you could say:
Lucy has a younger brother [[has_brother::Linus]]
However, you couldn't add any semantic information about Linus on the Lucy page. Instead, you'd have to create a new page for Linus, and add the semantic information there.
This can be really tedious if you're listing all the characters in a comic strip (for example)-- you have to create pages for each one, instead of just including the semantic info when you list them.
In my opinion, this is why startup wikis end up w/ so many blank pages.
I think having a plugin that lets you add info to other pages would be really helpful.
That's an interesting point. Semantically, a different person should be on a different page, but you make a good point that in practice, that isn't always the best option. I would suggest adding your feature to the existing extension, rather than reinventing the wheel, though.
It would be not to hard to add something like this to SMW, even in a fairly modular way (although the DB layout obviously would need extension). The reason that we did not do it is that we felt that it impairs maintainability (if you discover a wrong search result, what page do you edit to fix it?), and that it might lead to a "semantic shadow wiki" (people creating very complex structures on a single page, which is hard to control; e.g. locking the page on Lucy during an edit war [controversial girl, that Lucy] still would not prevent people to add the disputed information elsewhere). I know that there are all kinds of ideas to prevent this, but this certainly adds some complexity.
Anyway, rebuilding everything from scratch just to add this feature seems to be a lot of avoidable work. We can also assist you with extending SMW (by providing extension interfaces etc.). But do as you like.
