why not just specify it as a schema then? are you constructing the schema from something else?

the schema is based on some external relationship.  as it changes, i would like to have a way to update schema, add in new definitions and relation between them or modify existing relations/definitions

sure, but the structure of the schema should change fairly rarely, compared to the relationships that form the data for your permissions

ok. is the recommendation to manually alter schema?

generally yes, unless you have a specific use case for generating it

if you're mutating schema often, then it usually indicates that you need a more data-driven schema, so you can change your permissions via relationships

relationship is a realization of a relation? These relations already exists in the schema.  thank so much!

yeah; a relationship fills in the data concretely for a `relation` defined in schema

heading offline for the evening, but please don't hesitate to ask any further questions; either I or someone will respond 🙂
