Transforming MARCXML to MODS

The Library of Congress has made available a revised stylesheet for transforming MARCXML to MODS version 3.1. Changes are mainly to language and classification elements (enhancements made for MODS version 3.1). There were a few errors that also were fixed.


Additions to the MARC Code Lists

Additions to the MARC Code Lists for Relators, Sources, Description Conventions Network Development and MARC Standards Office Library of Congress.

The codes listed below have been recently approved for use in MARC 21 records. The new codes will be added to the online MARC Code Lists for Relators, Sources, Description Conventions.

The codes should not be used in exchange records until after May 10, 2006. This 60-day waiting period is required to provide MARC 21 implementers time to include newly defined codes in any validation tables they may apply to the MARC fields where the codes are used. MARC Term, Name, Title Sources & Other Sources

These codes are for use in subfield $2 in Bibliographic and Community Information records in fields 600-651 and 655 and field 040, subfield $f (Cataloging Source / Subject heading/thesaurus conventions) in Authority records.

Ontologies in Topic Maps

Ontology-Driven Knowledge Organization: Enhancing UDDI Web services in Korea Using Topic Maps by Sam Gyun Oh, Eun Chul Lee, Oknam Park, and Myongho Yi appears in Proceedings 68th Annual Meeting of the American Society for Information Science and Technology (ASIST) 42.
Effective and efficient publishing and searching for Universal Description, Discovery and Integration (UDDI) Web services is important for the success of Web services. Traditional approaches such as index, thesaurus, and classification have historically dominated information representation and organization; however, they have some limitations. Ontology-driven knowledge organization [An ontology-driven knowledge organization approach] is considered one of keys to the next generation of knowledge management applications because ontology provides structure and meaning to data. This research examines how ontology-driven knowledge organization could provide benefits to current UDDI Web services.


Faceted Classification

A Hybrid Approach to Faceted Classification Based on Analysis of Descriptor Suffixes by Aaron Loehrlein, Elin K. Jacob, Kiduk Yang, Seungmin Lee, and Ning Yu appears in Proceedings 68th Annual Meeting of the American Society for Information Science and Technology (ASIST) 42
This study explores the construction of a faceted vocabulary that can be used as a mechanism for organizing Webbased resources. After analyzing the manual process of faceted vocabulary construction using existing organizational structures to identify heuristics for automating the construction process, we modeled a hybrid, semi-automatic approach to facet generation that integrates the strengths of manual and automatic methods. This approach is based on the organization of terms according to the meanings of their suffixes. Although this heuristic could not usefully organize the majority of terms of the lexicon bases to which it was applied, it nevertheless shows promise as a component of hybrid classification.

E-Prints and Tagging

This from the Connotea folks:
We've released a small code collection that enables institutional repositories running on EPrints to easily add tagging, bookmarking, and related article linking to their sites.

The TaggingTool works by connecting the repository content to either Connotea, del.icio.us, or any service based on Connotea Code. It shows tags that have been used on repository items, allows users to save the item in their own Connotea or del.icio.us accounts, and shows links to related articles.

The tool is quick and easy to install, and requires only minimal changes to an existing EPrints repository. If you're a user of a repository and would like to experiment with the TaggingTool, point your administrator at the summary of its features.

Catalog of U.S. Government Publications

There is a new version of the Catalog of U.S. Government Publications (CGP). This version of the CGP is the online public access catalog (OPAC) module of the Government Printing Office's (GPO) new integrated library system. With the availability of the new CGP Phase 1 of a larger modernization plan to replace older legacy systems is complete.

The new and improved CGP currently offers more than 500,000 records to both historical and current Government publications. These records have been created or updated since July 1976. Plans are underway to include records for publications dating back to the late 1800s.

MARC Proposals and Discussion Papers

The cover sheets for the proposals and discussion papers presented at the Midwinter meetings of the MARC Advisory Committee have been updated with the results of the discussions. They are available at:

MARC Tag of the Month

Follett's MARC Tag of the Month for March is MARC Record Sample -- Parallel Title (Book).

Metadata Survey

OCLC is looking for metadata folks to take a survey.
OCLC is working on a project that would allow us to support different types of metadata schemes, not just MARC 21 and Dublin Core. We are currently gathering information about various schemes to determine which to crosswalk or translate. We are interested in gathering information from librarians who are responsible for creating or managing records for digital resources. Attached is a link to a brief survey with some questions concerning metadata schemes and digital resources. Please take a few minutes to complete the survey. If you are not responsible for creating or managing records for digital resources at your library, please feel free to pass this survey on to someone else at your library who handles digital resources. The survey will be open for responses until March 17, 2006.

OPML 2.0

Steven Cohen (Library Stuff) persuaded Dave Winer to create an audio file discussing the 2.0 version of the OPML standard.

TLA

I just got the program for TLA 2006. What a line-up. Speakers include Jessamyn West, Jenny Levine, Michael Stephens, Stephen Abrham, as well as lots of great local and regional presenters.


MARC to XML

The Library of Congress has made an updated version of their MARC to XML Conversion Tool available.
Mrc2xml.pl is a perl program that converts a file of MARC records to XML. The resulting XML markup will reflect the MARC tags and subfields that occur in the input file of MARC records. The output file will be well-formed XML but not necessarily valid XML (i.e valid when parsed against the DTD mrcbfile.dtd). The DTD reflects only the tags present in MARC 21 (including obsolete tags). So, for instance, any 9XX local fields will cause validation to fail.

Happy Birthday

Happy Birthday to Catalogablog. Now we are four.

I started this back on March 5, 2002 on a whim. What started as an experiment now has over 2,400 posts. It has also recently been added to OCLC, #64549138. Thanks for reading and all the suggestions over the years.
