             Summary: Turtle serializer: sort & align prefixes & "paragraphs"
                 Key: JENA-1262
                 URL: https://issues.apache.org/jira/browse/JENA-1262
             Project: Apache Jena
          Issue Type: Improvement
          Components: Cmd line tools
            Reporter: Vladimir Alexiev


1. Sort & align prefixes. Instead of this:

@prefix lcc-3166-1: <http://www.omg.org/spec/LCC/Countries/ISO3166-1-CountryCodes/> .
@prefix dct:   <http://purl.org/dc/terms/> .
@prefix owl:   <http://www.w3.org/2002/07/owl#> .
@prefix rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix lcc-3166-2: <http://www.omg.org/spec/LCC/Countries/ISO3166-2-SubdivisionCodes/> .
@prefix xsd:   <http://www.w3.org/2001/XMLSchema#> .
@prefix skos:  <http://www.w3.org/2004/02/skos/core#> .
@prefix sm:    <http://www.omg.org/techprocess/ab/SpecificationMetadata/> .
@prefix rdfs:  <http://www.w3.org/2000/01/rdf-schema#> .

@prefix lcc-cr: <http://www.omg.org/spec/LCC/Countries/CountryRepresentation/> .

it would be great to produce that:

2. "Paragraphs" 
(this applies only to non-streaming mode, i.e. --formatted=turtle).
By "paragraphs" I mean statements with the same subject, which RIOT separates by an empty line (i.e. that also matches the common definition of paragraph in text processing tools like Emacs).
If you sort them, in a well-constructed ontology that will output first the ontology, then Classes, the properties: which GREATLY aids understanding.
Eg see attached the FIBO BusinessRegistries ontology reformatted in this way.
