I'm not so sure I care about the "well you should be modeling it
different" thread or inference support or "strong typing".   I was under
the impression that data-typing serves as a mechanism to identify the
process to convert a string representation into a particular value.  

That typing data is either built into the processing software, inferred
from schema or explicit in the data...

In the explicit case, it would seem weird to me that all other typed
literal values (int, float, "number", "base64-jpeg", &c.) would use the
datatyping mechanism, whereas booleans specifically and strangely would
use URIs.

As counterpoint to your "we don't need URIS anywhere!" msg [1], should
all values become a URI?

 http://example.org/xsd/dateTime/2005-03-17T08:58:00-05:00 ?
 http://example.org/number/123456.789 ?
 data:image/png;base64,ABC123[...] ?

Why are booleans special?
