MOP comes from lisp (I think), not NeoCore.  NeoCore is just a
self-constructing XML database, but it supports XPATH and XQuery and
(obviously) InfoSets.

This is my dissertation topic, but MOP has been around a while.  Most of the
stuff I am reading comes off either IEEE or ACM.

For a quick overview, here are some links:
http://iamwww.unibe.ch/~demeyer/Deme96m/psstmnt.html
http://c2.com/cgi/wiki?MetaObjectProtocol
http://www.elwoodcorp.com/alu/mop/contents.html

Although this originally comes from LISP, which is a self-modifying
language, it was my intent to implement using the Reflection capabilities of
Java or C#.

The actual dissertation revolves around the *rules* to creating the XML
Information Model.

This is interesting. Where can we find out more about MOP? Is it
specific to the NeoCore XMS? I didn't find any reference to it on their
site.

Thanks,
