Oh dear, not another one!

I'm working on a program called Memesh (Cocoa, Obj-C) to do something 
rather similar. Basically the interface searches and displays objects, 
deciding on "display plugins" to use based on the object type. The 
generic object displays arbitrary metadata and a bunch of text (sorta 
like an email message) but you could make custom plugins for people, 
music, etc. to display the properties in a different way.

I guess I don't understand the problem. You display an object and its 
properties (and possibly reverse properties). If custom views need more 
information than that they simply request it. Otherwise it's just a link 
to some other object which you can examine similarly.

I guess this leads one to take a flat view of things ( {:x 
:workPhoneNumber "y" .} rather than { :x  :work [ :phone [ :number 
"y" ]]. }) but I think that's a good idea anyway.
