Hi, Please find my review below. Thanks, Matt ------------------------------------------------------ Section 8.1: Question: is NOT EXISTS { ... } equivalent to !EXISTS { ... } ? Section 8.2: In the first paragraph would it be better to use "left-hand side" and "right-hand side" instead of "one side" and "other side" ? Typos: "evaluates both [it's] arguments" => [its] Section 9 introduction: "any given path expression" at the end of the second paragraph should be removed. "Cycles in the graph and in paths are possible" -- from the definition of arbitrary length path, it looks like cycles are not possible in aribtrary length paths. Is it only fixed-length paths that may contain cycles? Section 9.2: Typos: "Example: Find nodes connected but not by [rdf;type]" => [rdf:type] "Note: This path expression does not [gaurantee] the order of the results" => [guarantee] Section 9.3.5: Does the term "intermediate node" used in the definition of ArbitraryLengthPath need to be formally defined? Typo: "intermediate nodes in the graph are [trarversed] once only." => [traversed] Section 9.3.6.2: Typo: "and [deteching] when a graph node" => [detecting] Section 10.2 Introduction: Defintion: Aggregation In the definition of Aggregation, the purpose of card[range(g)] - card[M] was not clear to me until after I read Section 10.2.2. There should be an explanation of the purpose of this argument to accompany the defintion of Aggregation. Typo: In the example at the end of this section involving ex:agg, parenthesis are mismatched and eg:agg should be changed to ex:agg. Section 15.1.2: Typo: "Variables can [be] also be used in expressions if they are introduced [as to the] earlier, syntactically in the same SELECT clause:" => remove the identified text Section 16.4.14: COALESCE(5,?x) returns 2 ... shouldn't this return 5? Section 16.4.15: Typo: "interprets it as a effective boolean value, [the]" => [then] Section 16.4.16: I don't understand this sentence: "Errors in comparisons cause the IN expression to raise an error if the RDF term being tested is not found to be in the list elsewhere in the list of terms" I understood the sentence after looking at the examples but not after reading it. I think it would be clearer if "to be in the list" was removed. Section 16.4.21: should "str"^^<http://example/romanNumeral> be "iiii"^^<http://example/romanNumeral> ? Section 16.4.22: Should "123"@en be "chat"@en ? SPARQL 1.1 Federation Extensions: Abstract: Typo: "Query extension [to] for executing distributed queries" => remove "to" Section 2, 3rd from last paragraph: Typo: "SPARQL [Alebra]" => [Algebra] End of Section 2.1 (editorial note): Typo: "as [it] the question of having variables in ..." => [is] Example in Section 3: variable ?iuphar is undefined Typo (2nd to last paragraph in Section 5.1): "It is a syntax error [if] to use..." => remove if
