Yes, I see. The dependencies are as follows:

-> store page edit times etc. automatically in SMW, so it can be queried like 
other properties

-> add new built-in properties for these features

-> create a better extendable mechanism for declaring new custom built-in 
properties, get rid of the current hard-coded "special property" architecture

-> have a new class to represent properties internally, both user-defined ones 
and built-in ones (currently normal properties are represented by Title 
objects while built-ins have hard-coded numbers: not uniform, not extendable)

-> store built-in properties not in a special way like now, but store them 
like the other properties (otherwise one could not query them); change the 
storage engine for this purpose


I think I have it in my mind how to proceed; I just need to find the time to 
do it. I will *try* to get it done for SMW 1.3. I also note that the above 
would entail some changes in the SMW API (e.g. when using new objects to 
represent properties). But overall things would get simpler (no more special 
functions for special properties), and I assume extension developers would 
also welcome a better mechanisms for making pre-defined properties.
