    Abstract
    Metadata and information technology staff in libraries that are building digital collections typically extract and manipulate MARC metadata sets to provide access to digital content via non-MARC schemes. Metadata processing in these libraries involves defining the relationships between metadata schemes, moving metadata between schemes, and coordinating the intellectual activity and physical resources required to create and manipulate metadata. Actively managing the non-MARC metadata resources used to build digital collections is something most of these libraries have only begun to do. This article proposes strategies for managing MARC metadata repurposing efforts as the first step in a coordinated approach to library metadata management. Guided by lessons learned from Cornell University library mapping and transformation activities, the authors apply the literature of data resource management to library metadata management and propose a model for managing MARC metadata repurposing processes through the implementation of a metadata management design.

    Abstract
    After a review of the Kent State Libraries and Media Services Web site, a committee of librarians and staff gathered user feedback and developed a library-specific content management system (CMS) to make the move from a static HTML environment to database-driven design. This article focuses on the significant role of metadata in the CMS from the perspective of one of the site's architects and one of its content developers. This article includes figures and a biography for further reading. The work of the redesign was earlier described in a poster presentation for the 12th Annual ACRL conference.

    Abstract
    Metadata is a key aspect of our evolving infrastructure for information management, social computing, and scientific collaboration. DC-2008 will focus on metadata challenges, solutions, and innovation in initiatives and activities underlying semantic and social applications. Metadata is part of the fabric of social computing, which includes the use of wikis, blogs, and tagging for collaboration and participation. Metadata also underlies the development of semantic applications, and the Semantic Web - the representation and integration of multimedia knowledge structures on the basis of semantic models. These two trends flow together in applications such as Wikipedia, where authors collectively create structured information that can be extracted and used to enhance access to and use of information sources. Recent discussion has focused on how existing bibliographic standards can be expressed as Semantic Web vocabularies to facilitate the ingration of library and cultural heritage data with other types of data. Harnessing the efforts of content providers and end-users to link, tag, edit, and describe their information in interoperable ways ("participatory metadata") is a key step towards providing knowledge environments that are scalable, self-correcting, and evolvable. DC-2008 will explore conceptual and practical issues in the development and deployment of semantic and social applications to meet the needs of specific communities of practice.

    Abstract
    Although the issue of metadata quality is recognized as an important topic within the metadata research community, the cultural heritage sector has been slow to develop methodologies, guidelines and tools for addressing this topic in practice. This paper concentrates on metadata quality specifically within the museum sector and describes the potential of data-profiling techniques for metadata quality evaluation. A case study illustrates the application of a generalpurpose data-profiling tool on a large collection of metadata records from an ethnographic collection. After an analysis of the results of the case-study the paper reviews further steps in our research and presents the implementation of a metadata quality tool within an open-source collection management software.

    Abstract
    Knowledge management in digital libraries is a universal problem. Keyword-based searching is applied everywhere no matter whether the resources are indexed databases or full-text Web pages. In keyword matching, the valuable content description and indexing of the metadata, such as the subject descriptors and the classification notations, are merely treated as common keywords to be matched with the user query. Without the support of vocabulary control tools, such as classification systems and thesauri, the intelligent labor of content analysis, description and indexing in metadata production are seriously wasted. New retrieval paradigms are needed to exploit the potential of the metadata resources. Could classification and thesauri, which contain the condensed intelligence of generations of librarians, be used in a digital library to organize the networked information, especially metadata, to facilitate their usability and change the digital library into a knowledge management environment? To examine that question, we designed and implemented a new paradigm that incorporates a classification system, a thesaurus and metadata. The classification and the thesaurus are merged into a concept network, and the metadata are distributed into the nodes of the concept network according to their subjects. The abstract concept node instantiated with the related metadata records becomes a knowledge node. A coherent and consistent knowledge network is thus formed. It is not only a framework for resource organization but also a structure for knowledge navigation, retrieval and learning. We have built an experimental system based on the Chinese Classification and Thesaurus, which is the most comprehensive and authoritative in China, and we have incorporated more than 5000 bibliographic records in the computing domain from the Peking University Library. The result is encouraging. In this article, we review the tools, the architecture and the implementation of our experimental system, which is called Vision.

    Abstract
    Many institutional repositories have pursued a mixed metadata environment, relying on description by multiple workflows. Strategies may include metadata converted from other systems, metadata elicited from the document creator or manager, and metadata created by library or repository staff. Additional editing or proofing may or may not occur. The mixed environment brings challenges of creation, management, and access. In this paper, repository efforts at three major universities are discussed. All three repositories run on the DSpace software package, and the opportunities and limitations of that system will be examined. The authors discuss local strategies in light of current thinking on metadata creation, user behavior, and the aggregation of heterogeneous metadata. The contrasts between the mission of each repository effort will show the importance of local customization, while the experience of all three institutions forms the basis for recommendations on strategies of benefit to a wide range of librarians and repository planners.

    Abstract
    First generation scholarly research on the Web lacked a firm system of authority control. Second generation Web research is beginning to model subject access with library science principles of bibliographic control and cataloguing. Harnessing the Web and organising the intellectual content with standards and controlled vocabulary provides precise search and retrieval capability, increasing relevance and efficient use of technology. Dublin Core metadata standards permit a full evaluation and cataloguing of Web resources appropriate to highly specific research needs and discovery. Current research points to a type of structure based on a system of faceted classification. This system allows the semantic and syntactic relationships to be defined. Controlled vocabulary, such as the Library of Congress Subject Headings, can be assigned, not in a hierarchical structure, but rather as descriptive facets of relating concepts. Web design features such as this are adding value to discovery and filtering out data that lack authority. The system design allows for scalability and extensibility, two technical features that are integral to future development of the digital library and resource discovery.

    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.

    Abstract
    In the June 2003 issue of D-Lib Magazine, Kenney et al. (2003) discuss a comparative study between Cornell's email reference staff and Google's Answers service. This interesting study provided insights on the potential impact of "computing and simple algorithms combined with human intelligence" for library reference services. As mentioned in the Kenney et al. article, Bill Arms (2000) had discussed the possibilities of automated digital libraries in an even earlier D-Lib article. Arms discusses not only automating reference services, but also another library function that seems to inspire lively debates about automation-metadata creation. While intended to illuminate, these debates sometimes generate more heat than light. In an effort to explore the potential for automating metadata generation, the Digital Knowledge Center (DKC) of the Sheridan Libraries at The Johns Hopkins University developed and tested an automated name authority control (ANAC) tool. ANAC represents a component of a digital workflow management system developed in connection with the digital Lester S. Levy Collection of Sheet Music. The evaluation of ANAC followed the spirit of the Kenney et al. study that was, as they stated, "more exploratory than scientific." These ANAC evaluation results are shared with the hope of fostering constructive dialogue and discussions about the potential for semi-automated techniques or frameworks for library functions and services such as metadata creation. The DKC's research agenda emphasizes the development of tools that combine automated processes and human intervention, with the overall goal of involving humans at higher levels of analysis and decision-making. Others have looked at issues regarding the automated generation of metadata. A session at the 2003 Joint Conference on Digital Libraries was devoted to automatic metadata creation, and a session at the 2004 conference addressed automated name disambiguation. Commercial vendors such as OCLC, Marcive, and LTI have long used automated techniques for matching names to Library of Congress authority records. We began developing ANAC as a component of a larger suite of open source tools to support workflow management for digital projects. This article describes the goals for the ANAC tool, provides an overview of the metadata records used for testing, describes the architecture for ANAC, and concludes with discussions of the methodology and evaluation of the experiment comparing human cataloging and ANAC-generated results.

    Abstract
    This paper deals with the problem of modeling Web information resources using expert knowledge and personalized user information for improved Web searching capabilities. We propose a "Web information space" model, which is composed of Web-based information resources (HTML/XML [Hypertext Markup Language/Extensible Markup Language] documents an the Web), expert advice repositories (domain-expert-specified metadata for information resources), and personalized information about users (captured as user profiles that indicate users' preferences about experts as well as users' knowledge about topics). Expert advice, the heart of the Web information space model, is specified using topics and relationships among topics (called metalinks), along the lines of the recently proposed topic maps. Topics and metalinks constitute metadata that describe the contents of the underlying HTML/XML Web resources. The metadata specification process is semiautomated, and it exploits XML DTDs (Document Type Definition) to allow domain-expert guided mapping of DTD elements to topics and metalinks. The expert advice is stored in an object-relational database management system (DBMS). To demonstrate the practicality and usability of the proposed Web information space model, we created a prototype expert advice repository of more than one million topics/metalinks for DBLP (Database and Logic Programming) Bibliography data set. We also present a query interface that provides sophisticated querying fa cilities for DBLP Bibliography resources using the expert advice repository.

    Abstract
    Contemporary retrieval systems, which search across collections, usually ignore collection-level metadata. Alternative approaches, exploiting collection-level information, will require an understanding of the various kinds of relationships that can obtain between collection-level and item-level metadata. This paper outlines the problem and describes a project that is developing a logic-based framework for classifying collection/item metadata relationships. This framework will support (i) metadata specification developers defining metadata elements, (ii) metadata creators describing objects, and (iii) system designers implementing systems that take advantage of collection-level metadata. We present three examples of collection/item metadata relationship categories, attribute/value-propagation, value-propagation, and value-constraint and show that even in these simple cases a precise formulation requires modal notions in addition to first-order logic. These formulations are related to recent work in information retrieval and ontology evaluation.

    Abstract
    This paper describes the information properties of museum specimen labels and machine learning tools to automatically extract Darwin Core (DwC) and other metadata from these labels processed through Optical Character Recognition (OCR). The DwC is a metadata profile describing the core set of access points for search and retrieval of natural history collections and observation databases. Using the HERBIS Learning System (HLS) we extract 74 independent elements from these labels. The automated text extraction tools are provided as a web service so that users can reference digital images of specimens and receive back an extended Darwin Core XML representation of the content of the label. This automated extraction task is made more difficult by the high variability of museum label formats, OCR errors and the open class nature of some elements. In this paper we introduce our overall system architecture, and variability robust solutions including, the application of Hidden Markov and Naïve Bayes machine learning models, data cleaning, use of field element identifiers, and specialist learning models. The techniques developed here could be adapted to any metadata extraction situation with noisy text and weakly ordered elements.

    Abstract
    This paper examines the reasons why existing management practices designed to cope with paper-based data objects appear to be inadequate for managing digital data objects (DDOs). The research described suggests the need for a reassessment of the way we view long-term access to DDOs. There is a need for a shift in emphasis which embraces the fluid nature of such objects and addresses the multifaceted issues involved in achieving such access. It would appear from the findings of this research that a conceptual framework needs to be developed which addresses a range of elements. The research achieved this by examining the issues facing stakeholders involved in this field; examining the need for and structure of a new generic conceptual framework, the super-metadata framework; identifying and discussing the issues central to the development of such a framework; and justifying the feasibility through the creation of an interactive cost model and stakeholder evaluation. The wider conceptual justification for such a framework is discussed and this involves an examination of the "public good" argument for the long-term retention of DDOs and the importance of selection in the management process. The paper concludes by considering the benefits to practitioners and the role they might play in testing the feasibility of such a framework. The paper also suggests possible avenues researchers may wish to consider to develop further the management of this field.

    Abstract
    Management of rights in electronic resources on the Internet is a complex issue. this can be considered almost universal knowledge, as paraphrases of this statement can be found in many discussions on this subject. This being the case, it is not surprising that a definition, operational solution to the problem has yet to be found. In one of the world's leading metadata initiatives, the Dublin Core Metadata Initiative, discussions on this topic over several years have failed to reach a conclusion. Some people think the issue is simply too complex to handle, others that the provision of simple shortcuts to more detailed information should be sufficient. It could be argued that a solution to the issue is in fact out of scope for the Dublin Core element set, in so far as it aims only to establish a core set of descriptive metadata for resource discovery

    Abstract
    Maintaining a library of digital objects of necessaryy requires maintaining metadata about those objects. The metadata necessary for successful management and use of digital objeets is both more extensive than and different from the metadata used for managing collections of printed works and other physical materials. While a library may record descriptive metadata regarding a book in its collection, the book will not dissolve into a series of unconnected pages if the library fails to record structural metadata regarding the book's organization, nor will scholars be unable to evaluate the book's worth if the library fails to note that the book was produced using a Ryobi offset press. The Same cannot be said for a digital version of the saure book. Without structural metadata, the page image or text files comprising the digital work are of little use, and without technical metadata regarding the digitization process, scholars may be unsure of how accurate a reflection of the original the digital version provides. For internal management purposes, a library must have access to appropriate technical metadata in order to periodically refresh and migrate the data, ensuring the durability of valuable resources.

    Abstract
    The University of Sydney Library's repository contains research outputs primarily comprising traditional publication types. Many academics manage data collections within databases and spreadsheets using metadata dissimilar to the repository's Dublin Core schema. During 2007 and 2008 the author explored issues surrounding submission of a small range of research data collections and associated metadata. Native metadata structures were analysed and mapped to DC and scripts translated, packaged and transferred collections. This paper discusses metadata management and repository service levels and sustainability. It describes the Library's approach to defining service requirements and includes discussion of various metadata management options. It also describes related activities within the University of Sydney to develop eResearch services and to harmonise the roles and relationships of eResearch support service providers.

    Abstract
    "Libraries: Tools for Education and Development" war das Motto der 70. IFLA-Generalkonferenz, dem Weltkongress Bibliothek und Information, der vom 22.-27. August 2004 in Buenos Aires, Argentinien, und damit erstmals in Lateinamerika stattfand. Rund 3.000 Teilnehmerinnen und Teilnehmer, davon ein Drittel aus spanischsprachigen Ländern, allein 600 aus Argentinien, besuchten die von der IFLA und dem nationalen Organisationskomitee gut organisierte Tagung mit mehr als 200 Sitzungen und Veranstaltungen. Aus Deutschland waren laut Teilnehmerverzeichnis leider nur 45 Kolleginnen und Kollegen angereist, womit ihre Zahl wieder auf das Niveau von Boston gesunken ist. Erfreulicherweise gab es nunmehr bereits im dritten Jahr eine deutschsprachige Ausgabe des IFLA-Express. Auch in diesem Jahr soll hier über die Veranstaltungen der Division IV Bibliographic Control berichtet werden. Die Arbeit der Division mit ihren Sektionen Bibliography, Cataloguing, Classification and Indexing sowie der neuen Sektion Knowledge Management bildet einen der Schwerpunkte der IFLA-Arbeit, die dabei erzielten konkreten Ergebnisse und Empfehlungen haben maßgeblichen Einfluss auf die tägliche Arbeit der Bibliothekarinnen und Bibliothekare. Erstmals wird auch ausführlich über die Arbeit der Core Activities ICABS und UNIMARC und der Information Technology Section berichtet.
    Content
    Knowledge Management Section (Sektion Wissensmanagement) Ziel der neuen Sektion ist es, die Entwicklung und Implementierung des Wissensmanagements in Bibliotheken und Informationszentren zu fördern. Die Sektion will dafür eine internationale Plattform für die professionelle Kommunikation bieten und damit das Thema bekannter und allgemein verständlicher machen. Auf diese Weise soll seine Bedeutung auch für Bibliotheken und die mit ihm arbeitenden Einrichtungen herausgestellt werden. IFLA-CDNL Alliance for Bibliographic Standards (ICABS) Ein Jahr nach ihrer Gründung in Berlin hat die IFLA Core Activity "IFLA-CDNL Alliance for Bibliographic Standards (ICABS)" in Buenos Aires zum ersten Mal das Spektrum ihrer Arbeitsfelder einem großen Fachpublikum vorgestellt. Die IFLA Core Activity UNIMARC, einer der Partner der Allianz, hatte am Donnerstagvormittag zu einer Veranstaltung unter dem Titel "The holdings record as a bibliographic control tool" geladen. Am Nachmittag des selben Tages fand unter dem Titel "The new IFLA-CDNL Alliance for Bibliographic Standards - umbrella for multifaceted activities: strategies and practical ways to improve international coordination" die umfassende ICABS-Veranstaltung statt, die von der Generaldirektorin Der Deutschen Bibliothek, Dr. Elisabeth Niggemann, moderiert wurde. Nachdem die Vorsitzende des Advisory Board in ihrem Vortrag auf die Entstehungsgeschichte der Allianz eingegangen war, gab sie einen kurzen Oberblick über die Organisation und die Arbeit von ICABS als Dach der vielfältigen Aktivitäten im Bereich bibliographischer Standards. Vertreter aller in ICABS zusammengeschlossener Bibliotheken stellten im Anschluss daran ihre Arbeitsbereiche und -ergebnisse vor.
