    Abstract
    Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

    Abstract
    Der Aufbau der Europäischen Digitalen Bibliothek wurde im Herbst 2007 auf soliden Grund gestellt: Mit der European Digital Library Foundation steht eine geschäftsfähige Organisation als Trägerin der Europäischen Digitalen Bibliothek zur Verfügung. Sie fungiert zunächst als Steuerungsgremium für das EU-finanzierte Projekt EDLnet und übernimmt sukzessive die Aufgaben, die für den Aufbau und die Weiterentwicklung der Europäischen Digitalen Bibliothek notwendig sind. Die Gründungsmitglieder sind zehn europäische Dachorganisationen aus den Bereichen Bibliothek, Archiv, audiovisuelle Sammlungen und Museen. Vorstandsmitglieder sind die Vorsitzende Elisabeth Niggemann (CENL) die Vize-Vorsitzende Martine de Boisdeffre (EURBICA), der Schatzmeister Edwin van Huis (FIAT) sowie Wim van Drimmelen, der Generaldirektor der Koninklijke Bibliotheek, der Nationalbibliothek der Niederlande, welche die Europäische Digitale Bibliothek hostet. Der Prototyp für die Europäische Digitale Bibliothek wird im Rahmen des EDLnet-Projekts entwickelt. Die erste Version des Prototyps wurde auf der internationalen Konferenz »One more step towards the European Digital Library« vorgestellt, die am 31. Januar und 1. Februar 2008 in der Deutschen Nationalbibliothek (DNB) in Frankfurt am Main stattfand. Die endgültige Version des Prototyps wird im November 2008 von der EU-Kommissarin für Informationsgesellschaft und Medien, Viviane Reding, in Paris vorgestellt werden. Dieser Prototyp wird direkten Zugang zu mindestens zwei Mio. digitalisierten Büchern, Fotografien, Karten, Tonaufzeichnungen, Filmaufnahmen und Archivalien aus Bibliotheken, Archiven, audiovisuellen Sammlungen und Museen Europas bieten.

    Abstract
    KoT (Kinds of Tags) is an ongoing joint collaborative research effort with many participants worldwide, including the University of Minho, UKOLN, the University of Bologna, the Université Libre de Bruxelles and La Universidad Carlos III de Madrid. It is focused on the analysis of tags that are in common use in the practice of social tagging, with the aim of discovering how easily tags can be 'normalised' for interoperability with standard metadata environments such as the DC Metadata Terms.

    Abstract
    In this paper the following problem is discussed: Which possibilities exist to integrate localized knowledge into knowledge structures like classification systems or other documentary languages for the design of OPACs and information systems? It is proposed to combine a de-localized classificatory structure - best describes as 'ontological spine' - with multilingual semantic networks. Each of these networks should represent the respective localized knowledge along an extended set of typed semantic relations serving as entry points vocabulary as well as a semantic basis for navigational purposes within the localized knowledge context. The spine should enable a link between well-known and not well-known knowledge structures.

    Abstract
    In this presentation, we therefore focus on a solution for providing uniform access to Digital Libraries and other online services. In order to enable uniform query access to heterogeneous sources, we must provide metadata interoperability in a way that a query language - in this case SPARQL - can cope with the incompatibility of the metadata in various sources without changing their already existing information models.

    Abstract
    The paper reports about results on the GESIS-IZ project "Competence Center Modeling and Treatment of Semantic Heterogeneity" (KoMoHe). KoMoHe supervised a terminology mapping effort, in which 'cross-concordances' between major controlled vocabularies were organized, created and managed. In this paper we describe the establishment and implementation of crossconcordances for search in a digital library (DL).

    Abstract
    XML will have a profound impact on the way data is exchanged on the Internet. An important feature of this language is the separation of content from presentation, which makes it easier to select and/or reformat the data. However, due to the likelihood of numerous industry and domain specific DTDs, those who wish to integrate information will still be faced with the problem of semantic interoperability. In this paper we discuss why this problem is not solved by XML, and then discuss why the Resource Description Framework is only a partial solution. We then present the SHOE language, which we feel has many of the features necessary to enable a semantic web, and describe an existing set of tools that make it easy to use the language.

    Abstract
    A case study in compatibility and heterogeneity of knowledge organization (KO) systems and processes is presented. It is based in the experience of the author in the field of information for consumer protection, a good example of the emerging transdisciplinary applied social sciences. The activities and knowledge organization problems and solutions of the Aragonian Consumers' Information and Documentation Centre are described and analyzed. Six assertions can be concluded: a) heterogeneity and compatibility are certainly an inherent problem in knowledge organization and also in practical domains; b) knowledge organization is also a social task, not only a lögical one; c) knowledge organization is affected by economical and efficiency considerations; d) knowledge organization is at the heart of Knowledge Management; e) identifying and maintaining the focus in interdisciplinary fields is a must; f the different knowledge organization tools of a institution must be considered as an integrated system, pursuing a unifying model.

    Abstract
    The CACAO Project (Cross-language Access to Catalogues and Online Libraries) has been designed to implement natural language processing and cross-language information retrieval techniques to provide cross-language access to information in libraries, a critical issue in the linguistically diverse European Union. This project report addresses two metadata-related challenges for the library community in this context: "false friends" (identical words having different meanings in different languages) and term ambiguity. The possible solutions involve enriching the metadata with attributes specifying language or the source authority file, or associating potential search terms to classes in a classification system. The European Library will evaluate an early implementation of this work in late 2008.

    Abstract
    Purpose: To develop a prototype middleware framework between different terminology resources in order to provide a subject cross-browsing service for library portal systems. Design/methodology/approach: Nine terminology experts were interviewed to collect appropriate knowledge to support the development of a theoretical framework for the research. Based on this, a simplified software-based prototype system was constructed incorporating the knowledge acquired. The prototype involved mappings between the computer science schedule of the Dewey Decimal Classification (which acted as a spine) and two controlled vocabularies UKAT and ACM Computing Classification. Subsequently, six further experts in the field were invited to evaluate the prototype system and provide feedback to improve the framework. Findings: The major findings showed that given the large variety of terminology resources distributed on the web, the proposed middleware service is essential to integrate technically and semantically the different terminology resources in order to facilitate subject cross-browsing. A set of recommendations are also made outlining the important approaches and features that support such a cross browsing middleware service.

    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.

    Content
    "When dealing with a large-scale and widely-used knowledge organization system like the Dewey Decimal Classification, we often tend to focus solely on the organization aspect, which is closely intertwined with editorial work. This is perfectly understandable, since developing and updating the DDC, keeping up with current scientific developments, spotting new trends in both scholarly communication and popular publishing, and figuring out how to fit those patterns into the structure of the scheme are as intriguing as they are challenging. From the organization perspective, the intended user of the scheme is mainly the classifier. Dewey acts very much as a number-building engine, providing richly documented concepts to help with classification decisions. Since the Middle Ages, quasi-religious battles have been fought over the "valid" arrangement of places according to specific views of the world, as parodied by Jorge Luis Borges and others. Organizing knowledge has always been primarily an ontological activity; it is about putting the world into the classification. However, there is another side to this coin--the discovery side. While the hierarchical organization of the DDC establishes a default set of places and neighborhoods that is also visible in the physical manifestation of library shelves, this is just one set of relationships in the DDC. A KOS (Knowledge Organization System) becomes powerful by expressing those other relationships in a manner that not only collocates items in a physical place but in a knowledge space, and exposes those other relationships in ways beneficial and congenial to the unique perspective of an information seeker.
    What are those "other" relationships that Dewey possesses and that seem so important to surface? Firstly, there is the relationship of concepts to resources. Dewey has been used for a long time, and over 200,000 numbers are assigned to information resources each year and added to WorldCat by the Library of Congress and the German National Library alone. Secondly, we have relationships between concepts in the scheme itself. Dewey provides a rich set of non-hierarchical relations, indicating other relevant and related subjects across disciplinary boundaries. Thirdly, perhaps most importantly, there is the relationship between the same concepts across different languages. Dewey has been translated extensively, and current versions are available in French, German, Hebrew, Italian, Spanish, and Vietnamese. Briefer representations of the top-three levels (the DDC Summaries) are available in several languages in the DeweyBrowser. This multilingual nature of the scheme allows searchers to access a broader range of resources or to switch the language of--and thus localize--subject metadata seamlessly. MelvilClass, a Dewey front-end developed by the German National Library for the German translation, could be used as a common interface to the DDC in any language, as it is built upon the standard DDC data format. It is not hard to give an example of the basic terminology of a class pulled together in a multilingual way: <class/794.8> a skos:Concept ; skos:notation "794.8"^^ddc:notation ; skos:prefLabel "Computer games"@en ; skos:prefLabel "Computerspiele"@de ; skos:prefLabel "Jeux sur ordinateur"@fr ; skos:prefLabel "Juegos por computador"@es .
    Expressed in such manner, the Dewey number provides a language-independent representation of a Dewey concept, accompanied by language-dependent assertions about the concept. This information, identified by a URI, can be easily consumed by semantic web agents and used in various metadata scenarios. Fourthly, as we have seen, it is important to play well with others, i.e., establishing and maintaining relationships to other KOS and making the scheme available in different formats. As noted in the Dewey blog post "Tags and Dewey," since no single scheme is ever going to be the be-all, end-all solution for knowledge discovery, DDC concepts have been extensively mapped to other vocabularies and taxonomies, sometimes bridging them and acting as a backbone, sometimes using them as additional access vocabulary to be able to do more work "behind the scenes." To enable other applications and schemes to make use of those relationships, the full Dewey database is available in XML format; RDF-based formats and a web service are forthcoming. Pulling those relationships together under a common surface will be the next challenge going forward. In the semantic web community the concept of Linked Data (http://en.wikipedia.org/wiki/Linked_Data) currently receives some attention, with its emphasis on exposing and connecting data using technologies like URIs, HTTP and RDF to improve information discovery on the web. With its focus on relationships and discovery, it seems that Dewey will be well prepared to become part of this big linked data set. Now it is about putting the classification back into the world!"

    Abstract
    Smart applications behave intelligently because they understand at least partially the context where they operate. To do this, they need not only a formal domain model but also formal descriptions of the data they process and their own operational behaviour. Interoperability of smart applications is based on formalised definitions of all their data and processes. This paper studies the semantic interoperability of data in the case of eLearning and describes an experiment and its assessment. New content is imported into a knowledge-based learning environment without real updates of the original domain model, which is encoded as a knowledge base of conceptual graphs. A component called mediator enables the import by assigning dummy metadata annotations for the imported items. However, some functionality of the original system is lost, when processing the imported content, due to the lack of proper metadata annotation which cannot be associated fully automatically. So the paper presents an interoperability scenario when appropriate content items are viewed from the perspective of the original world and can be (partially) reused there.

    Classification and Indexing Section (Sektion Klassifikation und Indexierung) Deutsches Mitglied im Ständigen Ausschuss der Sektion: Yvonne Jahns (2005-2009; Deutsche Nationalbibliothek) Die Sektion, die sich als Forum für den internationalen Austausch über Methoden der Inhaltserschließung und die Bedeutung des sachlichen Zugangs zu Dokumenten und Wissen versteht, wartete in Quebec mit einem interessanten Vortragprogramm auf. Drei Präsentationen näherten sich dem Thema "Classification and indexing without language borders" von unterschiedlichen Seiten. Anila Angjeli von der Bibliotheque nationale de France (BnF) präsentierte Arbeiten aus dem Projekt STITCH", das sich mit semantischen Suchen in unterschiedlich erschlossenen Beständen von Kulturerbeinstitutionen beschäftigt. Die verwendeten Thesauri und Klassifikationen wurden mittels SKOS in ein vergleichbares Format überführt und stehen so als Semantic-Web-Anwendung zur Recherche bereit. Die Funktionsweise erläuterte Anila Angjeli sehr bildreich durch Beispiel-suchen nach mittelalterlichen Handschriften der BnF und der Königlichen Bibliothek der Niederlande. Vivien Petras vom GESIS Informationszentrum Sozialwissenschaften, Bonn, sprach über die Vielzahl der intellektuell erstellten Crosskonkordanzen zwischen Thesauri in den Sozialwissenschaften. Sie stellte dabei die Evaluierung der KOMOHE-Projektergebnisse vor und konnte die Verbesserung der Suchergebnisse anschaulich machen, die man durch Hinzuziehen der Konkordanzen in der Recherche über heterogen erschlossene Bestände erreicht. Schließlich präsentierte Michael Kreyche von der Kent State University, Ohio/USA, seinen eindrucksvollen jahrelangen Einsatz für die Zugänglichkeit englisch-spanischer Schlagwörter. Im Projekt Icsh-es.org gelang es, viele Vorarbeiten von amerikanischen und spanischen Bibliotheken zusammenzutragen, um eine Datenbank spanischer Entsprechungen der Library of Congress Subject Headings aufzubauen. Diese soll Indexierern helfen und natürlich den vielen spanisch-sprachigen Bibliotheksbenutzern in den USA zugute kommen. Spanisch ist nicht nur eine der meistgesprochenen Sprachen der Welt, sondern aufgrund der zahlreichen Einwanderer in die USA für die Bibliotheksarbeit von großer Wichtigkeit.
    Am Rande des Weltkongresses fanden zum wiederholten Male DDC- und UDC-Anwendertreffen statt. Für alle an der DDC Interessierten ist das Programm im Dewey-Blog vom 19. August 2008 zu finden. Besonders interessant ist der neue OCLC-Service namens "Classify", der als Webservice aufgesetzt werden soll und dem Anwender aus WorldCat-Daten zuverlässige Notationen herausfiltert - eine gute Hilfe beim Klassifizieren (zur Fremddatenübernahme) und beim Orientieren in einer internationalen DDC-Umgebung. Hingewiesen sei noch auf die anlässlich des Kongresses frei geschaltete Suchoberfläche der ortsansässigen Bibliotheque de l'Universite Lava Ariane 2.0 ist eine intuitive und einfach zu bedienende Katalogsuchmaschine, die insbesondere die Schlagwörter des Repertoire de vedettes-matiere (RVM) zur Navigation benutzt. RVM ist die französischsprachige Schlagwortnormdatei Kanadas, in enger Anlehnung an die LCSH entstanden und heute in enger Kooperation zu den Rameau der BnF gepflegt und von Library and Archives Canada als der französische Indexierungsstandard Kanadas betrachtet. Für die Pflege ist die Laval-Universitätsbibliothek verantwortlich. Eben erschien der neue "Guide pratique du RVM" - ein schwergewichtiger Führer durch die Schlagwortwelt und ein kleines Indexierungsregelwerk.

    Abstract
    Knowledge organization systems (KOS), like thesauri and other controlled vocabularies, are used to provide subject access to information systems across the web. Due to the heterogeneity of these systems, mapping between vocabularies becomes crucial for retrieving relevant information. However, mapping thesauri is a laborious task, and thus big efforts are being made to automate the mapping process. This paper examines two mapping approaches involving the agricultural thesaurus AGROVOC, one machine-created and one human created. We are addressing the basic question "What are the pros and cons of human and automatic mapping and how can they complement each other?" By pointing out the difficulties in specific cases or groups of cases and grouping the sample into simple and difficult types of mappings, we show the limitations of current automatic methods and come up with some basic recommendations on what approach to use when.
