The CheckOut operation signifies to a CSDB Management System that a learning content authoring tool or application would like to reserve a CSDB object. The CheckOut operation requires the CSDB Management System to perform appropriate CSDB Management System specific checkout procedures. Minimally, the CSDB Object is required to be locked (or reserved) and not permitted to be edited by any other user or entity until the CSDB Object’s lock is released. By checking out the CSDB Object, a private working copy of the object is created for the client application that made the service call.
The S1StructuredIdentifier can be used in several ways during a CheckOut operation:
-
If the client would like the latest version of the CSDB Object, the client application should not include any of the following issue information: inWork, issueNumber. When these values are left out of the S1StructureIdentifier, the CSDB Management System is required to return the latest version of that CSDBObject.
-
If the client provides the inWork and issueNumber, then the CSDB Management System has two options:
-
Check out and return the specific identified CSDB Object. This implies that the CSDB Management System supports some form of branching/merging feature to align the changed file (e.g., specifically if the identified CSDB Object is not the current version). NOTE: A branching/merging feature is not required to be supported by this specification.
-
Determine if the inWork and issueNumber provided represents the latest version. If so, then the CSDB Object can be returned. If the inWork and issueNumber does not identify the latest version, then the CSDB Management System can issue an appropriate fault (INVALID_STRUCTURED_IDENTIFIER) to indicate the error along with a description of the error.
Input Parameters:
-
S1StructuredIdentifier (S1StructuredIdentifier_Type): The S1000D structured identifier that represents the CSDB Object to check out. The S1StructuredIdentifer shall be represented as valid S1000D URN syntax (e.g., URN:S1000D:DMC-S1000D-A-07-05-0000-00A-000A-A_I-001_W-00_L-SX_C-US.
-
SessionID (xs:string): The session identifier for the connected end user.
Output Parameters:
-
CSDBObject (Attachment_Type): This parameter represents the CSDB Object that is being checked out.
Error Conditions:
-
INVALID_STRUCTURED_IDENTIFIER
-
INVALID_SESSION_IDENTIFIER
-
SESSION_NOT_ACTIVE
-
OPERATION_NOT_PERMITTED
-
CSDB_OBJECT_ALREADY_CHECKED_OUT
-
CHECKED_OUT_OBJECT_LIMIT_REACHED
UndoCheckOut
The UndoCheckOut operation enables an authoring tool or application to reverses the effect of a CheckOut operation call and remove the private working copy of the checked-out CSDB Object. During the processing of an UndoCheckOut, the CSDB Management System should ignore any changes that may have been made to the CSDB Object. This also requires the CSDB Management System to not adjust the inWork number. Since the UndoCheckOut operation was called, the authoring tool or application has stated its intent to ignore all work that was done; therefore, there is no need to create a new in work version.
This operation can only be performed by a user who has the rights to perform the operation:
NOTE: Because an UndoCheckOut can be performed across sessions, the CSDB Management System must design a way to track who has checked out what CDSBObjects. How this is implemented is outside the scope of this specification.
Input Parameters:
-
S1StructuredIdentifier (S1StructuredIdentifier_Type): The S1000D structured identifier that represents the CSDB Object to perform the UndoCheckOut operation on. The S1StructuredIdentifer shall be represented as valid S1000D URN syntax (e.g., URN:S1000D:DMC-S1000D-A-07-05-0000-00A-000A-A_I-001_W-00_L-SX_C-US
-
SessionID (xs:string): The session identifier for the connected end user.
Output Parameters:
Error Conditions:
-
INVALID_STRUCTURED_IDENTIFIER
-
INVALID_SESSION_IDENTIFIER
-
SESSION_NOT_ACTIVE
-
OPERATION_NOT_PERMITTED
-
CSDB_OBJECT_NOT_CHECKED_OUT
CheckIn
The CheckIn operation allows an authoring tool or application to make the private working copy of the CSDB Object the current version of the CSDB Object in the CSDB Management System.
The CheckIn operation signifies to a CSDB Management System that a learning content authoring tool or application would like to persist changes made to the CSDB Object identified and unlock the object for future operations. The CheckIn operation requires the CSDB Management System to perform appropriate CSDB Management System defined check in procedures. Minimally, it is required that the CSDB Management System performs the following:
-
increases the inWork number by 1. The inWork number is used to track the different drafts of the CSDB Object. The inWork number is part of the data module identification information found within the Identification and status section of a data module. If the inWork number was changed during the authoring process, the value will be ignored and set according to this rule by the CSDB Management System. This will avoid any discrepancies with understanding the requirements of the inWork number by authors.
-
persists the CSDB Object identified through the input parameter
-
unlocks the CSDB Object identified through the input parameter
Although not required by this specification, the CSDB Management System could validate the CSDB Object in accordance with requirements of the S1000D Specification (e.g., schema validation). The CSDB Management System can use the schemaLocation attribute to determine the schemas to be used for validation purposes. The schemaLocation attribute is required to be present in the S1000D CSDB Objects. Prior to issuing the CheckIn operation, applications could possibly reduce validation errors by using the S1000D Schemas and any identified Business Rules Exchange (BREX) data modules associated with the object.
This operation can only be performed by a user who has the rights to perform the operation:
-
The original user who checked out the file, or
-
A systems administrator
NOTE: Because a CheckIn can be performed across sessions, the CSDB Management System must design a way to track who has checked out what CDSBObjects. How this is implemented is outside the scope of this specification.
Input Parameters:
-
S1StructuredIdentifier (S1StructuredIdentifier_Type): The S1000D structured identifier that represents the CSDB Object to check in. The S1StructuredIdentifer shall be represented as valid S1000D URN syntax (e.g., URN:S1000D:DMC-S1000D-A-07-05-0000-00A-000A-A_I-001_W-00_L-SX_C-US).
-
CSDBObject (Attachment_Type): This parameter represents the CSDB Object being checked in.
-
SessionID (xs:string): The session identifier for the connected end user.
Output Parameters:
-
NewInWorkNumber (xsd:string): This output parameter represents the final number used by the CSDB Management System for the inWork number. If an InWork number is returned, the operation was successful.
Error Conditions:
-
INVALID_STRUCTURED_IDENTFIER
-
INVALID_SESSION_IDENTIFIER
-
SESSION_NOT_ACTIVE
-
OPERATION_NOT_PERMITTED
-
CSDB_OBJECT_NOT_CHECKED_OUT
-
CSDB_OBJECT_NOT_VALID_TO_S1000D
