My view is that I planned to do the work that you described, but could
not justify the three or four months of my time that I thought it would
take without a DL toolset.

i.e. to build OWL DL rather than OWL Full costs more money, because you
have to ensure that you are in the DL subset, without enough DL tools to
justify this expenditure it is a waste of money and effort that could
better be spent elsewhere.

In as much as my decision to not do such work was made in collaboration
with my colleagues, manager and Jena users, this view represents a wider
opinion than just my own.

I, personally, also find the OWL DL story fairly compelling, but without
some substance behind it, from the DL community, cannot actually support
it with my own effort.
