This session creates, updates, and deletes Scenes in bulk. 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 a Scene, a SceneForm is requested using getSceneFormsForCreate() specifying the desired record Types or none if no record Types are needed. Each of the returned SceneForms 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 a SceneForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each SceneForm corresponds to an attempted transaction.

The SceneForms returned from getSceneFormsForCreate() may be linked to the originating request through the peer Ids of the SceneForm. In the case where there may be duplicates, any SceneForm of the same peer Ids may be used for a create operation.

Once a batch of SceneForm are submitted for create, a CreateScene is returned for each SceneForm, although the ordering is not defined. Only errors that pertain to the entire create operation are returned from createScenes(), errors specific to an individual SceneForm are indicated in the corresponding CreateScene. CreateScenes may be linked to the originating SceneForm through the SceneForm Id .

For updates, SceneForms are requested to the Scene Id that is to be updated using getSceneFormsForUpdate() where the reference Id in the SceneForm may be used to link the request. Similarly, the SceneForm has metadata about the data that can be updated and it can perform validation before submitting the update. The SceneForm can only be used once for a successful update and cannot be reused.

Once a batch of SceneForms are submitted for update, an UpdateScene is returned for each SceneForm, although the ordering is not defined. Only errors that pertain to the entire update operation are returned from updateScenes(), errors specific to an individual SceneForm are indicated in the corresponding UpdateScene. UpdateScenes may be linked to the originating SceneForm through the SceneForm Id.

The delete operations delete Scenes in bulk. To unmap a Scene from the current System, the SceneSystemAssignmentSession should be used. These delete operations attempt to remove the Scene itself thus removing it from all known System catalogs. Bulk delete operations return the results in DeleteScenes.
