OSID - osid.repository.AssetContentAdminSession Service Interface Definition

Interface	osid.repository.AssetContentAdminSession
Implements	`osid.OsidSession`
Implemented By	`osid.repository.batch.AssetContentBatchAdminSession`
Used By	`osid.repository.RepositoryManager`
Used By	`osid.repository.RepositoryProxyManager`
Description	This session creates, updates, and deletes `AssetContents`. The data for create and update is provided by the consumer via the form object. `OsidForms` are requested for each create or update and may not be reused. Create and update operations differ in their usage. To create an `AssetContent`, an `AssetContentForm` is requested using `getAssetContentFormForCreate()` specifying the desired asset and record `Types` or none if no record `Types` are needed. The returned `AssetContentForm` will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the `AssetContentForm` is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each `AssetContentForm` corresponds to an attempted transaction. For updates, `AssetContentForms` are requested to the `AssetContent` `Id` that is to be updated using `getAssetContentFormForUpdate()`. Similarly, the `AssetContentForm` has metadata about the data that can be updated and it can perform validation before submitting the update. The `AssetContentForm` can only be used once for a successful update and cannot be reused. The delete operations delete `AssetContents`. To unmap an `AssetContent` from the current `Repository`, the `AssetContentRepositoryAssignmentSession` should be used. These delete operations attempt to remove the `AssetContent` itself thus removing it from all known `Repository` catalogs. This session includes an `Id` aliasing mechanism to assign an external `Id` to an internally assigned `Id`.
Method	getRepositoryId

Return	`osid.id.Id`		the `Repository Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getRepository
Description	Gets the `Repository` associated with this session.

Th` is is intended as a hint to an application that may opt not to offer create operations to an unauthorized user.
Return	`boolean`		`false` if `AssetContent` creation is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canCreateAssetContentWithRecordTypes
Description	Tests if this user can create a single `AssetContent` using the desired record types. While `RepositoryManager.getAssetContentRecordTypes()` can be used to examine which records are supported, this method tests which record(s) are required for creating a specific `AssetContent`. Providing an empty array tests if an `AssetContent` can be created with no records.
Parameters	`osid.type.Type[]`	`assetContentRecordTypes`	array of asset content record types
Return	`boolean`		`true` if `AssetContent` creation using the specified record `Types` is supported, `false` otherwise
Errors	NULL_ARGUMENT		`assetContentRecordTypes` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssetContentFormForCreate
Description	Gets the asset content form for creating new asset contents. A new form should be requested for each create transaction.
Parameters	`osid.id.Id`	`assetId`	an asset `Id`
Parameters	`osid.type.Type[]`	`assetContentRecordTypes`	array of asset content record types
Return	`osid.repository.AssetContentForm`		the asset content form
Errors	NOT_FOUND		`asetId` is not found
	NULL_ARGUMENT		`assetId` or `assetContentRecordTypes` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		unable to get form for requested record types
Compliance	`mandatory`		This method must be implemented.
Method	createAssetContent
Description	Creates a new `AssetContent`.
Parameters	`osid.repository.AssetContentForm`	`assetContentForm`	the form for this `AssetContent`
Return	`osid.repository.AssetContent`		the new `AssetContent`
Errors	ILLEGAL_STATE		`assetContentForm` already used in a create transaction
	INVALID_ARGUMENT		one or more of the form elements is invalid
	NULL_ARGUMENT		`assetContentForm` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		`assetContentForm` did not originate from `getAssetContentFormForCreate()`
Compliance	`mandatory`		This method must be implemented.
Method	canUpdateAssetContents
Description	Tests if this user can update `AssetContents`. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating an `AssetContent` will result in a `PERMISSION_DENIED. Th` is is intended as a hint to an application that may opt not to offer update operations to an unauthorized user.
Return	`boolean`		`false` if `AssetContent` modification is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	getAssetContentFormForUpdate
Description	Gets the asset content form for updating an existing asset content. A new asset content form should be requested for each update transaction.

	INVALID_ARGUMENT		the form contains an invalid value
	NULL_ARGUMENT		`assetContentForm` is `null`
	OPERATION_FAILED		unable to complete request

Compliance	`mandatory`		This method must be implemented.
Method	canDeleteAssetContents
Description	Tests if this user can delete `AssetContents`. A return of true does not guarantee successful authorization. A return of false indicates that it is known deleting an `AssetContent` will result in a `PERMISSION_DENIED.

A return of false indicates that it is known changing an alias will result in a `PERMISSION_DENIED`.This is intended as a hint to an application that may opt not to offer alias operations to an unauthorized user.

Compliance	`mandatory`		This method must be implemented.
Method	aliasAssetContent
Description	Adds an `Id` to an `AssetContent` for the purpose of creating compatibility. The primary `Id` of the `AssetContent` is determined by the provider.
