Proposed response to Michael Grove
(Note the current editors draft of imports-011 still has a known bug, it will 
be updated before the response is sent to Michael).

<<

1)
The test file
http://www.w3.org/2002/03owlt/imports/premises001

is in OWL Full because the URIref node
http://www.w3.org/2002/03owlt/imports/premises001

is the subject of a triple (the owl:imports triple), but has not been given 
a type.

To further clarify this we have added a new test imports-011 which is similar 
to imports-001 but with the missing triple. Hence 
http://www.w3.org/2002/03owlt/imports/premises011
 is in Lite not Full.
(See the editors draft:
http://www.w3.org/2002/03owlt/editors-draft/draft/proposedByFunction#imports-011
)

2)
http://www.w3.org/2002/03owlt/miscellaneous/consistent102

The file is in OWL DL not OWL Lite.

An analysis of sections 2 and 4 of S&AS shows that in OWL Lite there are no 
blank nodes with explicit type owl:Class, except those which also have 
explicit type owl:Restriction

This is echoed in OWL Reference:
Sec. 8.3 of Reference also contains the following constraint on OWL Lite 
(see just below the intersectionOf bullet):

[[
* the object of rdf:type triples be named classes or restrictions;
]]

To further clarify we will add the following statement concerning OWL Lite to 
sec 8.3 of reference.
[[
Blank nodes representing classes should be of type owl:Restriction.
]]


Thanks very much for this feedback, please send more.

Please respond, copying public-webont-comments@w3.org, indicating if you 
withdraw the comment that tests
 http://www.w3.org/2002/03owlt/imports/Manifest001
and
 http://www.w3.org/2002/03owlt/miscellaneous/Manifest102
are incorrect. Please also indicate whether you are satisfied that the changes 
we are making adequately address your difficulties.

yours

Jeremy Carroll
