Great list Len. Here are some I would suggest modification to:

Specify mappings between multiple standard controlled vocabularies wherever
their domains of interest overlap. (This helps vocabularies to grow)

Provide multilingual mappings for terms and definitions

Specify region and timeframe over which domains and roles apply. (What dates
will George Bush be leader-of-country? Which country? How does this differ
from being leader of Texas?)

Domain dependent mappings are required to understand the relationship
between equivalences (US lbs and metric kg being a case in point, not to
bring up the subject of the speed of Mars landers!)
