Report to PALS Cataloging User Group April 26, 2005
The validation work group was formed in March to review and correct the tables that the Aleph Cataloging module uses to validate MARC bibliographic and authority records.
Members are Mary Ann Greenwald (PALS), Stephanie McConnell (Bemidji State), Lori Pesik (Saint Mary’s), Pam Pitts (Crown College), Monica Ralston (Minn. Historical Society), Jessica Schomberg (Mankato State), and Larry Spiess (PALS).
The group has met twice via WebMeeting (March 23 and April 13) and has a WebBoard to discuss issues and share files.
First, we are working on the check_doc tables for bibliographic records, which indicate
which fields are allowed,
which indicators and subfields are allowed for each field,
whether a subfield is mandatory, and
whether a subfield is repeatable.
For the past month, we have been working on the table check_doc_line, which covers fields 010-999. We have compared check_doc_line with OCLC Bibliographic Formats and Standards and MARC 21 Bibliographic. In cases where questions arose, we made the following decisions about what to allow:
Elements that are obsolete in MARC 21 are not allowed. Most are already absent from check_doc_line. Aleph will give an error saying that the field is not valid.
Elements that are in OCLC Bib Formats but not in MARC 21 are allowed, but will generate a message indicating the restrictions on use.
Elements that are in MARC 21 but not in OCLC Bib Formats are allowed.
Elements that say “do not use” in OCLC Bib Formats but that are valid in MARC 21 are allowed, but will generate a message stating that OCLC says not to use.
Local fields are allowed. Mary Ann consulted various sources and compiled a list of local fields, but the group still has to determine which of these to include and which indicators and subfields are allowed for each.
After completing work on check_doc_line (fields 010-999), the group will work on check_doc tables for bibliographic fields 006, 007, 008, and LDR. Then, the group will work on tables that define dependencies among bibliographic fields, indicators, and subfields.
Finally, the group will repeat the same work for validation tables for authority records and holding records.
