Abstract: A data model versioning method may read a first version tag associated with a document database. The method compares the first version tag to a second version tag associated with a current document template of an application, the second version tag indicating a document format used by the current document template for documents created by the application. When the first version tag does not match the second version tag, the method performs a version migration operation to update a document format of documents in the document database.

Abstract: A first request is received, at a service application programming interface (API) of an authorization server, to change a permission of a first role for accessing a first resource. In response to the first request, a first role-based permission data structure associated with the first role is accessed to identify an entry associated with the first resource, where the first role-based permission data structure includes entries corresponding to resources, respectively. Each resource is associated with one or more permissions for a user of the first role to access the corresponding resource. One or more permissions are updated in the identified entry associated with the first resource.
