HOWTO MARC Your Bibliographic Data

Overview

This HOWTO guide intends to explain how to use the MARC 21 format for bibliographic records in Invenio.

For an explanation of how to use MARC in authority records, please read How to MARC authority records

Why to MARC at all?

All the bibliographic data in the Invenio 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 Invenio 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 Invenio 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 Invenio 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 Invenio as follows:

    • configure BibIndex to create a new logical field called document shelf and associate it with 963 $6 physical MARC tag;
    • run BibIndex to create word tables for the new searchable index;
    • configure WebSubmit to let the submission interface know of the existence of the new field;
    • configure WebSearch to introduce the new searchable field into collections of your choice;
    • configure BibFormat to include document shelf information in the record display on search results pages.

    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 Invenio-related restrictions:

    • There should be no clash in the meaning of the same MARC tag in two different collections. For example, the tag 100 should not mean first author in the Preprints collection and title in the Videotapes collection. The MARC tags are considered to be chosen globally, in a collection-independent way. This means that we cannot have several collections reusing the same MARC code for their own different purposes. (This should never happen in well designed database system anyway, but if you have a merge of various databases coming from various groups of users, and if you do not have the liberty to remap their MARC tags, this may be a problem.)
    • Also, our database design assumes that the order of repetitive subfields inside the same field instance does not matter. For example, let us consider the tag 100 with the value $a Foo $a Bar $a Baz. Then, the question "what is the second $a of the tag 100?" is invalid within the Invenio MARC paradigm. Invenio would store a tag like that, but not the order of repetitive subfields themselves. In our MARC paradigm, we prefer to code that information either (i) into different subfields within the same field instance (100 $a Foo $b Bar $c Baz), or (ii) into the same subfield but inside several field instances (100 $a Foo; 100 $a Bar; 100 $a Baz), according to what is more appropriate. (We think that to rely on the order of repetitive subfields inside the same field instance is a suspicious database design.)

    These two restrictions were introduced in order to keep Invenio 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 Invenio 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 Invenio in the context of different metadata schemata used by different Invenio installations in the world, and (ii) a disadvantage that the default schema may be prone to different extensions by different Invenio 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 Invenio 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 Invenio.

an attempt to present the actual setup of different MARC tags in use in AL500
                             at CERN

                  Updated by Jocelyne Jerdelet December 2009

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. [Invenio/MySQL] indicates, that this tag is exlusively used for Invenio;
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:
