    Abstract
    This article presents an exploratory study of Blobgects, an experimental interface for an online museum catalog that enables social tagging and blogging activity around a set of cultural heritage objects held by a preeminent museum of anthropology and archaeology. This study attempts to understand not just whether social tagging and commenting about these objects is useful but rather whose tags and voices matter in presenting different expert perspectives around digital museum objects. Based on an empirical comparison between two different user groups (Canadian Inuit high-school students and museum studies students in the United States), we found that merely adding the ability to tag and comment to the museum's catalog does not sufficiently allow users to learn about or engage with the objects represented by catalog entries. Rather, the specialist language of the catalog provides too little contextualization for users to enter into the sort of dialog that proponents of Web 2.0 technologies promise. Overall, we propose a more nuanced application of Web 2.0 technologies within museums - one which provides a contextual basis that gives users a starting point for engagement and permits users to make sense of objects in relation to their own needs, uses, and understandings.

    Abstract
    The concept for the German Digital Libraries Program is imbedded in the Information Infrastructure Program of the German Federal Government for the years 1996-2000 which has been explicated in the Program Paper entitled "Information as Raw Material for Innovation".3 The Program Paper was published 1996 by the Federal Ministry for Education, Research, and Technology. The actual grants program "Global Info" was initiated by the Information and Communication Commission of the Joint Learned Societies to further technological advancement in enabling all researchers in Germany direct access to literature, research results, and other relevant information. This Commission was founded by four of the learned societies in 1995, and it has sponsored a series of workshops to increase awareness of leading edge technology and innovations in accessing electronic information sources. Now, nine of the leading research-level learned societies -- often those with umbrella responsibilities for other learned societies in their field -- are members of the Information and Communication Commission and represent the mathematicians, physicists, computer scientists, chemists, educational researchers, sociologists, psychologists, biologists and information technologists in the German Association of Engineers. (The German professional librarian societies are not members, as such, of this Commission, but are represented through delegates from libraries in the learned societies and in the future, hopefully, also by the German Association of Documentalists or through the cooperation between the documentalist and librarian professional societies.) The Federal Ministry earmarked 60 Million German Marks for projects within the framework of the German Digital Libraries Program in two phases over the next six years. The scope for the German Digital Libraries Program was announced in a press release in April 1997,4 and the first call for preliminary projects and expressions of interest in participation ended in July 1997. The Consortium members were suggested by the Information and Communication Commission of the Learned Societies (IuK Kommission), by key scientific research funding agencies in the German government, and by the publishers themselves. The first official meeting of the participants took place on December 1, 1997, at the Deutsche Bibliothek, located in the renowned center of German book trade, Frankfurt, thus documenting the active role and participation of libraries and publishers. In contrast to the Digital Libraries Project of the National Science Foundation in the United States, the German Digital Libraries project is based on furthering cooperation with universities, scientific publishing houses (including various international publishers), book dealers, and special subject information centers, as well as academic and research libraries. The goals of the German Digital Libraries Project are to achieve: 1) efficient access to world wide information; 2) directly from the scientist's desktop; 3) while providing the organization for and stimulating fundamental structural changes in the information and communication process of the scientific community.

    Abstract
    The Internet would not be very useful if communication were limited to textual exchanges between speakers of English located in the United States. Rather, its value lies in its ability to enable people from multiple nations, speaking multiple languages, to employ multiple media in interacting with each other. While computer networks broke through national boundaries long ago, they remain much more effective for textual communication than for exchanges of sound, images, or mixed media -- and more effective for communication in English than for exchanges in most other languages, much less interactions involving multiple languages. Supporting searching and display in multiple languages is an increasingly important issue for all digital libraries accessible on the Internet. Even if a digital library contains materials in only one language, the content needs to be searchable and displayable on computers in countries speaking other languages. We need to exchange data between digital libraries, whether in a single language or in multiple languages. Data exchanges may be large batch updates or interactive hyperlinks. In any of these cases, character sets must be represented in a consistent manner if exchanges are to succeed. Issues of interoperability, portability, and data exchange related to multi-lingual character sets have received surprisingly little attention in the digital library community or in discussions of standards for information infrastructure, except in Europe. The landmark collection of papers on Standards Policy for Information Infrastructure, for example, contains no discussion of multi-lingual issues except for a passing reference to the Unicode standard. The goal of this short essay is to draw attention to the multi-lingual issues involved in designing digital libraries accessible on the Internet. Many of the multi-lingual design issues parallel those of multi-media digital libraries, a topic more familiar to most readers of D-Lib Magazine. This essay draws examples from multi-media DLs to illustrate some of the urgent design challenges in creating a globally distributed network serving people who speak many languages other than English. First we introduce some general issues of medium, culture, and language, then discuss the design challenges in the transition from local to global systems, lastly addressing technical matters. The technical issues involve the choice of character sets to represent languages, similar to the choices made in representing images or sound. However, the scale of the language problem is far greater. Standards for multi-media representation are being adopted fairly rapidly, in parallel with the availability of multi-media content in electronic form. By contrast, we have hundreds (and sometimes thousands) of years worth of textual materials in hundreds of languages, created long before data encoding standards existed. Textual content from past and present is being encoded in language and application-specific representations that are difficult to exchange without losing data -- if they exchange at all. We illustrate the multi-language DL challenge with examples drawn from the research library community, which typically handles collections of materials in 400 or so languages. These are problems faced not only by developers of digital libraries, but by those who develop and manage any communication technology that crosses national or linguistic boundaries.

    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    The Deutsche Forschungsgemeinschaft (DFG) is the central public funding organization for academic research in Germany. It is thus comparable to a research council or a national research foundation. According to its statutes, DFG's mandate is to serve science and the arts in all fields by supporting research projects carried out at universities and public research institutions in Germany, to promote cooperation between researchers, and to forge and support links between German academic science, industry and partners in foreign countries. In the fulfillment of its tasks, the DFG pays special attention to the education and support of young scientists and scholars. DFG's mandate and operations follow the principle of territoriality. This means that its funding activities are restricted, with very few exceptions, to individuals and institutions with permanent addresses in Germany. Fellowships are granted for work in other countries, but most fellowship programs are restricted to German citizens, with a few exceptions for permanent residents of Germany holding foreign passports.

    Abstract
    Digital libraries have become commodity in the current world of Internet. More and more information is produced, and more and more non-digital information is being rendered available. The new, more user friendly, community-oriented technologies used throughout the Internet are raising the bar of expectations. Digital libraries cannot stand still with their technologies; if not for the sake of handling rapidly growing amount and diversity of information, they must provide for better user experience matching and overgrowing standards set by the industry. The next generation of digital libraries combine technological solutions, such as P2P, SOA, or Grid, with recent research on semantics and social networks. These solutions are put into practice to answer a variety of requirements imposed on digital libraries.

    Abstract
    There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This paper discusses a matching function for compound descriptors, or multi-concept subject headings, that does not rely an exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based an a measure of semantic closeness between terms, which has the potential to help with recall problems. The work reported is part of the ongoing FACET project in collaboration with the National Museum of Science and Industry and its collections database. The architecture of the prototype system and its Interface are outlined. The matching problem for compound descriptors is reviewed and the FACET implementation described. Results are discussed from scenarios using the faceted Getty Art and Architecture Thesaurus. We argue that automatic traversal of thesaurus relationships can augment the user's browsing possibilities. The techniques can be applied both to unstructured multi-concept subject headings and potentially to more syntactically structured strings. The notion of a focus term is used by the matching function to model AAT modified descriptors (noun phrases). The relevance of the approach to precoordinated indexing and matching faceted strings is discussed.

    Abstract
    A primary goal of the NSDL Materials Digital Library (MatDL) is to bring materials science research and education closer together. MatDL is exploring the various roles digital libraries can serve in the materials science community including: 1) supporting a virtual lab, 2) developing markup language applications, and 3) building tools for metadata capture. MatDL is being integrated into an MIT virtual laboratory experience. Early student self-assessment survey results expressed positive opinions of the potential value of MatDL in supporting a virtual lab and in accomplishing additional educational objectives. A separate survey suggested that the effectiveness of a virtual lab may approach that of a physical lab on some laboratory learning objectives. MatDL is collaboratively developing a materials property grapher (KSU and MIT) and a submission tool (KSU and U-M). MatML is an extensible markup language for exchanging materials information developed by materials data experts in industry, government, standards organizations, and professional societies. The web-based MatML grapher allows students to compare selected materials properties across approximately 80 MatML-tagged materials. The MatML grapher adds value in this educational context by allowing students to utilize real property data to make optimal material selection decisions. The submission tool has been integrated into the regular workflow of U-M students and researchers generating nanostructure images. It prompts users for domain-specific information, automatically generating and attaching keywords and editable descriptions.

    Abstract
    Purpose - One of the unresolved problems of the global information society is ensuring the long-term accessibility of digital documents. The project kopal tackles this problem head-on: in a three-year project kopal's objective is the practical testing and implementation of a cooperatively created and operated long-term archival system for digital resources. Design/methodology/approach - The system will be implemented in accordance with international standards for long-term archiving and metadata within the Open Archival Information System (OAIS) framework. The project partners, Die Deutsche Bibliothek (DDB), Göttingen State and University Library (SUB Göttingen), IBM Deutschland GmbH and the Gesellschaft für wissenschaftliche Datenverarbeitung mbH Göttingen (GWDG), will establish a cooperatively transferable solution for cultural heritage institutions, as well as for business and industry. Findings - Within the project, the project partners DDB and SUB Göttingen are developing software for the input and access of data, which will be released under an open-source license. Research limitations/implications - Long-term preservation methods and strategies will be discussed in general in the paper. Practical implications - The project will present a stable and reusable platform for additional partners and users, especially for cultural heritage organisations. Originality/value - The solution is based on Digital Information and Archiving System (DIAS), jointly devised by IBM and the National Library of The Netherlands in The Hague, and it will be adapted to the needs of the project with several extensions. Establishing a collaborative solution for long-term preservation is a milestone in the development of systems for the long-term availability of digital objects.

    Abstract
    Service-oriented architectures, and the wider acceptance of decentralized peer-to-peer architectures enable the transition from integrated, centrally controlled systems to federated and dynamic configurable systems. The benefits for the individual service providers and users are robustness of the system, independence of central authorities and flexibility in the usage of services. This chapter provides details of the European project BRICKS, which aims at enabling integrated access to distributed resources in the Cultural Heritage domain. The target audience is broad and heterogeneous and involves cultural heritage and educational institutions, the research community, industry, and the general public. The project idea is motivated by the fact that the amount of digital information and digitized content is continuously increasing but still much effort has to be expended to discover and access it. The reasons for such a situation are heterogeneous data formats, restricted access, proprietary access interfaces, etc. Typical usage scenarios are integrated queries among several knowledge resource, e.g. to discover all Italian artifacts from the Renaissance in European museums. Another example is to follow the life cycle of historic documents, whose physical copies are distributed all over Europe. A standard method for integrated access is to place all available content and metadata in a central place. Unfortunately, such a solution requires a quite powerful and costly infrastructure if the volume of data is large. Considerations of cost optimization are highly important for Cultural Heritage institutions, especially if they are funded from public money. Therefore, better usage of the existing resources, i.e. a decentralized/P2P approach promises to deliver a significantly less costly system,and does not mean sacrificing too much on the performance side.

    Abstract
    There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This demonstration of a research prototype illustrates a matching function for compound descriptors, or multi-concept subject headings, that does not rely on exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based on a measure of semantic closeness between terms.The work is part of the EPSRC funded FACET project in collaboration with the UK National Museum of Science and Industry (NMSI) which includes the National Railway Museum. An export of NMSI's Collections Database is used as the dataset for the research. The J. Paul Getty Trust's Art and Architecture Thesaurus (AAT) is the main thesaurus in the project. The AAT is a widely used thesaurus (over 120,000 terms). Descriptors are organised in 7 facets representing separate conceptual classes of terms.The FACET application is a multi tiered architecture accessing a SQL Server database, with an OLE DB connection. The thesauri are stored as relational tables in the Server's database. However, a key component of the system is a parallel representation of the underlying semantic network as an in-memory structure of thesaurus concepts (corresponding to preferred terms). The structure models the hierarchical and associative interrelationships of thesaurus concepts via weighted poly-hierarchical links. Its primary purpose is real-time semantic expansion of query terms, achieved by a spreading activation semantic closeness algorithm. Queries with associated results are stored persistently using XML format data. A Visual Basic interface combines a thesaurus browser and an initial term search facility that takes into account equivalence relationships. Terms are dragged to a direct manipulation Query Builder which maintains the facet structure.

    Abstract
    The paper will explore the issues surrounding the development of an evaluation framework for a supranational digital library system, as seen through the TEL (The European Library) project. It will describe work an the project to date, and seek to establish what are the key drivers, priorities and barriers encountered, in developing such a framework. TEL is being funded by the EU as an Accompanying Measure in the IST program. Its main focus of is an consensus building, and also includes preparatory technical work to develop testbeds, which will gauge to what extent interoperability is achievable. In order for TEL to take its place as a major Information Society initiative of the EU, it needs to be closely attuned to the needs, expectations and realities of its user communities, which comprise the citizens of the project's national partners. To this end the evaluation framework described in this paper, is being developed by establishing the users' viewpoints and priorities in relation to the key project themes. A summary of the issues to be used in the baseline, and to be expanded upon in the paper, follows: - Establishing the differing contexts of the national library partners, and the differing national priorities which will impact an TEL - Exploring the differing expectations relating to building and using the hybrid library - Exploring the differing expectations relating to TEL. TEL needs to add value - what does this mean in each partner state, and for the individuals within them? 1. Introduction to TEL TEL (The European Library) is a thirty month project, funded by the European Commission as part of its Fifth Framework Programme for research. It aims to set up a co-operative framework for access to the major national, mainly digital, collections in European national libraries. TEL is funded as an Accompanying Measure, designed to support the work of the IST (Information Society Technologies) Programme an the development of access to cultural and scientific knowledge. TEL will stop short of becoming a live service during the lifetime of the project, and is focused an ensuring co-operative and concerted approaches to technical and business issues associated with large-scale content development. It will lay the policy and technical groundwork towards a pan European digital library based an distributed digital collections, and providing seamless access to the digital resources of major European national libraries. It began in February, 2001, and has eight national library partners: Finland, Germany, Italy, the Netherlands, Portugal, Slovenia, Switzerland and the United Kingdom. It is also seeking to encourage the participation of all European national libraries in due course.

    Abstract
    The main motivation of this chapter was to gather existing requirements and solutions, and to present a generic architectural design of semantic digital libraries. This design is meant to answer a number of requirements, such as interoperability or ability to exchange resources and solutions, and set up the foundations for the best practices in the new domain of semantic digital libraries. We start by presenting the library from different high-level perspectives, i.e., user (see Sect. 2) and metadata (see Sect. 1) perspective; this overview narrows the scope and puts emphasis on certain aspects related to the system perspective, i.e., the architecture of the actual digital library management system. We conclude by presenting the system architecture from three perspectives: top-down layered architecture (see Sect. 3), vertical architecture of core services (see Sect. 4), and stack of enabling infrastructures (see Sect. 5); based upon the observations and evaluation of the contemporary state of the art presented in the previous sections, these last three subsections will describe an in-depth model of the digital library management system.

    Abstract
    The Digital Public Library of America brings together the riches of America's libraries, archives, and museums, and makes them freely available to the world. In order to do this, DPLA has had to build elements of the national digital platform to connect to those institutions and to serve their digitized materials to audiences. In this article, we detail the construction of two critical elements of our work: the decentralized national network of "hubs," which operate in states across the country; and a version of the Hydra repository software that is tailored to the needs of our community. This technology and the organizations that make use of it serve as the foundation of the future of DPLA and other projects that seek to take advantage of the national digital platform.
