Re: changes to document overview (done)

In this bit:

"OWL 2 QL enables conjunctive queries to be answered using standard
relational database technology; it is particularly suitable for
applications where relatively lightweight ontologies are used with
very large datasets, and where it is useful or necessary to access the
data directly via relational queries (e.g., SQL)."

my concerns would be that "very large datasets" could be misleading. I
don't know that QL has been used with more than a few million rows and
some people think of such as small. Also, I would put as coequal the
large data sets and the need to use relational database. Therefore I
would rephrase as:

"OWL 2 QL enables conjunctive queries to be answered using standard
relational database technology; it is particularly suitable for
applications where relatively lightweight ontologies are used to
organize relatively large numbers of individuals or where it is useful
or necessary to access the data directly via relational queries (e.g.,
SQL)."
