public interface OntologyAdminSession
extends OsidSession

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

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

The delete operations delete Ontologies.

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

Method Detail

canCreateOntologies

boolean canCreateOntologies()

Tests if this user can create Ontologies. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating an Ontology will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer create operations to unauthorized users.

Returns:

false if Ontology creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateOntologyWithRecordTypes

boolean canCreateOntologyWithRecordTypes(Type[] ontologyRecordTypes)

Tests if this user can create a single Ontology using the desired record types. While OntologyManager.getOntologyRecordTypes() can be used to examine which records are supported, this method tests which record(s) are required for creating a specific Ontology. Providing an empty array tests if an Ontology can be created with no records.

Parameters:

ontologyRecordTypes - array of ontology record types

Returns:

true if Ontology creation using the specified Types is supported, false otherwise

Throws:

NullArgumentException - ontologyRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getOntologyFormForCreate

OntologyForm getOntologyFormForCreate(Type[] ontologyRecordTypes)
                                      throws OperationFailedException,
                                             PermissionDeniedException

Gets the ontology form for creating new ontologies. A new form should be requested for each create transaction.

Parameters:

ontologyRecordTypes - array of ontology record types

Returns:

the ontology form

Throws:

NullArgumentException - ontologyRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.

createOntology

OntologyForm createOntology(OntologyForm ontologyForm)
                            throws OperationFailedException,
                                   PermissionDeniedException

Creates a new Ontology.

Parameters:

ontologyForm - the form for this Ontology

Returns:

the new Ontology

Throws:

IllegalStateException - ontologyForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - ontologyForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - ontologyForm did not originate from getOntologyFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateOntologies

boolean canUpdateOntologies()

Tests if this user can update Ontologies. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating an Ontology will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer update operations to unauthorized users.

Returns:

false if Ontology modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getOntologyFormForUpdate

OntologyForm getOntologyFormForUpdate(Id ontologyId)
                                      throws NotFoundException,
                                             OperationFailedException,
                                             PermissionDeniedException

Gets the ontology form for updating an existing ontology. A new ontology form should be requested for each update transaction.

Parameters:

ontologyId - the Id of the Ontology

Returns:

the ontology form

Throws:

NotFoundException - ontologyId is not found

NullArgumentException - ontologyId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

updateOntology

void updateOntology(OntologyForm ontologyForm)
                    throws OperationFailedException,
                           PermissionDeniedException

Updates an existing ontology.

Parameters:

canDeleteOntologies

boolean canDeleteOntologies()

Tests if this user can delete ontologies. A return of true does not guarantee successful authorization.
