  abstract: "Digital libraries (DLs) are among the most complex kinds of information systems, due in part to their intrinsic multi disciplinary nature. Nowadays DLs are built within monolithic, tightly integrated, and generally inflexible systems -- or by assembling disparate components together in an ad-hoc way, with resulting problems in interoperability and adaptability. More importantly, conceptual modeling, requirements analysis, and software engineering approaches are rarely supported, making it extremely difficult to tailor DL content and behavior to the interests, needs, and preferences of particular communities. In this paper, we address these problems. In particular, we present 5SL, a declarative language for specifying and generating domain-specific digital libraries. 5SL is based on the 5S formal theory for digital libraries and enables high-level specification of DLs in five complementary dimensions, including: the kinds of multimedia information the DL supports (Stream Model); how that information is structured and organized (Structural Model); different logical and presentational properties and operations of DL components (Spatial Model); the behavior of the DL (Scenario Model); and the different societies of actors and managers of services that act together to carry out the DL behavior (Societal Model). The practical feasibility of the approach is demonstrated by the presentation of a 5SL digital library generator for the MARIAN digital library system. "

  abstract: "Requirements gathering and conceptual modeling are essential for the customization of digital libraries (DLs), to help attend the needs of target communities. In this paper, we show how to apply the 5S (Streams, Structures, Spaces, Scenarios, and Societies) formal framework to support both tasks. The intuitive nature of the framework allows for easy and systematic requirements analysis, while its formal nature ensures the precision and correctness required for semi-automatic DL generation. Further, we show how 5S can help us define a domain-specific DL metamodel in the field of archaeology. Finally, an archaeological DL case study (from the ETANA project) yields informal and formal descriptions of two DL models (instances of the metamodel). "

  abstract: "The current demand from non-experts who wish to build digital libraries is strong worldwide. However, since DLs are complex systems, it usually takes a huge amount of effort and time to create and tailor a digital library to satisfy specific needs and requirements of target communities/societies. What is desired is a simplified modeling process and rapid generation of digital libraries. To enable this, digital libraries should be modeled with descriptive domain-specific languages [1]. In a domainspecific modeling language, the models are made up of elements representing concepts, rules, and terminology that are part of the domain world, as opposed to the code world or generic modeling languages (e.g., UML [2]). A visual modeling tool would be helpful to non-experts so they may model a digital library without knowing the theoretical foundations and the syntactical details of the descriptive language. In this demonstration, we present a domain-specific visual modeling tool, 5SGraph, aimed at modeling digital libraries. 5SGraph is based on a metamodel that describes DLs using the 5S theory [3]. The output from 5SGraph is a digital library model that is an instance of the metamodel, expressed in the 5S description language (5SL) [4]. 5SGraph presents the metamodel in a structured toolbox, and provides a top-down visual building environment for designers (see Figure 1). The visual proximity of the metamodel and instance model facilitates requirements gathering and simplifies the modeling process. Furthermore, 5SGraph maintains semantic constraints specified by the 5S metamodel and enforces these constraints over the instance model to ensure semantic consistency and correctness. 5SGraph enables component reuse to reduce the time and efforts of designers. 5SGraph also is designed to be flexible and extensible, able to accommodate and integrate several other complementary tools (e.g., to model scenarios or complex digital objects), reflecting the interdisciplinary nature of digital libraries. The tool has been tested with real users and several modeling tasks in a usability experiment [5] and its usefulness and learnability have been demonstrated."

In this article, we propose the fundamental abstractions of Streams, Structures, Spaces, Scenarios, and Societies (5S), which allow us to define digital libraries rigorously and usefully. Streams are sequences of arbitrary items used to describe both static and dynamic (e.g., video) content. Structures can be viewed as labeled directed graphs, which impose organization. Spaces are sets with operations on those sets that obey certain constraints. Scenarios consist of sequences of events or actions that modify states of a computation in order to accomplish a functional requirement. Societies are sets of entities and activities and the relationships among them. Together these abstractions provide a formal foundation to define, relate, and unify concepts---among others, of digital objects, metadata, collections, and services---required to formalize and elucidate \"digital libraries\". The applicability, versatility, and unifying power of the 5S model are demonstrated through its use in three distinct applications: building and interpretation of a DL taxonomy, informal and formal analysis of case studies of digital libraries (NDLTD and OAI), and utilization as a formal basis for a DL description language.

  abstract: "Digital Libraries are complex information systems that involve rich sets of digital objects and their respective metadata, along with multiple organizational structures and services (e.g., searching, browsing, and personalization), and are normally built having a target community of users with specific interests. Central to the success of this type of system is the quality of their services and content. In the context of DLs of scientific literature, among the many problems faced to sustain their information quality, two specific ones, related to information consistency, have taken a lot of attention from the research community: name disambiguation and lack of information to access the full-text of cataloged documents. In this paper, we examine these two problems and describe the solutions we have proposed to solve them."

  abstract: "The Networked Digital Library of Theses and Dissertations (NDLTD) is a collaborative effort of universities around the world to promote creating, archiving, distributing and accessing Electronic Theses and Dissertations (ETDs). Since its inception in 1996, over a hundred universities have joined the initiative, underscoring the importance institutions place on training their graduates in the emerging forms of digital publishing and information access. The outreach and training mission of NDLTD is an ongoing project so in this article we report on the current status of membership and support activities. Recent research has focused on creating a union database that will provide a means to search and retrieve ETDs from the combined collections of NDLTD member institutions. The Virtua system developed by VTLS will serve as the heart of this union database. In order to bridge the gap between the existing distributed institutional archives and a unified collection of ETDs, we have developed a metadata standard especially suited to ETDs - this is then used by partner sites to export their freely-available metadata using the Metadata Harvesting Protocol of the Open Archives Initiative. We also link name authority information into the metadata records to support unique identification of authors and others associated with the works. Additional research efforts include advanced search mechanisms, semantic interoperability, the design and development of multi- and cross-lingual search systems, and software modules that support the development of higher-level services to aid researchers in seeking relevant ETDs.

  abstract: "Digital libraries (DLs) have eluded definitional consensus and lack agreement on common theories and frameworks. This makes comparison of DLs extremely difficult, promotes ad-hoc development, and impedes interoperability. In this paper we propose a formal ontology for DLs that defines the fundamental concepts, relationships, and axiomatic rules that govern the DL domain, therefore providing a frame of reference for the discussion of essential concepts of DL design and construction. The ontology is an axiomatic, formal treatment of DLs, which distinguishes it from other approaches that informally define a number of architectural variants. The process of construction of the ontology was guided by 5S, a formal framework for digital libraries. To test its expressibility we have used the ontology to create a taxonomy of DL services and to reason about issues of reusability, extensibility, and composability. Some practical applications of the ontology are also described including: the definition of a digital library services taxonomy, the proposal of a modeling language for digital libraries, and the specification of quality metrics to evaluate digital libraries. We also demonstrate how to use the ontology to formally describe DL architectures and to prove some properties about them, thus helping to further validate the ontology. "
