The slot_roles table is a normalization table for role names. It is used by the slots table.
In PHP code, normalization is managed via NameTableStore.
It was introduced in MediaWiki 1.31 as part of the Multi-Content Revisions project; see Multi-Content Revisions/Content Meta-Data for details. During migration from older versions, the table is populated by populateContentTables.php (run automatically by the upgrade script).
Fields
role_id
Primary key.
role_name
Description of the name of the role.
