So I would add #4: 
#4: No namespaces exposed in GUI whatsoever
Matt


Apparently, we have two different questions:
 1. About exposing namespaces of say classes and relations during
browsing and editing. We may hide them ,which would work fine when there
is no any imported ontology. If there is an imported ontology then one
maight like to know from where definitions came. But certainly, looking
at the long URI may frighten anyone, including myself. 
If we decide that at this point we do not support imported ontologies
then #4 is just fine. If we want import, then the question is- how we
can specify node namespaces without messing up with repugnant URIs?

2. About specifying global namespaces which go to the heading of
ontology specification. There are many standard namespaces that could be
generated automatically, such as:
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
xmlns:owl=http://www.w3.org/2002/07/owl#

But how about specifying the base namespace, such as :
xml:base="http://wow.sfsu.edu/ontology/rich/Resources.owl"

We should also provide some metadata which probably can be in one place
with base namespace. If we would like to avoid seeing these
technicalities all the time, then perhaps tab pane (#3) is not right
thing. Then should it be done in a dialog which pops up before user
saves ontology, or separate popup dialog, or something else? 

Thanks,
Serguei
