This is a JavaScript library offering a wrapper around the Java RMLMapper.
- Node.js
- Java VM
- Jar of the RMLMapper,
which you can download via
npm run download:rmlmapper.
const RMLMapperWrapper = require('@rmlio/rmlmapper-java-wrapper');
const fs = require('fs');
const rmlmapperPath = './rmlmapper.jar';
const tempFolderPath = './tmp';
const wrapper = new RMLMapperWrapper(rmlmapperPath, tempFolderPath, true);
const rml = fs.readFileSync('./test/tc01/mapping.ttl', 'utf-8');
const sources = {
'student.csv': fs.readFileSync('./test/tc01/student.csv', 'utf-8')
};
const result = await wrapper.execute(rml, {sources, generateMetadata: false, serialization: 'turtle'});Note that you can also provide an array of quads to execute instead of a string with RDF.
An example can be found in the tests.
