    Abstract
    This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

    Abstract
    Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22) will be issued simultaneously in print and web versions in July 2003. The new edition is the first full print update to the Dewey Decimal Classification system in seven years-it includes several significant updates and many new numbers and topics. DDC 22 also features some fundamental structural changes that have been introduced with the goals of promoting classifier efficiency and improving the DDC for use in a variety of applications in the web environment. Most importantly, the content of the new edition has been shaped by the needs and recommendations of Dewey users around the world. The worldwide user community has an important role in shaping the future of the DDC.

    Abstract
    Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools

    Abstract
    Describes what needs to be done to prepare knowledge organization tools for the future in the context of 7 challenges facing classification systems. Discusses work underway in the DDC to address each of these challenges focusing on: Updating efforts; features of Dewey for Windows; the OCLC projects; multilingual use of Dewey; and the development of a new database system with an authority control file for entries in the Relative Index and for linked entries from other theisauri

    Abstract
    This paper explores the history, uses cases, and future plans associated with availability of the Dewey Decimal Classification (DDC) system as linked data. Parts of the Dewey Decimal Classification (DDC) system have been available as linked data since 2009. Initial efforts included the DDC Summaries (the top three levels of the DDC) in eleven languages exposed as linked data in dewey.info. In 2010, the content of dewey.info was further extended by the addition of assignable numbers and captions from the Abridged Edition 14 data files in English, Italian, and Vietnamese. During 2012, we will add assignable numbers and captions from the latest full edition database, DDC 23. In addition to the "old friends" of different Dewey language versions, institutions such as the British Library and Deutsche Nationalbibliothek have made use of Dewey linked data in bibliographic records and authority files, and AGROVOC has linked to our data at a general level. We expect to extend our linked data network shortly to "new acquaintances" such as GeoNames, ISO 639-3 language codes, and Mathematics Subject Classification. In particular, we will examine the linking process to GeoNames as an example of cross-domain vocabulary alignment. In addition to linking plans, we report on use cases that facilitate machine-assisted categorization and support discovery in the Semantic Web environment.

    Abstract
    The 4 volume set of the 21st edition of the DDC was published in Jul 1996, and its electronic version, Dewey for Windows (on CD-ROM) was introduced the following month. Presents some highlights from both, and gives an update on research that is aimed at helping the DDC continue to be the knowledge organization tool for the next century. Ed. 21 includes 3 major revisions: 350-354 Public adminsitration; 370 Education; and 560-590 Life sciences. Changes have been made in other disciplines to address cultural, social and political issues, including an attempt to reduce the Christian bias in 200 (Religion). Further expansions to computer science have been required. Several structural changes should make DDC21 easier to apply and exploit the new possibilities of electronic distribution.

    Abstract
    The Functional Requirements for Subject Authority Data (FRSAD) conceptual model identifies entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as a subject of a work) and nomen (any sign or sequence of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question, can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system is used as a case study to test applicability of the FRSAD model for classification data, and as a springboard for a general discussion of issues related to the use of FRSAD for the representation of classification data.

    Content
    This paper explores the feasibility of developing mixed translations of the Dewey Decimal Classification (DDC system in countries/language groups where English enjoys wide use in academic and social discourse. A mixed translation uses existing DDC data in the vernacular plus additional data from the English-language full edition of the DDC to form a single mixed edition. Two approaches to mixed translations using Norwegian/English and Swedish/English DDC data are described, along with the design of a pilot study to evaluate use of a mixed translation as a classifier's tool.

    Abstract
    This entry discusses the Dewey Decimal Classification's value proposition as a general knowledge organization system in terms of basic design, history, ongoing development, translations, mappings, applications, and research. The authors conclude with prospects for use of the DDC inside and outside of libraries.

    Abstract
    In 2003, OCLC published Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22), in print and Web versions. The changes and updates in the new edition reflect a modern view of knowledge structures and address the general needs of Dewey users. The content of DDC 22 has been shaped by a number of social, geopolitical, and technical trends. The World Wide Web has provided a vehicle for more frequent distribution of updates to the DDC, and a medium for direct communication with Dewey users around the world. In addition to updating the system itself, other strategies are needed to accommodate the needs of the global Dewey user community. Translation of the system is one approach; another is mapping. Mapping terminology to the DDC is a strategy for supporting effective local implementation of the system while maintaining the internal cohesiveness of the DDC. This paper explores the usefulness of mapping terminology from English-language general subject headings lists produced outside the U.S.

    Abstract
    Options currently provided in the Dewey Decimal Classification system are reviewed. Options are an appropriate mechanism in a general purpose classification used by different kinds and sizes of libraries around the world. Dewey provides the universal option of close versus broad classification. Options also are provided to give emphasis to jurisdiction; racial, ethnic, or national group; language; topic; or other specific characteristics. Various devices are detailed or suggested to introduce options. Options may be an impediment to retrieval of information across systems. Options should not be introduced as a substitute for the appropriate placement of a topic in the Classification. Options help accommodate cultural differences in the Classification, and provide a mechanism for emphasizing topics of local importance.

    Abstract
    The German translation of the Dewey Decimal Classification (DDC) system has had a transformational effect on the DDC in terms of DDC content, the underlying translation support system, representation of the DDC in electronic files, new uses of the DDC, mappings, collaboration with the Dewey editorial team and other members of the worldwide Dewey community, and ongoing research and development. This paper highlights some of the contributions of the German translation to each of these areas produced under the visionary leadership of Magda Heiner-Freiling.

    Abstract
    This paper reports on an ongoing investigation of mixed translation models for the Dewey Decimal Classification (DDC) system to support classification and access. A mixed translation uses DDC classes in the vernacular to form the basic framework of the mixed edition; English-language records are ingested directly to complete hierarchies where needed. Separate indexes of available terminology in the vernacular and English are provided. Specific Norwegian and Swedish mixed models are described, along with testing results of the Norwegian model. General implications of mixed translation models for knowledge organization in multilingual environments are considered.

    We describe a new information technology for knowledge organization: the development of a Web-accessible "taxonomy" server based on the top levels of the Dewey Decimal Classification (DDC) system. The server offers a publicly accessible automatic metadata creation tool that returns metadata encoded in XML. This paper discusses the role of the DDC in the project. Included in the metadata is automatic subject assignment based on the DDC and represented in XML. The project also provides a public browsing interface that uses the DDC as its underlying structure the DDC

    Abstract
    This article explores the history of the representation of the Dewey Decimal Classification (DDC) in the Machine Readable Cataloging (MARC) formats, with a special emphasis on the development of the MARC classification format. Until 2009, the format used to represent the DDC has been a proprietary one that predated the development of the MARC classification format. The need to replace the current editorial support system, the desire to deliver DDC data in a variety of formats to support different uses, and the increasingly global context of editorial work with translation partners around the world prompted the Dewey editorial team, along with OCLC research and development colleagues, to rethink the underlying representation of the DDC and choose the MARC 21 formats for classification and authority data. The discussion is framed with quotes from the writings of Nancy J. Williamson, whose analysis of the content of the Library of Congress Classification (LCC) schedules played a key role in shaping the original MARC classification format.
