rdf reasoner EyeClient

This is an EyeServer client with RDFJS specification Store interface (extends rdf-store-dataset).

You need an EyeServer instance running (available as a docker image).

usage

const ReasonerEyeClient = require('rdf-reasoner-eyeclient')
const reasoner = new ReasonerEyeClient({
    // all these options are default values
    url: 'http://localhost:8000', // EyeServer's url path (w/o '?' and the query)
    params: 'nope=true',          // parameters for EyeServer (separated by &)
    autoinfere: true,             // runs reasoner after every import of change
    data: [ 'http://eulersharp.sourceforge.net/2003/03swap/rpo-rules.n3' ],
                                  // RDF&OWL reasoning by default
    query: '{ ?a ?b ?c. } => { ?a ?b ?c. }.',
                                  // query all
    fetch: require('rdf-fetch')   // fetch implementation
})

Use reasoner.import(stream) to load data into the reasoner and use reasoner.match(subject, predicate, object) to get filtered stream of inferred data.

Data manipulation, adding and importing fires the reasoning process if autoinfere option is true (it's true by default).

Use reasoner.reason() to fire reasoning event on request.

You can access reasoner.inferred Dataset with sync interface if you don't want to get the dataset streamed by reasoner.match

This module contains an abstract class Reasoner which can be used to extend with another reasoner backend. It is enough to implement the reason() method taking data from this.dataset, inferring them and putting the result into this.inferred.

managing additional reasoning data

getData ()           // returns data array (does not fire autoinferring)
setData (data)       // sets the data array
addData (data)       // adds an element into the data array
removeData (data)    // removes an element from the data array
