I've read through the prose; my comments are below.  I'm starting to
look at the packaging and try using the tests, but I'm not sure how
far I'll get with that.

For brevity my comments sometimes say "do FOO" when of course I mean
"I think you and/or the WG should consider doing FOO."

Some typos, but also it's pretty, um, awkward.  How about:

We plan to keep improving these tests until they are published as a
Proposed Recommendation.  Please let us know (at the comments address
below) if you find any errors.  We would also appreciate a note
describing your experience with these tests if you have developed an
OWL implementation.

                            ^^^^^^^^^^  subsidiary

Does that mean that if the documents disagree, the other one is

Clarify?  Perhaps by adding something like: "... since they are silent
on several important issues.  This document cannot be considered a
complete specification of OWL."

Has that practice been affirmed by the Comm team?

This seems to disagree with what I quote above, "The recommendation

explicitly or, for the larger tests, by reference to the test Web

names _like_ supportNNN.rdf ?

It seems odd to say each program outputs one word and may also output
warnings.   Describe stdout & stderr?  :-)

It took me a while to connect "this property" with its referrent.  How

   An OWL consistency checker MUST be <em>sound</em>: it MUST return
   Consistent only when the input document is consistent and
   Inconsistent only when the input document is not consistent

This needs a footnote/link, but I don't know where the proof is.

For instance, I'm having a hard time believing OWL full doesn't have a
FOL axiomatization....

This is just talking about outputting "Unknown" as mentioned two lines
down, right?  If so, then please drop this sentence from this
paragraph, where it is horribly confusing.

> Note: Complete OWL DL consistency checkers and Complete OWL Lite

How is a testing framework going to live with this?  I'd think they'd
need to return "ResourceLimitExceeded".

                      ^^^^^^^^^^  MUST NOT

I think you can remove that bit, now.

it's probably not necessary or appropriate.

But I love the test itself, and can't wait to try to pass it!


The test website itself needs some cleanup, but I guess that's a
different job.
