Amendment Concerning: Update Extended Service ASN.1

Reference in Document: Appendix 8, EXT.2, ESFormat-Update

Reference in Maintenance Agency page: Update ES ASN.1

Note: Development of this amendment occurred in conjunction with the definition of the Update Schema.

Amendment:

1. In the original Update definition (within Z39.50-1995), OriginPartToKeep was defined as follows:

         OriginPartToKeep ::= SEQUENCE{
               action                   [1] IMPLICIT INTEGER{
                               recordInsert           (1),
                               recordReplace          (2),
                               recordDelete           (3),
                               elementUpdate          (4)},
               databaseName      [2] IMPLICIT InternationalString,
               schema            [3] IMPLICIT OBJECT IDENTIFIER OPTIONAL,
               elementSetName    [4] IMPLICIT InternationalString OPTIONAL}
                                                             }           
   

   This amendment changes it to:

      OriginPartToKeep ::= SEQUENCE{
         action              [1] IMPLICIT INTEGER{
                                   recordInsert      (1),
                                   recordReplace     (2),
                                   recordDelete      (3),
                                   elementUpdate     (4),
                                   specialUpdate     (5)},
         databaseName        [2] ......
         schema              [3] ......
         elementSetName      [4] .......
         actionQualifier     [5]  IMPLICIT EXTERNAL OPTIONAL}    
   

2. In the original Update definition (in Z39.50-1995) TaskPackageRecordStructure was defined as follows:

      TaskPackageRecordStructure ::= SEQUENCE{
         recordOrSurDiag     [1] CHOICE {
               record      [1] IMPLICIT EXTERNAL,
                     -- Choose 'record' if recordStatus is 'success', and
                     -- elementSetName was supplied.
             diagnostic  [2] DiagRec
                   -- Choose 'diagnostic', if RecordStatus is failure.
                                } OPTIONAL,
                    -- The parameter recordOrSurDiag will thus be omitted only
                    -- if 'elementSetName' was omitted and recordStatus is
                    -- 'success'; or if record status is 'queued' or in
                    -- 'process'.
         correlationInfo     [2] ...
         recordStatus        [3] ...
                             success     (1),
                             queued      (2),
                             inProcess   (3),
                             failure     (4)}}
   

   This amendment changes it to the following:

      TaskPackageRecordStructure ::= SEQUENCE{
         recordOrSurDiag           [1] CHOICE {
                     record                 [1] IMPLICIT EXTERNAL,
                                -- ........
                     surrogateDiagnostics   [2] IMPLICIT 
                                   SEQUENCE OF DiagRec
                                  -- Choose 'SurrogateDiagnostics', if
                                  -- RecordStatus is failure.
                                                } OPTIONAL,
                          -- ......
         correlationInfo           [2] ...
         recordStatus              [3] ...
         supplementalDiagnostics   [4] IMPLICIT 
                        SEQUENCE OF DiagRec OPTIONAL}
   END
   

Status: This was endorsed by the ZIG, August 1998, but will not be progressed further as an amendment. Instead, a new object identifier is assigned to the revised Update Extended Service definition.
