SPARQL/Query 1.0

Outstanding

Use of bold in "Definition: ..." is still inconsistent.

Section 12.4: Better would be (adds "for all") 

set-union
   { μ1 | μ1 in Ω1, for all μ2 in Ω2, μ1 and μ2 are compatible and expr(merge(μ1, μ2)) is false }

Wording / Typos

(done)

  • In the table of contents, s/Restricting the Value/Restricting the Values/ to match the actual section name (ref)

(done)

  • In the change log, s/14 June 2007 Candidate Recommendation/12 November 2007 Proposed Recommendation/. (ref)

[52] AdditiveExpression ::= MultiplicativeExpression 
                           ( '+' MultiplicativeExpression | 
                             '-' MultiplicativeExpression |

                            )*

(fixed in grammar - wil be correct when SPARQL 1.1 Grammar is finialized)

(done - unique might imply a semantic relationship - it's just the distinctness of terms that can be done here)

  • Below the definition of LeftJoin, the text that says "{ μ1 | μ1 in Ω1and μ2 in Ω2, and μ1 and μ2 are not compatible }" is not clear in the case where Ω2 is empty. (ref)

(Added text to clarify "or Ω2 is empty")

  • In the example in 10.3 ASK the boolean element should be a direct child of the sparql element; the results element should be removed. (ref)

SPARQL/Protocol 1.0

  • In 2.2.1.5 DESCRIBE with simple RDF dataset, the opening rdf:RDF tag should be closed with a right angle bracket. (ref)
  • Throughout, right-angle brackets should be coded in the HTML as an entity > (ref)
  • In section 2, check usage of 'comprises'. (ref)
  • In 2.2, s/under constrained/under-constrained. (ref)
  • (Presentation). Request to not have individual horizontal scroll bars on PRE elements. (ref)

SPARQL XML Results 

http://www.w3.org/2007/SPARQL/result.rng
http://www.w3.org/2007/SPARQL/result.rnc
http://www.w3.org/2007/SPARQL/result.xsd

includes the optional "index" attribute but that didn't make the final design and was dropped. It isn't in the W3C REC doc at http://www.w3.org/TR/rdf-sparql-XMLres/ 

"The SPARQL Query Language for RDF [SPARQL-QUERY] defines several 
 Query Result Forms (SPARQL Query section 10). This document 
 defines a SPARQL Results Document that encodes the variable 
 binding query results from SELECT queries (SPARQL Query 
 section 10.2) and boolean query results from ASK queries 
 (SPARQL Query section 10.5)"

but the section numbering is wrong: "SELECT" is 10.1 and "ASK" is 10.3.
