Difference between | and +?

[koudelka]

Is there an actual difference between the | and+ operators?

The + operator has documentation, but the | doesn't.

The schema playground seems to allow them to be used interchangeably.

[josephschorr]

| is for specifying different possible subject types on a relation and cannot be used as part of a permission: relation foo: firsttype | secondtype

+ is used for combining different relations within a permission and cannot be used on a relation: permission view = viewer + editor.

They are not interchangeable

Ah, you're totally right. I didn't see the little red syntax-error squiggle, color perception issues!
