I understand that this is a port of a DAML note.



1) duration

In the migration from DAML to OWL, the WG identified that the semantics 
of xsd:duration was unusable, and say that it *SHOULD NOT* be used.

See
http://www.w3.org/TR/rdf-mt/

(note this text originated in WebOnt)

The SWBPD's datatype note addresses this issue

http://www.w3.org/TR/2005/WD-swbp-xsch-datatypes-20050427/#section-duration

The time ontology should be updated in line with the advice there.

2) congo.com

W3C documents normally use the convention of taking examples from the 
reserved domain example.com, e.g. congo.example.com. This avoids 
annoying the owners of congo.com.

3) URIs versus qnames

Code such as <tz-us:EST> is incorrect in N3.
Either use tz-us:EST, with some indication somewhere that tz-us is being 
used as a namespace prefix, possibly giving its namespace URI, or at 
least saying somthing about the namespace.
Or give a full URI e.g. <http://example.com/tz/us#EST>
