dereferencing subjectRefs in queries
(1:24:23 PM) Duane: what about a filter on relationships of a
particular type related to a digital subject with attribute xyz==fred
(1:25:17 PM) Jimse: that's a request for the filter to be able to
dereference stuff and continue applying parts of the filter upon the dereferences
thing
(1:25:25 PM) Jimse: Paul brought this up a few days back on the list
(1:25:30 PM) Jimse: I quickly ran away
(1:25:45 PM) Jimse: can this be done with SPARQL?

Do we want/need
the filter to allow one to cause references to other subjects to be dereferened
and have members of the dereferenced subject tested?
I know at least
the LDAP provider cannot do this (LDAP doesn't have the capability -- except in
one specialized case where the subject being tested is an alias). Does
SPARQL allow for this?
