1Mixter, J. ; Childress, E.R.: FAST (Faceted Application of Subject Terminology) users : summary and case studies.
Dublin, OH : OCLC Research, 2013. 52 S.
Abstract: Over the past ten years, various organizations, both public and private, have expressed interest in implementing FAST in their cataloging workflows. As interest in FAST has grown, so too has interest in knowing how FAST is being used and by whom. Since 2002 eighteen institutions (see table 1) in six countries have expressed interest in learning more about FAST and how it could be implemented in cataloging workflows. Currently OCLC is aware of nine agencies that have actually adopted or support FAST for resource description. This study, the first systematic census of FAST users undertaken by OCLC, was conducted, in part, to address these inquiries. Its purpose was to examine: � how FAST is being utilized; � why FAST was chosen as the cataloging vocabulary; � what benefits FAST provides; and � what can be done to enhance the value of FAST. Interview requests were sent to all parties that had previously contacted OCLC about FAST. Of the eighteen organizations contacted, sixteen agreed to provide information about their decision whether to use FAST (nine adopters, seven non-adopters). ; This document presents: � a brief overview of FAST; � a brief analysis of common characteristics of parties that have either chosen to adopt FAST or chosen against using FAST; � suggested improvements for FAST vocabulary and services; � tables summarizing FAST adopters and non-adopters; and � sixteen individual "case studies" presented as edited write-ups of interviews.

2Godby, C.J. ; Smith, D. ; Childress, E.: Encoding application profiles in a computational model of the crosswalk.
In: Metadata for semantic and social applications : proceedings of the International Conference on Dublin Core and Metadata Applications, Berlin, 22 - 26 September 2008, DC 2008: Berlin, Germany / ed. by Jane Greenberg and Wolfgang Klas. Göttingen : Univ.-Verl., 2008. S.3-13.
Abstract: OCLC's Crosswalk Web Service (Godby, Smith and Childress, 2008) formalizes the notion of crosswalk, as defined in Gill,et al. (n.d.), by hiding technical details and permitting the semantic equivalences to emerge as the centerpiece. One outcome is that metadata experts, who are typically not programmers, can enter the translation logic into a spreadsheet that can be automatically converted into executable code. In this paper, we describe the implementation of the Dublin Core Terms application profile in the management of crosswalks involving MARC. A crosswalk that encodes an application profile extends the typical format with two columns: one that annotates the namespace to which an element belongs, and one that annotates a 'broader-narrower' relation between a pair of elements, such as Dublin Core coverage and Dublin Core Terms spatial. This information is sufficient to produce scripts written in OCLC's Semantic Equivalence Expression Language (or Seel), which are called from the Crosswalk Web Service to generate production-grade translations. With its focus on elements that can be mixed, matched, added, and redefined, the application profile (Heery and Patel, 2000) is a natural fit with the translation model of the Crosswalk Web Service, which attempts to achieve interoperability by mapping one pair of elements at a time.

In: Bulletin of the American Society for Information Science and Technology. 33(2006) no.5, S.xx-xx.
Abstract: Amid the debates about whether folksonomies will supplant controlled vocabularies and whether the Library of Congress Subject Headings (LCSH) and Dewey Decimal Classification (DDC) system have outlived their usefulness, libraries, museums and other organizations continue to require efficient, effective access to controlled vocabularies for creating consistent metadata for their collections . In this article, we present an approach for using Web services to interact with controlled vocabularies. Services are implemented within a service-oriented architecture (SOA) framework. SOA is an approach to distributed computing where services are loosely coupled and discoverable on the network. A set of experimental services for controlled vocabularies is provided through the Microsoft Office (MS) Research task pane (a small window or sidebar that opens up next to Internet Explorer (IE) and other Microsoft Office applications). The research task pane is a built-in feature of IE when MS Office 2003 is loaded. The research pane enables a user to take advantage of a number of research and reference services accessible over the Internet. Web browsers, such as Mozilla Firefox and Opera, also provide sidebars which could be used to deliver similar, loosely-coupled Web services.

4Godby, C.J. ; Young, J.A. ; Childress, E.: ¬A repository of metadata crosswalks.
In: D-Lib magazine. 10(2004) no.12, x S.
Abstract: This paper proposes a model for metadata crosswalks that associates three pieces of information: the crosswalk, the source metadata standard, and the target metadata standard, each of which may have a machine-readable encoding and human-readable description. The crosswalks are encoded as METS records that are made available to a repository for processing by search engines, OAI harvesters, and custom-designed Web services. The METS object brings together all of the information required to access and interpret crosswalks and represents a significant improvement over previously available formats. But it raises questions about how best to describe these complex objects and exposes gaps that must eventually be filled in by the digital library community.

Abstract: The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.

6Chan, L.M. ; Childress, E. ; Dean, R. ; O'Neill, E.T. ; Vizine-Goetz, D.: ¬A faceted approach to subject data in the Dublin Core metadata record.
In: Journal of Internet cataloging. 4(2001) nos.1/2, S.35-47.
Abstract: This article describes FAST, the Faceted Application of Subject Terminology, a project at OCLC to make Library of Congress Subject Headings easier to use in Dublin Core metadata by breaking out facets of space, time, and form. Work on FAST can be watched at its web site, http://www.miskatonic.org/library/, which has recent presentations and reports. It is interesting to see facets and Dublin Core combined, though both LCSH and FAST subject headings are beyond what most people making a small faceted classification would want or need.

7O'Neill, E.T. ; Chan, L.M. ; Childress, E. ; Dean, R. ; El-Hoshy, L.M. ; Vizine-Goetz, D.: Form subdivisions : their identification and use in LCSH.
In: Library resources and technical services. 45(2001) no.4, S.187-197.
Abstract: Form subdivisions have always been an important part of the Library of Congress Subject Headings. However, when the MARC format was developed, no separate subfield code to identify form subdivisions was defined. Form and topical subdivisions were both included within a general subdivision category. In 1995, the USMARC Advisory Group approved a proposal defining subfield v for form subdivisions, and in 1999 the Library of Congress (LC) began identifying form subdivisions with the new code. However, there are millions of older bibliographic records lacking the explicit form subdivision coding. Identifying form subdivisions retrospectively is not a simple task. An algorithmic method was developed to identify form subdivisions coded as general subdivisions. The algorithm was used to identify 2,563 unique form subdivisions or combinations of form subdivisions in OCLC's WorldCat. The algorithm proved to be highly accurate with an error rate estimated to be less than 0.1%. The observed usage of the form subdivisions was highly skewed with the 100 most used form subdivisions or combinations of subdivisions accounting for 90% of the assignments.
