Boris, Bernardo,


Some minor (and editorial) comments:

1. In the intro on DL-Lite, you say:

"it is, therefore, a proper super-set of the RDFS fragment of OWL 1.1 DL."

I have two problems with this

- this document may become, eventually, the official W3C document, we 
should not have a reference to any 'other' OWL1.1, as those will not 
become part of a recommendation (maybe a note).

- even if we decide to use the original submission for, eg, a note, I 
would personally prefer not to use the name 'RDFS' for that fragment. 
The acronym RDFS is used for RDF Schemas as defined in the 2004 
recommendation; it is a misnomer to use it for a fragment (I did not 
care about it for the submission, but it becomes another matter if part 
of an official W3C document produced by this group...

2. In the spec of EL++ and DL-Lite 'facts' is listed as features 
provided by EL++. Eg, I can use SameIndividual or, in RDF speak:-) 
owl:sameAs. This is not present in the OWL-R DL spec; actually, there is 
no (handy) list of feature overview. It took me a certain time (and 
looking at the OWL-R Full version) to find the owl:sameAs is indeed 
usable (and this is probably by far the most widely used owl term used 
out there these days...).

I guess this is really editorial: the description of OWL-R DL should 
follow the same pattern as the other two...

3. In the fragment complexity table you refer to OWL DL in the top row. 
Is that OWL1.1 DL or the 'old' DL? I am a bit confused with all the
