Conclusion:

The content of the document is basically ready to go.  Good work, it is 
short and concise and, i believe, achieves its stated goal.  The document 
is not ready for publication, however, as a lot of links are missing and 
there are still indications of work to be done.

Corrections & Suggestions:

In abstract, change:
"OWL facilitates greater machine readability of web content than that 
supported by XML, RDF, and RDF Schema by providing additional vocabulary." 
->
"OWL facilitates greater machine readability of web content than that 
supported by XML, RDF, and RDF Schema by providing additional vocabulary 
along with a formal semantics."

In 1.0, change:
"OWL is intended to be used by applications that need to process the 
content of information, instead of presenting just human-readable content. 
OWL can be used to explicitly represent term vocabularies and the 
relationships between entities in these vocabularies. This representation 
of terms and their interrelationships creates an ontology. The ontology 
language in OWL is more expressive than that in XML, RDF, and RDF-S, and 
thus OWL goes beyond these language in its ability to represent machine 
readable content on the web." ->
"OWL is intended to be used by applications that need to process the 
document content, as opposed to presenting the content to humans. OWL can 
be used to explicitly represent the meaning of terms in vocabularies and 
the relationships between those terms. This representation of terms and 
their interrelationships is considered an ontology. OWL has more 
facilities for expressing meaning and semantics than XML, RDF, and RDF-S, 
and thus OWL goes beyond these language in its ability to represent 
machine readable content on the web."

"A glossary of the terminology used in this and the other documents can be 
found in the OWL Guide." ->
The URL for the glossary is #OWLGlossary

Section 1.2 is simply awesome.

In section 2.0:
"In this document, italicized terms are terms in OWL. Prefixes of rdf: or 
rdfs: are used when terms are already present in RDF or RDF Schema. 
Otherwise terms are introduced by OWL. Thus, the term Class is more 
precisely stated as owl:Class and rdfs:subPropertyOf indicates that 
subProperty is already in the rdfs vocabulary (technically: the rdfs 
namespace). " ->
This is poorly stated. Explain what you mean with owl:class a little 
better.

2.1&2.2: The table is very nice. As noted in the text, all the links have 
to be filled in.
