FAST: fasetna uporaba predmetnega izrazja ( file )
1 edition published in 2003 in Slovenian and held by 3 libraries worldwide
Library of Congress Subject Headings Scheme (LCSH) je najpogosteje uporabljan in najbolje sprejet slovar predmetnih oznak za splošno uporabo. Dejansko je to splošen kontrolirani slovar, ki ga mnoge države uporabljajo za model pri razvijanju sistemov predmetnih oznak. Vendar pa kompleksna skladnja in pravila za oblikovanje oznak zaradi potrebe po visoko kvalificiranem osebju omejujejo njegovo uporabo in zmanjšujejo učinkovitost avtomatizirane normativne kontrole. Najnovejše težnje, ki so posledica hitrega razvoja spleta, zahtevajo spremembe v sistemih bibliografske kontrole, ki naj bi bili enostavnejši za uporabo in razumevanje - predmetne oznake pri tem niso izjema. Za oblikovanje FAST-a je namen prilagoditve LCSH-ja s poenostavitvijo skladnje ta, da se obdrži bogat besedni zaklad LCSH-ja, ob tem pa zagotovi enostavnejše razumevanje, kontrola in uporaba. Novi sistem ostane skladen z LCSH-jem v smeri navzgor, kar pomeni, da je mogoče vsak sklop predmetnih oznak LCSH pretvoriti v predmetne oznake FAST
Two paths to interoperable metadata by Carol Jean Godby( file )
1 edition published in 2003 in English and held by 3 libraries worldwide
This paper describes a prototype for a Web service that translates between pairs of metadata schemas. Despite a current trend toward encoding in XML and XSLT, we present arguments for a design that features a more distinct separation of syntax from semantics. The result is a system that automates routine processes, has a well-defined place for human input, and achieves a clean separation of the document data model, the document translations, and the machinery of the application
A repository of metadata crosswalks by Carol Jean Godby( file )
1 edition published in 2004 in English and held by 2 libraries worldwide
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
Toward element-level interoperability in bibliographic metadata by Carol Jean Godby( file )
1 edition published in 2008 in English and held by 2 libraries worldwide
This paper discusses an approach and set of tools for translating bibliographic metadata from one format to another. A computational model is proposed to formalize the notion of a 'crosswalk'. The translation process separates semantics from syntax, and specifies a crosswalk as machine executable translation files which are focused on assertions of element equivalence and are closely associated with the underlying intellectual analysis of metadata translation. A data model developed by the authors called Morfrom serves as an internal generic metadata format. Translation logic is written in an XML scripting language designed by the authors called the Semantic Equivalence Expression Language (Seel). These techniques have been built into an OCLC software toolkit to manage large and diverse collections of metadata records, called the Crosswalk Web Service
Form subdivisions their identification and use in LCSH by Edward T O'Neill( file )
1 edition published in 2001 in English and held by 2 libraries worldwide
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 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

Encoding application profiles in a computational model of the crosswalk by Carol Jean Godby( file )
1 edition published in 2008 in English and held by 1 library worldwide
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 'broadernarrower' 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

Dublin Core metadata semantics an analysis of the perspectives of information professionals by Jung-ran Park( file )
1 edition published in 2009 in English and held by 1 library worldwide
This study examines Dublin Core (DC) metadata semantics drawn from the perspectives and experiences of cataloguing and metadata professionals. The study ascertains the extent of difficulty in applying the DC metadata elements encountered by these professionals and examines factors engendering such difficulties during the metadata application process. Comments drawn from the survey participants (n = 141) show that conceptual ambiguities (41%) and semantic overlaps (45%) of the surveyed DC metadata elements are the most frequently cited factors causing difficulty and confusion, in turn leading to variant interpretations of DC metadata elements. This has the potential to bring forth inconsistent and inaccurate applications and implementation of the DC standard across institutions which can directly affect semantic interoperability across digital repositories. The high degree of difficulty (55.3%) engendered by the Relation field indicates that further examination of this element is needed
FAST : Faceted Application of Subject Terminology by Edward T O'Neill( Article )
1 edition published in 2003 in English and held by 1 library worldwide
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 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

Metadata switch : thinking about some metadata management and knowledge organization issues in the changing research and learning landscape by Lorcan Dempsey( file )
1 edition published in 2005 in English and held by 1 library worldwide
The academic library is not an end in itself. It supports research, learning and scholarship, and it must adapt as research and learning behaviors change in a network environment. The papers in this volume give a good sense of the challenges posed by such developments and the manifold library response. This paper briefly considers some of these issues, and takes them as its context, but quickly moves to a very specific emphasis. It considers how such library responses create new metadata management and knowledge organization questions, and it then outlines some of the work in OCLC Research which responds to these issues
Crosswalking metadata in the OCLC CORC Service by Eric Childress( file )
1 edition published in 2001 in English and held by 1 library worldwide
The new OCLC CORC service will offer users the ability to create, edit, or export metadata in several standard views, chiefly MARC and Dublin Core. This is made possible by a crosswalk, a specification for converting metadata from one standard to another. The article describes the philosophy and approach guiding the OCLC CORC service's implementation of its crosswalk capabilities

Presents a conceptual framework of the nature and scope of the evolving scholarly record to help organize and drive discussions about the evolution of scholarship. The framework presents a high-level view of the categories of materials the scholarly record potentially may encompass, as well as the key stakeholder roles -- and configurations of those roles -- associated with the scholarly record
A faceted approach to subject data in the Dublin Core metadata record by Lois Mai Chan( Article )
1 edition published in 2001 in English and held by 1 library worldwide
The enormous volume and rapid growth of resources available on the World Wide Web and the emergence of numerous metadata schemes have spurred a reexamination of the way subject data is to be provided for Web resources efficiently and effectively. For the Dublin Core metadata record, a new approach to subject vocabulary is being investigated. This new method, called FAST (FacetedApplication of Subject Terminology), is based on the existing vocabulary in Library of Congress Subject Headings (LC), but applied with a simpler syntax than that currently used by libraries according to Library of Congress application policies. In the FAST system, non-topical (i.e., geographic, chronological, and form) data are separated from topical data and placed in different elements provided in the Dublin Core metadata record
The Evolving scholarly record by Brian F Lavoie( file )
1 edition published in 2014 in English and held by 0 libraries worldwide
This report presents a framework to help organize and drive discussions about the evolving scholarly record. The framework provides a high-level view of the categories of material the scholarly record potentially encompasses, as well as the key stakeholder roles associated with the creation, management, and use of the scholarly record. Key highlights: A confluence of trends is accelerating changes to the scholarly record's content and stakeholder roles. Scholarly outcomes are contextualized by materials generated in the process and aftermath of scholarly inquiry. The research process generates materials covering methods employed, evidence used, and formative discussion. The research aftermath generates materials covering discussion, revision, and reuse of scholarly outcomes. The scholarly record is evolving to have greater emphasis on collecting and curating context of scholarly inquiry. The scholarly record's stakeholder ecosystem encompasses four key roles: create, fix, collect, and use. The stakeholder ecosystem supports thinking about how roles are reconfigured as the scholarly record evolves. The ways and means of scholarly inquiry are experiencing fundamental change, with consequences for scholarly communication and ultimately, the scholarly record. The boundaries of the scholarly record are both expanding and blurring, driven by changes in research practices, as well as changing perceptions of the long-term value of certain forms of scholarly materials. Understanding the nature, scope, and evolutionary trends of the scholarly record is an important concern in many quarters--for libraries, for publishers, for funders, and of course for scholars themselves. Many issues are intrinsic to the scholarly record, such as preservation, citation, replicability, provenance, and data curation. The conceptualization of the scholarly record and its stakeholder ecosystem provided in the report can serve as a common point of reference in discussions within and across domains
