David, well spoken. There is also the cost issue - in the real world,
sterile test tubes cost money, and the high rate of volume we are expecting
makes it add up to real money. The exact point in the work flow at which
those identities are made unique is far more complex than just the
scientific issues at hand. Labor optimization to feed the tubes in, and
take the product and waste out, is also a cost-sensitive issue in work flow
design. That impacts when the individual tubes are identified uniquely. (01)
So the EVENT at which the tubes become identified, or named, or keyed, has
work flow and cost issues that will be at least as complicated as the
scientific issues. The scientific view will be only a projection of data
from the real ontology; so will the cost views. They have to be calculated
from the same real world database. (02)
Expect real world databases to have all kinds of other complexities too. So
the design criteria for a scientific ontology ought to be based on a wide
variety of use cases, though the scientific view of the database can be
extracted from that real world database. But don't count on pushing the
data in the opposite direction without considering all those "extraneous"
conditions that will arise; they will impact the scientific view in
unexpected ways. (03)
Choice of binding time (identifying, naming, whatever term you choose)
significantly affects database processes, depends on the economics of the
plant, and has to be understood as a use case class. (04)
I think the best way to handle it is to define binding events capable of
supporting the various binding times. When the box/case/assembly comes into
receiving, it should be bound to an identifier. When the box/.. is opened
and made available for withdrawing partial lots, a new event definition is
needed in the ontology. When each partial lot is extracted, still another
kind of event should be defined in the ontology. (05)

Maybe... depends on the level of identification (not necessarily the
same as naming) needed for the task the test tubes are being used for. (010)
I had a conversation once with someone about "rare earths" (not that
I really know what they are). Their database needed to track back to
which mine a rare earth came from... seems that rare earths from Mine
A used in a manufacturing process didn't work so well, while those
from Mine B did. After thousands of manufacturing steps failure was
determined by some trace element from a particular site on the earth
vs another. (011)
I could certainly foresee the potential for individually identifying
(tube #12 from box #123-45-6789) every tube... say if you're doing
some super sensitive test in the tube. At some point it might be
necessary to track back to the box, the manufacturer & the
manufacturing batch. (012)
I would certainly want to have more information about the needs for
identifying vs naming. Do we just need to keep track of the 10,000
test tubes? Or do we want to be able to see-or not-that John Smith's
blood is in this tube? (013)
Or is identification & naming assumed to be the same thing? (014)
