Birte,

1/ A simple example involving the RDFS vocabulary subClassOf or subPropertyOf would be useful in showing the reader what is covered.

2/ Scoping Graph: it would be good to show the scoping graph in the discussion points.
 
3/ Boolean queries.

Doesn't the same applies to any BGP with no named variables, so { [] :p :o } has an empty domain for sigma.

4/ DESCRIBE: The result of BGP matching are combined using the algebra and finally the query form generates the results.  I wasn't clear why DESCRIBE might be different.
 
5/ What's the "signature of the scoping graph" - I did a google search and the top relevant hit was Design:EntailmentRegimes itself.  Most were about signing graphs from the named graphs paper.

6/ It would be useful to include RDF-entailment even if only to give it an IRI.

	Andy
