Hi Akash, I see the discussion in Issue 629. Can you submit a PR to add your work for Literals? That would be useful even before contributing to the SPARQL queries.
Regarding where to start with SPARQL, how about: https://github.com/RDFLib/rdflib/blob/master/rdflib/plugins/sparql/parser.py#L752 <https://github.com/RDFLib/rdflib/blob/master/rdflib/plugins/sparql/parser.py#L752> And then https://github.com/RDFLib/rdflib/blob/master/rdflib/plugins/sparql/operators.py#L720 <https://github.com/RDFLib/rdflib/blob/master/rdflib/plugins/sparql/operators.py#L720> The unary expression is detected, parsed and then evaluated at these points. The first point in the code does seem to be using Literal though... Feel free to add better stuff here other long-timer RDFlib contributors!
