Where should I define global variables shared across collections?

I have a suite of microservices. Each service is a collection. My APIs share some core (JSON) objects. I’d like to define the schema for those shared objects once and re-use it across all my tests:

pm.test('response has correct schema', function () {
    const {data} = pm.response.json();
    if (!tv4.validate(data, pm.globals.get('shared_object_schema')
)) {
        console.error(tv4.error);
        pm.expect.fail()
    }
});

(Actually I’d like to reuse the tests across the collections as well, but that’s another issue.)

Where is the best place to define pm.globals.set('shared_object_schema', ...) so that it’s available in every endpoint across my entire workspace?
