Allow "cross store" relations

[LaserPhaser]

I would like to request something like “cross-store/model” relations
For example, I have a model that describes access to the GitLab
And I have a separate model that describe access to the k8s
and everything goes well,
after a while I can probably decide to allow access to k8s namespaces according to GitLab groups because they are similar
To do it now, I must merge both models and rename identical types from both.
What I request is to use store/model name/uuid as “prefix” to be able somehting lie

# GITLAB Store
type user

type organization
  relations
    define member: [user]
    define admin: [user]

type group
  relations
    define member: [user]
#K8S store
type user

type organization
  relations
    define member: [user, GITLAB.user:*] # here is the link to the other model
    define admin: [user]

type group
  relations
    define member: [user]

So basically I can keep models separate and not merge them
And I would be able to have common types in different models

Hey @LaserPhaser!

We're unlikely to support cross-store requests, as the store concept is meant to be a hard boundary between entities.

For your needs, may I suggest Modular Models?

If, later on, you want to give different write access based on the module of a tuple, we also have experimental access control which builds on top of Modular Models and allows you to restrict Write access based on the module of a tuple.
