If you prefer [Extended Backus-Naur Form (EBNF)](https://www.w3.org/TR/REC-xml/#sec-notation) notation, you can also see [N3 grammar in EBNF](https://github.com/lszeremeta/n3/blob/master/other-notations/N3.ebnf).\n\n[Notation 3 (also known as N3)](https://www.w3.org/TeamSubmission/n3/) is an assertion and logic language which is a superset of RDF. N3 extends the RDF datamodel by adding formulae (literals which are graphs themselves), variables, logical implication, and functional predicates, as well as providing an textual syntax alternative to RDF/XML.\n\nThis project based on [ANTLR grammars-v4 project](https://github.com/antlr/grammars-v4).\n\n## Testing grammar\n\nRun tests on files in ``n3/examples``:\n\n```shell\nmvn clean test\n```\n\n## Contribution\n\nWould you like to improve this project?
