Minor comments

Hi,
I’ve been going through this nice document [1]. 
First, I’d like to congratulate you for this work that has many applications in RDF data validation. 

Find below some minor typos

+ In "STRING FACETS EXAMPLE 1" sample, the report uses "ex:submittedOn" instead of "ex:submittedBy" 

== minor typos in the document ==  
+ JSON[rfc4627] --> JSON [rfc4627]
+ semantics[rdf11-mt] --> semantics [rdf11-mt]
