OSID - osid.repository.AssetContentRepositoryAssignmentSession Service Interface Definition

Interface	osid.repository.AssetContentRepositoryAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.repository.RepositoryManager`
Used By	`osid.repository.RepositoryProxyManager`
Description	This session provides methods to re-assign `AssetContents` to `Repository` mappings. An `AssetContent` may appear in multiple `Repository` catalogs and removing the last reference to an `AssetContent` is the equivalent of deleting it. Each `Repository` may have its own authorizations governing who is allowed to operate on it. Adding a reference of an `AssetContent` to another `Repository is n` ot a copy operation (eg: does not change its `Id`).
Method	canAssignAssetContents
Description	Tests if this user can alter asset content/repository 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. T` his 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	canAssignAssetContentToRepository
Description	Tests if this user can alter asset content/repository 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.

Errors	NULL_ARGUMENT		`repositoryId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableRepositoryIds
Description	Gets a list of repositories including and under the given repository node in which any asset content can be assigned.
Parameters	`osid.id.Id`	`repositoryId`	the `Id` of the `Repository`
Return	`osid.id.IdList`		list of assignable repository `Ids`
Errors	NULL_ARGUMENT		`repositoryId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableRepositoryIdsForAssetContent
Description	Gets a list of repositories including and under the given repository node in which a specific asset content can be assigned.
Parameters	`osid.id.Id`	`repositoryId`	the `Id` of the `Repository`
Parameters	`osid.id.Id`	`assetContentId`	the `Id` of the `AssetContent`
Return	`osid.id.IdList`		list of assignable repository `Ids`
Errors	NULL_ARGUMENT		`repositoryId` or `assetContentId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignAssetContentToRepository
Description	Adds an existing `AssetContent` to a `Repository`.
Parameters	`osid.id.Id`	`assetContentId`	the `Id` of the `AssetContent`
Parameters	`osid.id.Id`	`repositoryId`	the `Id` of the `Repository`
Errors	ALREADY_EXISTS		`assetContentId` is already assigned to `repositoryId`
	NOT_FOUND		`assetContentId` or `repositoryId` not found
	NULL_ARGUMENT		`assetContentId` or `repositoryId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignAssetContentFromRepository
Description	Removes an `AssetContent` from a `Repository`.
Parameters	`osid.id.Id`	`assetContentId`	the `Id` of the `AssetContent`
Parameters	`osid.id.Id`	`repositoryId`	the `Id` of the `Repository`
Errors	NOT_FOUND		`assetContentId` or `repositoryId` not found or `assetContentId` not assigned to `repositoryId`
	NULL_ARGUMENT		`assetContentId` or `repositoryId` is `null`
	OPERATION_FAILED		unable to complete request

Compliance	`mandatory`		This method must be implemented.
Method	reassignAssetContentToRepository
Description	Moves an `AssetContent` from one `Repository` to another. Mappings to other `Repositories` are unaffected.
