On LDOM

I think that LDOM is not the kind of thing that this working group is
supposed to be producing.  In LDOM you do not define shapes or constraints
and say how they relate to existing classes and properties.  Instead in LDOM
you define classes in a class hierarchy similar to the class hierarchy of
RDFS, but different.  In LDOM you define properties at classes and provide
local ranges and cardinalities for them, ignoring the domain and range
mechanisms from RDFS.  This makes LDOM a new modeling language, different
from RDF, from RDFS, and from every variant of OWL.  If there needs to be a
new W3C modeling language, then the work should be done by a group set up
for that purpose, not this group.
