Parsing RDF

SRDF contains a trait to parse RDF data using combinators. The library follows a parser combinator approach where instead of parsing characters in sequence, we parse RDF nodes in a graph.

The design adapts the combine parser combinators library and tries to use a similar set of combinators for RDF parsing combinators.

Some of the combinators are:

• and: applies a parser followed by another one.
• and_then: applies a function to the result of a parser.
• ...

You can see more information and examples in RDFNodeParse trait.

This library has been used to implement the SHACL parser that reads RDF data as input and converts it to a SHACL abstract syntax tree.

One advantage of this approach is that rudof doesn't depend on any specific RDF format as it works directly with the RDF data model, which can in fact be obtained from RDf data in syntaxes like Turtle, RDF/XML, etc. or as a set of triples from an SPARQL endpoint.
