Hello everyone! I have resources, users, and over 500 different relations. These relations change frequently (a couple of times a day). I want to make the relations a node so that it can be added via tupples, not by the schema. Can this be done?

Unfortunately that's not possible at this time for two reasons: 1) the schema compiler is making an optimization pass over the entire schema, and mapping duplicate relations to their canonical forms, and 2) the permission/relation input parameter when you do a permission check must refer to a known string in the schema that was uploaded and compiled

If I do like this: I will have actions with unique names, including for example the username. The resource will contain a link to this action, and from it the graph will be led to the user. Will it work? So correct?

have you seen the blog post on implementing Cloud IAM in spicedb?

Thanks! I'll try this.
