Nine questions to guide you in choosing a metadata schema

Marie R. Kennedy

This article is a guide for collection developers at the point of considering a metadata schema for their digital collection. The nine questions asked in this article will assist a developer in clarifying how he wants the collection to be organized, described, and used. This article uses examples to illustrate how these questions guided the development of a digital collection built at the University of Southern California.

 

"..interesting article on automated metadata crosswalking from the new Code4lib issue:
http://journal.code4lib.org/articles/54

It details a web service that OCLC is providing for metadata conversion ("Crosswalk Web Service"); ... it gives a thorough and well-written look at the technical details of generalizing data conversion."

"The goal of the terminologies services meeting was to determine which components of a terminologies service the participants (drawn from the RLG Programs partnership and representing a wide range of different communities and roles) find the most compelling. Desired meeting outcomes included a list of the most important features and use-cases in order to help prioritize efforts of RLG Programs and OCLC Research in this area of work."

"We just issued the results of the RLG Programs Descriptive Metadata Practices survey.

We conducted this survey in July and August 2007 among 18 RLG partners in the United States and the United Kingdom, selected because they had "multiple metadata creation centers" on campus that included libraries, archives, and museums and had some interaction among them. (Ten of these partners are also represented on this focus group.) Our objective was to gain a baseline understanding of current descriptive metadata practices and dependencies, the first project in our program to change metadata creation processes."

"Metadata is often called "data about data." It has been used by various communities creating geospatial data, social and scientific data sets, enterprise applications, data warehouses, educational resources, and bibliographic data. In the traditional library world, catalog records are metadata, as they contain information about the library's collection of "data," i.e., the books and journals that make up its collections. Increasingly, libraries have been adopting emerging metadata standards such as Dublin Core, EAD, MODS, and TEI to describe, discover, preserve, manage, and provide access to electronic resources and digital objects.

This SPEC survey investigated how metadata is implemented in ARL member libraries: which staff are creating metadata and for what kinds of digital objects, what schemas and tools they use to create and manage metadata, what skills metadata staff need and how they acquire them, and the organizational changes and challenges that metadata has brought to libraries."

"The Indiana University Veriations2 and Variations3 projects use a work-based metadata model for discovery of musical sound recordings, scanned score images, and encoded score notation files. This model has been described as ³FRBR-like² and is mentioned in various discussions of FRBR-based systems, but it is not technically a FRBR implementation.

As the project team investigates long-term sustainability issues for the Variations3 software, we have begun thinking about what a truly FRBR-ized version of the metadata model would look like, and if changing to this type of model would make our system more sustainable and interoperable. As a first step towards answering these questions, members of the Variations3 project team have released a report outlining the potential application of FRBR to a system designed to deliver musical content in a library environment."

"This session explored how libraries are using emerging standards to manage and provide navigation for digital library objects. A panel of speakers reviewed their digital library implementations involving METS, MODS, PREMIS and MIX, while also providing an introduction with background information on these standards.

The aim of the program was to demonstrate how institutions can provide new methods for display, use and management of digital objects on their websites and in their repositories, using widely available open source XML tools."

"The Digital Library Federation Aquifer Metadata Working Group is proud to announce the release of the DLF Aquifer MODS Guidelines Levels of Adoption.

The Levels of Adoption document is intended to supplement the Digital Library Federation / Aquifer Implementation Guidelines for Shareable MODS Records, released in November 2006 under the auspices of the DLF Aquifer initiative. The Shareable MODS Guidelines represent a record-centric view of Aquifer's goals, whereas it is often helpful to set priorities for metadata creation with a user- and use-centric view. The newly-released Levels of Adoption document describes five general categories of user functionality that are likely to be supported by following specific recommendations from the Guidelines. It attempts to provide additional guidance to MODS implementers in the planning process by documenting what sorts of functionality is possible when certain elements of the Guidelines are
followed."

"To raise awareness about metadata and encourage its adoption, the Stock Artists Alliance is releasing its Metadata Manifesto. The Manifesto provides guiding principles and practices for anyone who creates, uses, or manages electronic images, as well as those developing digital hardware and software. Highlighting the efforts of international standards bodies and industry groups (such as IPTC and PLUS), the Manifesto stresses the urgency for industry-wide metadata adoption."
