Yee's Cataloging Rules

Martha M. Yee has updated her suggested cataloging rules and RDF model.
This is still a work in progress, so I would love to hear more suggestions for improvement from anyone who can afford the time to look it all over. James Weinheimer is helping me work on a wiki site for the cataloging rules, so keep your eye on this space (smile)...

Work Begins on the RDA Vocabularies

The DCMI/RDA Task Group was formed in April of 2007, when members of the Joint Steering Committee for the Development of RDA, Dublin Core and the W3C Semantic Web Deployment Working Group met in London. At that meeting, two tasks relating to RDA vocabularies were identified:
  1. definition of an RDA Element Vocabulary
  2. disclosure on the public web of RDA Value Vocabularies using RDF/RDFS/SKOS technologies
The RDA Vocabularies Project proposes to surface these underlying bibliographic elements in the form of Semantic Web vocabularies, thereby making them reusable in Semantic Web applications and citable with Uniform Resource Identifiers (URIs). This will be based on RDF (Resource Description Framework), a generic grammar for expressing data for use not just by humans, but also in automated processes of data integration and "intelligent" reasoning.

The work will be lead by the DCMI/RDA Task Group chairs: Gordon Dunsire of the University of Strathclyde and Diane Hillmann of Cornell University (with support from Tom Baker of the Dublin Core Metadata Initiative). Other participants working closely with the project are:
  • Karen Coyle (independent consultant well known in the library world)
  • Alistair Miles (editor for the Simple Knowledge Organization System (SKOS) and member of the W3C SWDWG)
  • Mikael Nilsson (researcher in the Knowledge Management Research Group, Royal Institute of Technology, Sweden and co-chair of the DCMI Architecture Forum)
Partial funding for the effort has been secured, and sources of additional funding are still being sought. Potential funders should contact Diane Hillmann at dih1@cornell.edu for further information.

Public information on the progress of the project is available on the DCMI/RDA Task Group wiki. Continuing discussion on the work of the Task Group will take place on the public mailing list maintained by the task group and available for open subscription. Feedback, comment and experimentation with the products that the group will be presenting is both welcome and essential to the success of the work.

MARC and RDF

Semantic MARC, MARC21 and the Semantic Web by Rob Styles, Danny Ayers, and Nadeem Shabir is available as a preprint.
The MARC standard for exchanging bibliographic data has been in use for several decades and is used by major libraries worldwide. This paper discusses the possibilities of representing the most prevalent form of MARC, MARC21, as RDF for the Semantic Web, and aims to understand the tradeoffs, if any, resulting from transforming the data. Critically our approach goes beyond a simple transliteration of the MARC21 record syntax to develop rich semantic descriptions of the varied things which may be described using bibliographic records. We present an algorithmic approach for consistently generating URIs from textual data, discuss the algorithmic matching of author names and suggest how RDF generated from MARC records may be linked to other data sources on the Web.
