Interfaceosid.ordering.ItemAdminSession
Implementsosid.OsidSession
Description

This session creates, updates, and deletes Items. 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 Item, an ItemForm is requested using geItemFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned ItemForm 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 ItemForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each ItemForm corresponds to an attempted transaction.

For updates, ItemForms are requested to the Item Id that is to be updated using getItemFormForUpdate(). Similarly, the ItemForm has metadata about the data that can be updated and it can perform validation before submitting the update. The ItemForm can only be used once for a successful update and cannot be reused.

The delete operations delete Items. To unmap an Item from the current Store, the ItemStoreAssignmentSession should be used. These delete operations attempt to remove the Item itself thus removing it from all known Store catalogs.

This session includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.
