I feel like I'm using the editor's draft, but I'm not sure: http://www.w3.org/2001/sw/DataAccess/rq23/ Typos: "The following query has a solution: note that the query processor does not have to have any understanding of the values in the space of the datatype because, in this case, lexical form and dadatype URI both match exactly." s/dadatype/datatype/ though this made me laugh :) """2.2 Graph Patterns The building blocks of queries are triple patterns. Syntactically, a SPARQL triple pattern is a subject, predicate and object delimited by parentheses. The example in section 2.1 shows a triple pattern with a subject variable (the variable book), a predicate of dc:title and an object variable (the variable title). ( ?book dc:title ?title )""" (All the examples in 2.3 use parens) I think with turtle, triple patterns are no longer as stated? ""Reification vocabulary for the three predicates rdf:subject, rdf:predicate and rdf:object can be abbreviate using "<< >>"."" s/abbreviate/abbreviated/ ======== Quibbles: """ Other The keyword "a" can be used as a predicate in a triple pattern and is short for rdf:type.""" I would suggest removing this abbreviation. It's not all that helpful and takes us a bit further away from RDF/XML (though typed nodes might be stretched into analogues). Cheers, Bijan.
