Converts a JSON Schema to a SimpleSchema in meteor

first I have rdf file was converted to Json file by ( then I used (shamblen:json-simple-schema) package to Converts a JSON Schema to a SimpleSchema but it made error

C:\Users\ISLAM\AppData\Local.meteor\packages\meteor-tool\1.4.4_1\\dev_bundle\server-lib\node_modules\fibers\future.js:280 throw(ex); ^

Waiting for file change.

Could help me? does (shamblen:json-simple-schema) package the most appropriate to deal with Json schema?

The error is due to a missing reference to $ in imports/api/lib/collection.js. Assuming that $ refers to jquery, adding an explicit import to the affected file should fix the problem: import { $ } from 'meteor/jquery';
