OSID - osid.offering.ParticipantAdminSession Service Interface Definition

Interface	osid.offering.ParticipantAdminSession
Implements	`osid.OsidSession`
Implemented By	`osid.offering.batch.ParticipantBatchAdminSession`
Used By	`osid.offering.OfferingManager`
Used By	`osid.offering.OfferingProxyManager`
Description	This session creates, updates, and deletes `Partiicpants`. The data for create and update is provided by the consumer via the form. `OsidForms` are requested for each create or update and may not be reused. Create and update operations differ in their usage. To create a `Participant`, a `ParticipantForm` is requested using `getParticipantFormForCreate()` specifying the offering, resource, and desired record `Types` or none if no record `Types` are needed. The returned `ParticipantForm` 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 `ParticipantForm` is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each `ParticipantForm` corresponds to an attempted transaction. For updates, `ParticipantForms` are requested to the `Participant` `Id` that is to be updated using `getParticipantFormForUpdate()`. Similarly, the `ParticipantForm` has metadata about the data that can be updated and it can perform validation before submitting the update. The `ParticipantForm` can only be used once for a successful update and cannot be reused. The delete operations delete `Participants`. To unmap a `Participant` from the current `Catalogue`, the `ParticipantCatalogueAssignmentSession` should be used. These delete operations attempt to remove the `Participant` itself thus removing it from all known `Catalogue` catalogs. This session includes an `Id` aliasing mechanism to assign an external `Id` to an internally assigned Id.

	`osid.id.Id`	`resourceId`	the resource `Id` for this participant
	`osid.type.Type[]`	`participantRecordTypes`	array of participant record types to be included in the create operation or an empty list if none
Return	`osid.offering.ParticipantForm`		the participant form
Errors	NOT_FOUND		`offeringId` or `resourceId` is not found
