The general definition used by OCLC to implement the capabilities for setting institution holding symbols.

Purpose

OCLC supports setting and deleting institution holding symbols via the Z39.50-1995 DatabaseUpdate Extended Service Definition. The following is the general definition of how OCLC has implemented these Z39.50-1995 capabilities in its target server. Refer to The Z39.50 Document for more information about the Extended Services DatabaseUpdate Service.

Service definitions

The OCLC Z39.50 server does not maintain a task package database. All databaseUpdate tasks are assumed waited. The OCLC Z39.50 server DatabaseUpdate Extended Service supports only the creation of a task package that will be returned in the response.

Delete holdings

databaseName =  "oclc_oluc_holdings"
    action       =  elementUpdate
    suppliedRecords ::= SEQUENCE OF SEQUENCE {record  [4] IMPLICIT EXTERNAL}
    -- note only one record will be accepted per request.

Record numbers

8-digit

If the number is 8 or fewer digits, the form should be “ocm” + OCLC accession number. The number may or may not contain leading zeroes and a single trailing space.

Example: These two variations both result in the same record being updated:

  • ocm1
  • ocm00000001

9-digit

If the number is 9 digits, the form should be “ocn” + OCLC accession number. The number will not contain a trailing space.

Example: ocn100000000

10-digit

If the number is 10 or more digits, the form should be “on” + OCLC accession number. The number will not contain a trailing space.

Example: on1234567891

The institution symbol associated with the authorization supplied in the Init Service will be used to update/delete the holdings database.
