Queries on a 3D-model

BOT and reasoning

Hylar is a simple js library for doing reasoning on a set of triples. To get it up and running, do the following:

1) Initialize a new project with npm init 2) Add Hylar as dependency npm install --save hylar (first you need node and node-gyp: https://github.com/nodejs/node-gyp) 3) Adjust the following code sample to your needs and try it out

var Hylar = require('hylar');
var fs = require('fs');
h = new Hylar();

//Files and settings
var mimeType = 'text/turtle';
var files = [];
files.push('triples.ttl');
files.push('bot.ttl');

var query = "PREFIX bot: <https://w3id.org/bot#>\
SELECT * WHERE {?subject a bot:Zone}";

//Get file content
triples = '';
for(var i in files){
    var string = fs.readFileSync(files[i], "utf8").toString();
    if(i == 0){
        triples = string;
    }else{
        triples+='\n'+string;
    }
}

//Do reasoning and run query
h.load(triples, mimeType)
    .then(response => {
        return h.query(query);
    })
    .then(results => {
        console.log(results) // log results to console
    });
