I think that you can insert a way to create relations between pages (resources) very simple and powerful.
Very similar to the square brackets [...] method for links, you can declare relations as the follow example:
Imagine you are writing a wiki page and in place of a significative word ,for instance the word "house", you can write this:
[house -> contain ->room]
So, like the use of " [...]" for links, if pages exists are linked otherwise it propose to create them.
This contents can be easily translated to
RDF triples. Your wiki can became a "shortcut" to collect and create knowledge in a free
RDF way.
There is one limit: "Only one triple for a word in one page" but we can think solutions easily....
Sorry for my bad English.
