OSID - osid.workflow.WorkOfficeAssignmentSession Service Interface Definition

Interface	osid.workflow.WorkOfficeAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.workflow.WorkflowManager`
Used By	`osid.workflow.WorkflowProxyManager`
Description	This session provides methods to re-assign `Works` to `Office` mappings. A `Work` may appear in multiple `Offices` and removing the last reference to a `Work` is the equivalent of deleting it. Each `Office` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `Work` to another `Office` is not a copy operation (eg: does not change its `Id`).
Method	canAssignWorks
Description	Tests if this user can alter work/office mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping methods in this session will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignWorksToOffice
