    The Metis project is developing workflow technology designed for use in digital libraries by avoiding the assumptions made by traditional workflow systems. In particular, digital libraries have highly distributed sets of stakeholders who nevertheless must work together to perform shared activities. Hence, traditional assumptions that all members of a workflow belong to the same organization, work in the same fashion, or have access to similar computing platforms are invalid. The Metis approach makes use of event-based workflows to support the distributed nature of digital library workflow and employs techniques to make the resulting technology lightweight, flexible, and integrated with the Web. We describe the conceptual framework behind the Metis approach as well as a prototype which implements the framework. The prototype represents a "proof-of-concept" of the Metis framework and approach as we show how it can both model and execute a peer review workflow drawn from a "real-world" digital library. We conclude with a discussion of future research opportunities in the area of digital library workflow and outline how Metis is being deployed to a small set of digital libraries for additional evaluation.

    To access the content of digital texts efficiently, it is necessary to provide more sophisticated access than keyword based searching. Genescene provides biomedical researchers with research findings and background relations automatically extracted from text and experimental data. These provide a more detailed overview of the information available. The extracted relations were evaluated by qualified researchers and are precise. A qualitative ongoing evaluation of the current online interface indicates that this method to search the literature is more useful and efficient than keyword based searching. View full abstract»

    G-Portal is a Web portal system providing a range of digital library services to access geospatial and georeferenced resources on the Web. Among them are the storage and query subsystems that provide a central repository of metadata resources organized under different projects. In G-Portal, all metadata resources are represented in XML (Extensible Markup Language) and they are compliant to some resource schemas defined by their creators. The resource schemas are extended versions of a basic resource schema making it easy to accommodate all kinds of metadata resources while maintaining the portability of resource data. To support queries over the geospatial and georeferenced metadata resources, a XQuery-like query language known as RQL (Resource Query Language) has been designed. We present the RQL language features and provide some experimental findings about the storage design and query evaluation strategies for RQL, queries. View full abstract»

    Conceptual browsing interfaces can help educators and learners to locate and use learning resources in educational digital libraries; in particular, resources that are aligned with nationally-recognized learning goals. Towards this end, we are developing a strand map library service, based on the maps published by the American Association for the Advancement of Science (AAAS). This service includes two public interfaces: (1) a graphical user interface for use by teachers and learners and (2) a programmatic interface that enables developers to construct conceptual browsing interfaces using dynamically generated components. We describe our iterative, rapid prototyping design methodology, and the initial round of language type components that have been implemented and evaluated. View full abstract»

    Though the Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) is becoming the de facto standard for digital libraries, some of its predecessors are still in use. Although a limited number of Dienst repositories continue to be populated, others are precariously unsupported. The Dienst Open Archive Gateway (DOG) is a gateway between the OAI-PMH and the Dienst (version 4.1) protocol. DOG allows OAI-PMH harvesters to extract metadata records (in RFC-1807 or Dublin Core) from Dienst servers. View full abstract»

  • Collections and access policies of the digital material of ten National Libraries

    Publication Year: 2003
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (168 KB)  

    We explore the digital collections of ten National Libraries and the applied access policies, when the digital material is free or restricted or the reproduction requires written permission or fees. We classify the implemented access policies according to their characteristics. We examine the differences among the implemented access policies and we generalize the solution approaches combining the varying parameters and other relevant emerging ones. The selection of the access policies is crucial for the acceptance and maintenance of the digital libraries. The success of any conventional or digital library depends on the usage of its material from the users. The usage of the material depends on the selection of the access policy. View full abstract»

    We describe a collaboration project between the Palau Community College (PCC) Library and the Belau National Museum (BNM). The project, funded by a two-year U.S. Institute of Museum and Library Services (IMLS) National Leadership Grant, enhances access to the BNM Media Collection. The Media Collection is in great demand, and the pressures of human use exacerbate an already tenuous situation for the long-term preservation of the images. While digitization is not viewed as the preservation solution, it assists the Museum to lessen the impact of human handling. By making the Media Collection more accessible through integration of the PCC Library's online catalog, a much wider audience is reached, and mishandling of the original image is significantly reduced. The PCC Website links the Library WebCollection Plus, which contains digitized images selected from the extensive photo archives, as well as digitized images of the ethnographic and other objects in the Museum's collection, including contemporary art.

    We present the project LEBONED that focuses on the integration of digital libraries and their contents into Web-based learning environments. We describe in general how the architecture of a standard learning management system has to be modified to enable the integration of digital libraries. An important part of this modification is the LEBONED metadata architecture which depicts the handling of metadata and documents imported from digital libraries. The main components of this architecture and their interrelation are presented in detail. Afterwards we show a practical application of the concepts described before: the integration of the digital library eVerlage into the learning management system Blackboard. View full abstract»

    Niche search engines offer an efficient alternative to traditional search engines when the results returned by general-purpose search engines do not provide a sufficient degree of relevance and when nontraditional search features are required. Niche search engines can take advantage of their domain of concentration to achieve higher relevance and offer enhanced features. We discuss a new digital library niche search engine, eBizSearch, dedicated to e-business and e-business documents. The ground technology for eBizSearch is CiteSeer, a special-purpose automatic indexing document digital library and search engine developed at NEC Research Institute. We present the integration of CiteSeer in the framework of eBizSearch and the process necessary to tune the whole system towards the specific area of e-business. We show how using machine learning algorithms we generate metadata to make eBizSearch Open Archives compliant. View full abstract»

    A musical piece typically has a repetitive structure. Analysis of this structure will be useful for music segmentation, indexing and thumbnailing. We present an algorithm that can automatically analyze the repetitive structure of musical signals. First, the algorithm detects the repetitions of each segment affixed length in a piece using dynamic programming. Second, the algorithm summarizes this repetition information and infers the structure based on heuristic rules. The performance of the approach is demonstrated visually using figures for qualitative evaluation, and by two structural similarity measures for quantitative evaluation. Based on the structural analysis result, a method for music thumbnailing is proposed. The preliminary results obtained using a corpus of Beatles' songs show that automatic structural analysis and thumbnailing of music are possible. View full abstract»
