OSID - osid.resourcing.CompetencyLookupSession Service Interface Definition

Interface	osid.resourcing.CompetencyLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving premade `Competencies.` The `Competency` represents a set of efforts `.` This session defines views that offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete set or is an error condition isolated foundry view: All competency methods in this session operate, retrieve and pertain to competencies defined explicitly in the current foundry. Using an isolated view is useful for managing `Competencies` with the `CompetencyAdminSession.` federated foundry view: All competency methods in this session operate, retrieve and pertain to all competencies defined in this foundry and any other competencies implicitly available in this foundry through foundry inheritence. Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods `useFederatedFoundryView()` and `useIsolatedFoundryView()` behave as a radio group and one should be selected before invoking the methods in this session.
Method	getFoundryId
Description	Gets the `Foundry` `Id` associated with this session.
Return	`osid.id.Id`		the `Foundry Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getFoundry
Description	Gets the `Foundry` associated with this session.
Return	`osid.resourcing.Foundry`		the foundry
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupCompetencies
Description	Tests if this user can perform `Competency` lookups. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer lookup operations to unauthorized users.
Return	`boolean`		`false` if lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeCompetencyView
Description	The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
Compliance	`mandatory`		This method is must be implemented.
Method	usePlenaryCompetencyView
Description	A complete view of the `Competency` returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.
Compliance	`mandatory`		This method is must be implemented.
Method	useFederatedFoundryView
Description	Federates the view for methods in this session. A federated view will include competencies in foundries which are children of this foundry in the foundry hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedFoundryView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this foundry only.
Compliance	`mandatory`		This method is must be implemented.
Method	getCompetency
Description	Gets the `Competency` specified by its `Id.` In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `Competency` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `Competency` and retained for compatibility.
Parameters	`osid.id.Id`	`competencyId`	`Id` of the `Competency`
Return	`osid.resourcing.Competency`		the competency
Errors	NOT_FOUND		`competencyId` not found
	NULL_ARGUMENT		`competencyId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method is must be implemented.
Method	getCompetenciesByIds
Description	Gets a `CompetencyList` corresponding to the given `IdList.` In plenary mode, the returned list contains all of the competencies specified in the `Id` list, in the order of the list, including duplicates, or an error results if an `Id` in the supplied list is not found or inaccessible. Otherwise, inaccessible `Competencies` may be omitted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`competencyIds`	the list of `Ids` to retrieve
Return	`osid.resourcing.CompetencyList`		the returned `Competency` list
Errors	NOT_FOUND		an `Id` was not found
	NULL_ARGUMENT		`competencyIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getCompetenciesByGenusType
Description	Gets a `CompetencyList` corresponding to the given competency genus `Type` which does not include competencies of genus types derived from the specified `Type.` In plenary mode, the returned list contains all known competencies or an error results. Otherwise, the returned list may contain only those competencies that are accessible through this session.
Parameters	`osid.type.Type`	`competencyGenusType`	a competency genus type
Return	`osid.resourcing.CompetencyList`		the returned `Competency` list
Errors	NULL_ARGUMENT		`competencyGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getCompetenciesByParentGenusType
Description	Gets a `CompetencyList` corresponding to the given competency genus `Type` and include any additional competencies with genus types derived from the specified `Type.` In plenary mode, the returned list contains all known competencies or an error results. Otherwise, the returned list may contain only those competencies that are accessible through this session.
Parameters	`osid.type.Type`	`competencyGenusType`	a competency genus type
Return	`osid.resourcing.CompetencyList`		the returned `Competency` list
Errors	NULL_ARGUMENT		`competencyGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getCompetenciesByRecordType
Description	Gets a `CompetencyList` containing the given competency record `Type.` In plenary mode, the returned list contains all known competencies or an error results. Otherwise, the returned list may contain only those competencies that are accessible through this session.
Parameters	`osid.type.Type`	`competencyRecordType`	a competency record type
Return	`osid.resourcing.CompetencyList`		the returned `Competency` list
Errors	NULL_ARGUMENT		`competencyRecordType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getCompetencies
Description	Gets all `Competencies.` In plenary mode, the returned list contains all known competencies or an error results. Otherwise, the returned list may contain only those competencies that are accessible through this session.
Return	`osid.resourcing.CompetencyList`		a list of `Competencies`
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
