Wooh!  What about some simple (retract ... assert) transactions to the semantic
cloud as the basis for changing schema?   "Cached schema" is just another term
for semantic memory.  Take a look at the diagram at
http://robustai.net/mentography/perdicaments.gif .   You guys seem to be making
the assumption that you can ever make this cloud coherent for everybody
globally.   I don't think you can.  The only way for a ( person / company /
government / organization) to find coherence, is for it to collect its own
triples somewhat isolated them from the rest of the incoherent cloud.

Don't fight fragmentation, learn to love it, but get your own shit together.
