Pat, Barry, Deborah, and Ed,    (01)

Barry asked an important question that gets to the heart of
the issues we have been discussing:    (02)

BS> What are scientific journals for?  Why do they employ a peer
 > review process?    (03)

There are two independent issues here:  reviewing and publishing.
Everybody would agree that reviewing is important, but ideally,
the readers/users should have the option of making their own
choices based on the reviews.  When publication was expensive,
the publishers became gatekeepers because it was economically
impractical to publish everything.    (04)

But with the WWW, new options are available.  Publication is
almost free, and we have the luxury of decoupling the reviewing
process from the gatekeeping process.  Metadata enables that
decoupling:    (05)

  1. All submissions to the OOR can be made available as soon
     as they are submitted.    (06)

  2. The metadata associated with each submission can indicate
     what tests were made, what the reviewers said, and what
     results the users, if any, obtained.    (07)

  3. Users can choose to see ontologies sorted by any criteria
     they want:  in the order of best reviews, most thorough
     testing, greatest usage, greatest relevance to a particular
     domain, or any weighted combination.    (08)

Ontologies overlap philosophy, engineering, science, and mathematics.
The closest model we have is the metadata registry, but new policies
can and should be explored.    (010)

That is the point I was trying to emphasize.  The application
developers have deeper understanding of their specific needs and
problems than any general gatekeeper or committee of gatekeepers.    (013)

DM> CSI, the specification writing organization for building
 > architecture, says quality is "a mirror of the requirements."    (014)

That's a good point, which implies that different set of
requirements might lead to a different ranking of the same
ontologies.   No gatekeeper can anticipate the requirements
of all possible users.    (015)

DM> Do you think the gatekeepers can help define the OOR requirements

I'd prefer to keep the reviewers and replace the gatekeepers with
caretakers who have a broader role along the lines you suggested.    (017)

That suggests a further refinement of the roles of reviewers and
gatekeepers/caretakers.  At the source, there are individuals and/or
organizations, who develop ontologies and make them available.
Among the users, there may be organizations, coalitions, or
bureaucracies that evaluate the ontologies and determine which
of them are best suited to their groups of users.    (019)

That is another reason for replacing the gatekeepers in the OOR
with caretakers.  Any gatekeeping that might be useful would be
better done by user groups at a level close to the applications
than by any gatekeeper that is close to the ontology providers.    (020)
