slide 13:
  Are these rules meant to be global, or local to ones' scope?
  What I mean to say is: I'd find it interesting to define such rules
  local to a context, or linking different RDF+Rules sources, i.e. to
  define views. However, this does not mean that these rules have global
  validity, such as rules in ontologies.

  This is an interesting aspect, since that would mean that rules are
  COMPLEMENTARY to ontologies rather than concurring.

  The semantics thant can (similar to SPARQL be defined on top of
  various possible entailment-regimes, starting from RDF simple
  entailment on the lower end to more complex entailment regimes taking
  e.g. RDFS semantics into account, etc.

slide 14:

  Where is the evaluation to take place?
  Imagine I publish such rules mixed with my foaf data on my web server:
   - Does the client who retrieves my foaf data see the rules or only (a
     finite subset of?) the materialized data.

slide 22:

  did you think about which EXISTING vocabularies/categorizations can be 
reused to describe the areas of expertise in CS or Music? These could be
relevant for us!

slide 25:

  Where is the information busy derived from? For instance, in our 
context, this could be done dynamically, by checking the rdf/ical export 
of peter's google-calendar, etc...
  We had btw a real demo exploiting such information in our ESWC 
tutorial on answer set programming rules on top of semantic web data, see
  http://asptut.gibbi.com/

slide 27:

a) What query language do you aim to use? SPARQL is a natural candidate!

b) Can the same rules also be expressed in e.g. N3, or is your approach 
in anyway depending on RuleML representation features possibly not 
available there? (I ask for the easier consumable surface syntax of N3, 
not knowing too much about the details of N3 rules so far to be honest...)


Looking forward to discussions!!!!

cheers,
axel
