Why to MARC at all?

All the bibliographic data in the CDSware system are internally represented in the MARC 21 format. There are several good reasons for this:

Choosing MARC representation of your metadata

Basically, you are in one of the following three situations:

  1. You do not care much about internal MARC metadata structure as far as you can work with "more meaningful" metadata concepts like author, abstract, title, etc. In this case we simply recommend you to stick to CDSware defaults that preset for you the most commonly used metadata fields (in alphabetical order; non-exhaustive list):

     METADATA CONCEPT             PROPOSED MARC 21 REPRESENTATION
     ------------------------     -------------------------------
     Abstract                     520 $a
     Author, first                100 $a
     Author(s), additional        700 $a
     Collection identifier        980 $a
     Email                        8560 $f
     Imprint                      260 $a,b,c; 300 $a 
     Keywords                     6531 $a
     Language                     041 $a
     OAI identifier               909CO $o
     Publication info             909C4 $* [many subfields]
     References                   999C5 $* [many subfields]
     Primary report number        037 $a [unique throughout the system!]
     Additional report number(s)  088 $a
     Series                       490 $a,v
     Subject                      65017 $a
     Title                        245 $a
     URL (e.g. to fulltext)       8564 $u, $z 
     
     

    The advantage of using these CDSware defaults is that you can use pre-defined configurations of BibConvert, BibFormat, and BibIndex.

  2. You do not care much about internal MARC metadata structure, so you are using CDSware defaults, but you need to introduce a new metadata concept. For example, you would like to store also the document shelf number, and you want to make it separately searchable. In this case you are free to choose any MARC tag of your own, for example 963 $6. After that you would configure CDSware as follows:

    which should give you the functionality you need.

  3. You have some constraints on the MARC level, for example you would like to use MARC markup scheme of your own. You are free to define your own scheme and even invert the meaning of our default configurations. For each field you would simply follow the above-mentioned configuration procedure.

    However, when designing your own MARC scheme, you need to think of two CDSware-related restrictions:

    These two restrictions were introduced in order to keep CDSware bibliographic tables both simple and fast. As explained above, we believe that any good database design will avoid these techniques anyway.

MARC representation in use at CERN

MARC schema that is used in the CERN library differs in some ways from the schema found in the CDSware default configuration and in the demo records, described under point 1 of the preceding section. This has got both an advantage and a disadvantage: (i) an advantage that it permits us to easily test the behaviour of CDSware in the context of different metadata schemata used by different CDSware installations in the world, and (ii) a disadvantage that the default schema may be prone to different extensions by different CDSware installations in the world, while these extensions could have possibly been avoided by building local extensions on top of a richer default. (There will probably always be local tag schema differences due to various local cataloguing traditions.)

As an example of an extensive MARC schema that could provide a possible richer default for the CDSware installations in the world, we are listing below all MARC tags that are in production in the CERN Library. Please note that in some cases the metadata choice was dictated by local policy of a Swiss library network that the CERN Library is participating at, and that it may deliberately differ from the Library of Congress recommendations in some places to some extent. (See especially tags 024, 035, 037, 518, 700, 710, 711, 720, 721, 722, 723, 724, 725, 773, 866.)

If this schema is found interesting, we may also provide CERN BibFormat etc configurations that implement it for CDSware.

 
                    GUIDE TO MARC21 TAGS FOR CERN AND CDSWARE 
 
 an attempt to present the actual setup of different MARC tags in use in AL500 
                              at CERN
 
                            Maja Gracco
                            1 September 2004
                            
 NOTE: 
 1. The abbreviations "NR" and "R" are MARC21 standards and stands for 
 "Not repetitive" and "Repetitive". At CERN the rule is to make a tag repetitive,
  when possible [only tags 1xx are not-repetitive] but to make subfields 
 non-repetitive [there are a couple of exceptions].
 2. Subfield codes in AL300 are marked with $$ and subfield codes in AL500
 are marked with $.
 3. When different indicators are used, the tag will be repeated for each of 
 them like tag 246
 4. [CERN] indicates, that some modifications have been done to the tag to 
 suit the CERN Library needs, like adding one or more subfield code(s) like 
 tag "773" or slightly change the content of the field like tag "037"
 5. [CDSware/MySQL] indicates, that this tag is exlusively used for CDSware; 
 this technic is mainly used, when AL500 proposes an alpha-tag like "BAS"
 6. To be able to find previous fields/tags mentioned under the title:

               "PAR" link is automatically built in the opposite direction.

               BIB to HOL.
               ADM link from ADM record to BIB record. Link is built from
               BIB to ADM.
               ANA is a link between bibliographic records of different levels.
               When an anayltic link is created the system generates UP / DWN
               links between the two records and an item link between the source
               record and the item that corresponds to it (according to vol.,
               part,year and pages) on the ADM record of the second record.
               ITM links are created between a Bibliographic record and an ADM
               record when there is no relationship between the two Bib records,
               for example when two items are bound together. [NR} - [ARC]

          $a - link type
               UP link to another BIB type record. A record can have only one
               link of this type. "DN" link is automatically built in the
               opposite direction.
               DN "down" link to another BIB type record. Multiple links
               are possible. "UP" link is automatically built in the
               opposite direction.
               PAR parallel link from BIB record to BIB record.
               "PAR" link is automatically built in the opposite direction.
               HOL link from HOL record to BIB record. Link is built from
               BIB to HOL.
               ADM link from ADM record to BIB record. Link is built from
               BIB to ADM.
               ANA is a link between bibliographic records of different levels.
               When an anayltic link is created the system generates UP / DWN
               links between the two records and an item link between the source
               record and the item that corresponds to it (according to vol.,
               part,year and pages) on the ADM record of the second record.
               ITM links are created between a Bibliographic record and an ADM
               record when there is no relationship between the two Bib records,
               for example when two items are bound together. [NR} - [ARC]
