    Description:
    Problem: How do I stop the z39_server from returning certain fields in GRS-1 format? 
    Can we use element sets?
    Would it be possible to have functionality to configure which fields the z39_server returns in GRS-1 format?

     

    Resolution:
    Please use the following setting:
    1) In z39_server_... .conf file, add the fix routine:
    for example:
    out-record-fix Z39

    2) In xxx01/tab/tab_fix:
    Z39 fix_doc_do_file_08 delete_fields

    3) In xxx01/tab/import/delete_fields
    define the fields to be removed, for example:
    1 049## DELETE-FIELD
    1 504## DELETE-FIELD
    1 505## DELETE-FIELD
    1 666## DELETE-FIELD
    1 852## DELETE-FIELD
    1 950## DELETE-FIELD
    1 999## DELETE-FIELD

    Restart the z39_server and the pc_server

    ********************************
    Correction to the documentation:
    "z39_server – 18"

    2.3.3.    Element Sets
    z39_server supports two special element sets, “F” and “X”.

    When the F element set is requested: 
    if the F element set is defined in ./alephe/tab/z39_server/z39_server_elements, the record is returned according to the lines defined in the table.
    if the F element set is not defined in the z39_server_elements table, a full record is returned.

    When the X element set is requested, a full record including Aleph alphanumeric fields (such as CAT, SYS, and so on) is returned. The X element set is recognized for USMARC format only. For all other formats, it is ignored.

    You can define additional element sets using the z39_server_elements configuration file.

    MARC records returned by z39_server always contain the 005 tag even if tag 005 is not defined in the element set configuration (in ./alephe/tab/z39_server/
    z39_server_elements).

    That is F is default set in the following sense: F is always recognized, also if it’s not defined by z39_server_elements.
