CDL-T Processing and Display Guidelines


The following guidelines have been developed in accordance with recommendations made by the SOPAG Electronic Resources Cataloging Taskforce. 

A. GLOSSARY 

Location Segment: 

The location segment (also referred to as the 'holdings segment') is the basic unit of local information in the MELVYL record. One segment is generated for each valid unique location code in the input record.  A record can have multiple location segments, each consisting of (some of) the following major components. 

M=Monograph     P=Periodicals 

       920 location code               (M,P) 

       928 pre-call# note              (M,P) 

       930 call number                  (M,P) 

       932 post call number note   (M,P) 

       934 summary holdings        (M) 

       935 local note                    (M,P) 

       950 summary holdings        (P) 

For a fuller description of the MELVYL record format, see Technical Report No. 3 - Record Format for the MELVYL Catalog, available at ftp://ftp.dla.ucop.edu/pub/techreport/recformat.txt
 

Maintenance Key: 

A Maintenance Key is created by CDL/T for every record input into the CAT and PE databases where it is used to identify records for update.  It consists of three main parts, all contained in the 901 field: 

 901 $a Technical Processing ('TP') Code - represents the system that output the record to CDL/T. 
        $b Record Identification Number - taken from the incoming record ID. 
        $c Maintenance Code - data representing specific campuses, used to make maintenance keys unique. 

Example:  901 $a I  $b 1234567  $c RVB 
 

B. NORMALIZATION PROCESSING 

In addition to standard normalization and preparation for the MELVYL databases, the CCA/CDL records will receive special processing as shown below.  Reference is made to CCA record fields in the 9XX range.  Although the exact 9XX fields cannot be known until the CCA has been chosen, the ones to be output by the CCA have been defined as follows for this document.

 CCA RECORD FIELD   CONTENTS                                  MELVYL RECORD FIELD 



 920 $a                            Location code                                  920 $a 

 932 $a                            Access note                                     932 $a 

 934 $a                            Monograph summary holdings          934 $a 

 950 $a                            Serial summary holdings                   950 $a

1. Maintenance Key:  CDL-T 901 field

Create a CDL-T maintenance key from the CCA record ID. This  unique identifier will be used in record maintenance and update. 

      901 $a I $b 1229479 $c CDB 
 

2. Location Codes:  CDL-T 920 fields

Output a 920 CDL location code for each incoming CCA record, even though there will be no CCA supplied CDL code.  In addition, output a 920 for each 920 in the CCA input record.  The incoming 920s represent the campuses that have access to the title through CDL. 

      920 $a CDL  (supplied by CDL-T) 

      920 $a UCSC (generated from 920 in input record) 

      920 $a UCSD (generated from 920 in input record) 
 

3. Call Numbers:  CDL-T 930 fields 

Do not output 930 fields in CCA/CDL records. 
 

4. Post Call Number Notes:  CDL-T 932 fields

This field will contain information about access restrictions and will be created as follows.  If the incoming record contains 932 fields, move the contents of those fields to CDL-T 932 fields.  If it does not, create a 932 field from the first $z in the first 856 in the record.  If the record contains neither a 932 nor an 856 $z, do not create a 932 note. 

      932 $a Access restricted to:  UCSC, UCSD. 

      932 $a Password required.  Ask at service desk. 
 

5. Summary Holdings, Monographs:  CDL-T 934 field

This field will specify what materials are included in the electronic resource and will be created as follows.  If the incoming monograph record has a 934 field, move the contents of  the field to a CDL-T 934 field.  If it does not, create a 934 from the  $3 in the first 856 in the record.  If the record contains neither a 934 nor an 856 $3, do not create a 934 field. 

      934 $a v.19-   available online. 
 

6. Summary Holdings, Periodicals:  CDL-T 950 field 

This field will specify what materials are included in the electronic resource and will be created as follows.  If the incoming serial record has a 950 field, move the contents of that field to a CDL-T 950 field.  If it does not, create a 950 from the $3 in the first 856 in the record.  If the record contains neither a 950 nor an 856 $3, do not create a 950 field. 

      950 $a Latest five years available online. 
 

7. CDL Directory Data:  CDL-T 980, 982, 984 fields 

These fields will contain information that will be extracted and used in CDL Directory records via a process as yet to be determined.  The fields are: 

      980 $a,$b,$c:  CDL Directory subject vocabulary 

      982 $a:  CDL Directory format 

      984 $a:  CDL Directory provider 

If the incoming record contains 980, 982, or 984 fields output the fields as input. 
 

8. Base Record Calculation 

Assign a base record weight to CCA/CDL records so that the records will become the base records in the MELVYL databases. 
 

9. Cataloging units

Assign a CDL cataloging unit to each incoming record. 
 

10. AT Searching

Enable an 'AT CDL' search that will retrieve the CCA/CDL records.  In addition, for each campus subscriber (as represented by the 920 location codes), turn on campus bits so that the CCA/CDL records will be retrieved in <AT CAMPUS> searches. 
 

11. 776 $x Indexing

Index the 776 $x for purposes of retrieval by ISSN and linking to A&I databases. 
 

C. DISPLAY PROCESSING

Special MELVYL display processing will be required as follows. 

1. Location Segment Suppression

When displaying CCA/CDL records, suppress the display of campus location segments.  Show only the CDL location segment. 
 

2. Call numbers

Leave the call number areas blank when displaying local information for the CCA/CDL record. 
 

3. 856 fields

A group separate from the Taskforce (with representative from CDL and the campuses) be working on recommendations for improving current 856 displays.  The Taskforce itself has looked at some alternatives that include the following: 

     a.    Provision of campus labels preceding each 856, showing 'ownership' of the field. 

     b.    Removing the label 'Electronic location' that appears before each 856 field in the SHORT MELWEB 
            display and supplying it one time only, as in the LONG display. 

     c.    Displaying related electronic locations (when they can be identified by a second indicator of  '2' in  the 856) 
            in a group separate from the 856s for the title itself. 
 

D. DISPLAY EXAMPLES 

Examples do not represent actual CDL titles but are meant to demonstrate format and data placement.  856 displays do not necessarily represent how this information will eventually display in the MELVYL databases.
