Hm. Not directly. There is a mailing list:

DC-ARCHITECTURE@JISCMAIL.AC.UK

to which you could sign up, I suppose, but I am not sure you want
that... There is probably an archive somewhere... But I was not involved
in the discussions around those 'surrogate'-s, so I really cannot say.

However. While I do not want to defend their modelling practice, we have
to acknowledge that they are there, they exist, and they represent a
major community (through the DCMI we get to the whole library community
which is not a small one) that we may want to serve by providing punning
of datatype/object properties. That is all...
