This reply concerns the status of my proof giving between the triples and the mapping rules. herman.ter.horst@philips.com wrote: > I did not review Section 4.3 as it appears in Jeremy's recent > mail to Webont [1].

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.
