This reply concerns the status of my proof giving between the triples and 
the mapping rules.

Short answer:
The proof needs work that I can do within, but not before, the last call 
period.


Long answer:


The last version of the proof that I worked on is in the CVS history of

http://www.w3.org/2001/sw/WebOnt/syntaxTF/prolog/out/dl/proof1.html

I will dig it out and put it back as the current version.

However, it suffers from:

+  i's not dotted and t's not crossed
   I suspect there is another couple of days work on that front.
+  the syntax it is based on is not identical to Peter's.
   The differences are now entirely stylistic:
    the two priciple ones being
     + use of classID(uriref) instead of classID etc.
     + use of one ontology with multiple headers instead of multiple ontologies
+ there are also some unnecessary (and unimportant) differences that need 
to be removed.

Of these I might be able to correct the former in the output routines, or 
alternatively provide a introductory gloss explaining it away - however my 
code will not work without it.

The latter could also possibly be corrected - but it is somewhat ugly; an 
introductory gloss explaining it away might be more elegant.

The advantage of not needing either introductory gloss is that I would not 
need to duplicate the grammar - however it is convenient/necessary to have 
each grammar rule and mapping rule numbered and with an anchor.
