RSPQL Query Isomorphism

This is a library to determine isomorphism relation between two RSPQL queries.

Coverage

Usage

Install the library using npm :

npm install rspql-query-isomorphism

Then, import the library in your code :

import { is_isomorphic } from 'rspql-query-isomorphism';

const query_one = `
    PREFIX : <https://rsp.js/>
    REGISTER RStream <output> AS
    SELECT (AVG(?v) as ?avgTemp)
    FROM NAMED WINDOW :w1 ON STREAM :stream1 [RANGE 10 STEP 2]
    WHERE{
        WINDOW :w1 { ?sensor :value ?v ; :measurement: ?m }
    }`;

const query_two = `
    PREFIX : <https://rsp.js/>
    REGISTER RStream <output> AS
    SELECT (AVG(?v) as ?avgTemp)
    FROM NAMED WINDOW :w1 ON STREAM :stream2 [RANGE 10 STEP 2]
    WHERE{
        WINDOW :w1 { ?sensor :value ?v ; :measurement: ?m }
    }`;

const result = is_isomorphic(query_one, query_two); // result = false
