This is exactly why we should be using N3 to represent the modelling  
on the wiki. The syntax Bernd used is not standard, nor clear.

Not really. In N3, you can use the abbreviated syntax to represent a  
subject too. It's just a URI after all. It would be equivalent to:

<http://wiki.oasis-open.org/office/ExampleDocument#task> <http:// 
wiki.oasis-open.org/office/ExampleDocument#description> "..." .

for the past two months.
