We met similar problems when we tried to relate publications to neurons.

Check the research notes for CA3 pyramidal neuron:
http://senselab.med.yale.edu/senselab/NeuronDB/ndbEavSum.asp?id=259&mo=4&re=

All of the notes are about papers supporting the evidences of being
present or absent of a receptor/current/transmitter in a specific
compartment.  The notes can not simply attach to the neurocell class,
since they are actually annotations that should be attached to
statements.  All of the notes should be attached to the
owl:Restriction defined for those receptor/current/transmitter, see
the definition for CA3 pyramidal neuron in old DL syntax below.

If taking Alan's approach, we have to create additionally a huge
number of new named classes. For example, for CA3, we have to create
extra 30 named classes. And if take it as an average for other cells,
we have to create nearly 30*33=990 new named classes for all cells in
neuroDB. Previously we only have less than 50 classes in total.

We also have to come up new class name for each one which tends to be
long and somewhat odd. For example, the class name might be
AMPA_in_DAD_in_CA3_pyramidal_neuron.

Unnamed class is one of the elegant and neat features of DL,
especially in the cases where we do not want or do not know how to
explicitly specify the name.
Besides, I don't think unnamed class dis-enable the evidential
inference to take place.  For examples, the inconsistence we've just
found were inferred out from those unnamed class.

I've also found protégé does supports annotating unnamed classes, but
I'm not quite sure if the OWL specification allows us to do that?

Best all,
Huajun
