YARRRML Parser

This library allows to convert YARRRML rules to RML or R2RML rules.

Install

• npm i -g @rmlio/yarrrml-parser

Usage

CLI

There are two CLI functions, yarrrml-parser and yarrrml-generator. Using the --help flag will show all possible commands.

yarrrml-parser

If you want to generate RML rules from a YARRRML document, you do the following: yarrrml-parser -i rules.yml. The rules will be written to standard output. If you want to write them to a file, you can add the -o option. By default RML rules are generated, if you want to generate R2RML rules add -f R2RML.

yarrrml-generator

If you want to generate YARRRML rules from an RML document, you do the following: yarrrml-generator -i rules.rml.ttl. The rules will be written to standard output. If you want to write them to a file, you can add the -o option.

Library

npm i --save @rmlio/yarrrml-parser

let yarrrml = require('@rmlio/yarrrml-parser/lib/rml-generator');

const yaml = "[yarrrml string]";
const y2r = new yarrrml();
const triples = y2r.convert(yaml);
