Fixes a missing dependency

Shaper was not usable in release 2.7.2 due to a missing dependency. Patched in 2.7.2.1

Replaced parser for TURTLE and TURTLE_ITER

• TURTLE and TURTLE_ITER input formats will be kept for backwards compatibility, but they are both causing to parse the input as a stream using lightrdf parsers.
• Syntax errors when parsing turtle or nt files are now explicit.

RDF-Config including cardinalities

2.7.1

Ready for release 2.7.1

Machine-readable RDF annotations for any extra piece of information

Statistics, conformant examples, wikidata labels, and in general, every piece of information out of mere shapes and constraints, can be provided unsing RDF annotations (ShExC) or regular RDF (SHACL).

RDF annotations for property frequency usage

Incomplete feature! Don't mix these annotations with example nor wikidata annotations just yet

Bugfix with repeated names

Previous versions allowed the production of schemas with duplicate shape names. That's fixed with this release

Bugfix for RDF-Config generation and bugfix for SPARQL exploration

• RDF-Config: forcing lowercase for some names that the standard reject when containing capital letters.
• SPARQL: some endpoints retireve empty values for variables even when no OPTIONAL is specified, which raises errors. That has been fixed.

Release for first sync with Zenodo

2.6.3.0

Merge branch 'enhancement-#190'

Bugfix for RDF-Config generation and annotations

• Bugfix: double quotes are scaped when appearing inside a string, both in rdf-config and shex annotations.
• Bugfix: multiline annotations / examples in RDF-Config are tranformed into single line strings scaped newlines.
• Bugfix: RDF-Config generation was preventing ShEx/SHACL generation with some inputs. Now you can generate both in every case in a single execution.

Work on RDF-Config generation

• Improvement: variable names do not include numbers (except in extreme situations). More meaningful names are produced by using contextual information.
