"Die Europäische Union hat zum ersten Mal eine gemeinsame digitale Bibliothek. Auf dem Internetportal www.europeana.eu stehen seit Donnerstag fast drei Millionen Dokumente, Bücher, Gemälde,Filme und Fotografien aus europäischen Sammlungen zur Verfügung, teilte die EU-Kommission mit. Bereits in den ersten Stunden nach der Freischaltung besuchten mehr als zehn Millionen Internetnutzer die Seite, die vorübergehend zusammenbrach. Die Zahl der Server wurde daraufhin von drei auf sechs verdoppelt. "Wir hätten uns in unseren kühnsten Träumen nicht vorstellen können, dass es einen solchen Ansturm auf Europeana gibt", sagte EU-Medienkommissarin Viviane Reding in Brüssel. Bis 2010 sollen auf dem Portal zehn Millionen Objekte in allen EU-Sprachen abrufbar sein. Mehr als 1000 Archive, Museen und Bibliotheken lieferten bereits digitalisiertes Material. Die Kommission stellt zwei Millionen Euro pro Jahr für den Unterhalt der Plattform bereit. Die Kosten für die Digitalisierung tragen die Mitgliedstaaten. Bisher ist nur ein Prozent aller europäischen Kulturgüter elektronisch verfügbar. Um die angestrebte Zahl von zehn Millionen Werken bis 2010 zu erreichen, müssen die Staaten nach Schätzung der Kommission zusammen weitere 350 Millionen Euro in die Hand nehmen. Wie viel die Mitgliedstaaten bisher aufbrachten, blieb offen. Die EU will die Erforschung und Entwicklung von Technologien in dem Bereich in den kommenden zwei Jahren mit 119 Millionen Euro fördern. Die EU-Kulturminister sprachen sich dafür aus, das kulturelle Angebot im Internet weiter auszubauen und gleichzeitig ihren Kampf gegen Online-Piraterie zu verstärken. "Wir wollen legale glaubwürdige Angebote für Verbraucher schaffen", sagte die französische Ressortchefin Christine Albanel, die derzeit die Ministerrunde führt"

"Brüssel. Die erste gemeinsame Online-Bibliothek der Europäischen Union ist nach nur wenigen Stunden wegen technischer Probleme wieder abgeschaltet worden. Ein unerwarteter Besucheransturm legte das Portal www.europeana.eu lahm, sagte ein Sprecher der EU-Kommission am Freitag in Brüssel. Die 20 Millionen Klicks pro Stunde habe die Seite nicht verkraftet. "Wir waren ausgerüstet für fünf Millionen Klicks", begründete der Sprecher die Panne. Spätestens bis Mitte Dezember soll die Seite wieder zur Verfügung stehen. Zuvor müsse zusätzliche Computerkapazität im Rechenzentrum der Universität Amsterdam angemietet werden. Bereits am Donnerstagmittag war die Zahl der Server von drei auf sechs verdoppelt worden, nachdem die Seite bereits in den ersten Stunden nach der Freischaltung vorübergehend zusammengebrochen war. "Die Kosten können noch aus dem Budget der Europeana abgedeckt werden", sagte der Sprecher. Europeana macht Dokumente, Bücher, Gemälde, Filme und Fotografien aus europäischen Sammlungen kostenlos im Internet zugänglich. Bisher sind dort knapp drei Millionen Objekte eingestellt, bis 2010 sollen es zehn Millionen sein. Mehr als 1000 Archive, Museen und Bibliotheken haben bereits digitalisiertes Material geliefert. Die Kommission stellt zwei Millionen Euro pro Jahr für den Unterhalt der Plattform bereit. Die Kosten für die Digitalisierung tragen die Mitgliedstaaten."

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

- ViFas können Social Bookmarking nutzen, um neue Quellen zu erschließen (Personalknappheit). - Der Erfolg ist allerdings davon abhängig, dass eine kritische Masse an Nutzerinnen und Nutzern erreicht wird. Bei den zu erwartenden fachlich spezialisierten Nutzerinnen und Nutzern einer ViFa kann diese sicherlich vergleichsweise niedriger sein. - Delicious erfährt derzeit bereits eine intensive Nutzung, so dass hier deutliche Überschneidungen mit den EconBiz Internetquellen erkennbar sind. Bei Mister Wong ist dies noch zu gering ausgeprägt. - Großes Potential ist vorhanden wenn viele Nutzerinnen und Nutzer viele Inhalte einbringen.

Abstract

This article describes two approaches for searching heterogeneous resources, which are explained as they are used in two corresponding existing systems-RIRS (Resource Integration Retrieval System) and HRUSP (Heterogeneous Resource Union Search Platform). On analyzing the existing systems, a possible framework-the MUSP (Multimetadata-Based Union Search Platform) is presented. Libraries now face a dilemma. On one hand, libraries subscribe to many types of database retrieval systems that are produced by various providers. The libraries build their data and information systems independently. This results in highly heterogeneous and distributed systems at the technical level (e.g., different operating systems and user interfaces) and at the conceptual level (e.g., the same objects are named using different terms). On the other hand, end users want to access all these heterogeneous data via a union interface, without having to know the structure of each information system or the different retrieval methods used by the systems. Libraries must achieve a harmony between information providers and users. In order to bridge the gap between the service providers and the users, it would seem that all source databases would need to be rebuilt according to a uniform data structure and query language, but this seems impossible. Fortunately, however, libraries and information and technology providers are now making an effort to find a middle course that meets the requirements of both data providers and users. They are doing this through resource integration.

Abstract

The Electronic Cultural Atlas Initiative was formed to encourage scholarly communication and the sharing of data among researchers who emphasize the relationships between place, time, and topic in the study of culture and history. In an effort to develop better tools and practices, The Electronic Cultural Atlas Initiative has sponsored the collaborative development of software for downloading and editing geo-temporal data to create dynamic maps, a clearinghouse of shared datasets accessible through a map-based interface, projects on format and content standards for gazetteers and time period directories, studies to improve geo-temporal aspects in online catalogs, good practice guidelines for preparing e-publications with dynamic geo-temporal displays, and numerous international conferences. The Electronic Cultural Atlas Initiative (ECAI) grew out of discussions among an international group of scholars interested in religious history and area studies. It was established as a unit under the Dean of International and Area Studies at the University of California, Berkeley in 1997. ECAI's mission is to promote an international collaborative effort to transform humanities scholarship through use of the digital environment to share data and by placing greater emphasis on the notions of place and time. Professor Lewis Lancaster is the Director. Professor Michael Buckland, with a library and information studies background, joined the effort as Co-Director in 2000. Assistance from the Lilly Foundation, the California Digital Library (University of California), and other sources has enabled ECAI to nurture a community; to develop a catalog ("clearinghouse") of Internet-accessible georeferenced resources; to support the development of software for obtaining, editing, manipulating, and dynamically visualizing geo-temporally encoded data; and to undertake research and development projects as needs and resources determine. Several hundred scholars worldwide, from a wide range of disciplines, are informally affiliated with ECAI, all interested in shared use of historical and cultural data. The Academia Sinica (Taiwan), The British Library, and the Arts and Humanities Data Service (UK) are among the well-known affiliates. However, ECAI mainly comprises individual scholars and small teams working on their own small projects on a very wide range of cultural, social, and historical topics. Numerous specialist committees have been fostering standardization and collaboration by area and by themes such as trade-routes, cities, religion, and sacred sites.

Abstract

For those building digital library services, the organisational barriers are sometimes far more intractable than technological issues. This was firmly flagged in one of the first workshops focusing specifically on the digital library research agenda: Digital libraries are not simply technological constructs; they exist within a rich legal, social, and economic context, and will succeed only to the extent that they meet these broader needs. The innovatory drive within the development of digital library services thrives on the tension between meeting both technical and social imperatives. The Renardus project partners have previously taken parts in projects establishing the technical basis for subject gateways (e.g., ROADS, DESIRE], EELS) and are aware that technical barriers to interoperability are outweighed by challenges relating to the organisational and business models used. Within the Renardus project there has been a determination to address these organisational and business issues from the beginning. Renardus intends initially to create a pilot service, targeting the European scholar with a single point of access to quality selected Web resources. Looking ahead beyond current project funding, it aims to create the organisational and technological infrastructure for a sustainable service. This means the project is concerned with the range of processes required to establish a viable service, and is explicitly addressing business issues as well as providing a technical infrastructure. The overall aim of Renardus is to establish a collaborative framework for European subject gateways that will benefit both users in terms of enhanced services, and the gateways themselves in terms of shared solutions. In order to achieve this aim, Renardus will provide firstly a pilot service for the European academic and research communities brokering access to those European-based information gateways that currently participate in the project; in other words, brokering to gateways that are already in existence. Secondly the project will explore ways to establish the organisational basis for co-operative efforts such as metadata sharing, joint technical solutions and agreement on standardisation. It is intended that this exploration will feed back valuable experience to the individual participating gateways to suggest ways their services can be enhanced.
Funding from the UK Electronic Libraries (eLib) programme and the European Community's Fourth Framework programme assisted the initial emergence of information gateways (e.g., SOSIG, EEVL, OMNI in the UK, and EELS in Sweden). Other gateways have been developed by initiatives co-ordinated by national libraries (such as DutchESS in the Netherlands, and AVEL and EdNA in Australia) and by universities and research funding bodies (e.g., GEM in the US, the Finnish Virtual Library, and the German SSG-FI services). An account of the emergence of subject gateways since the mid-1990s by Dempsey gives an historical perspective -- informed by UK experience in particular -- and also considers the future development of subject gateways in relation to other services. When considering the development and future of gateways, it would be helpful to have a clear definition of the service offered by a so-called 'subject gateway'. Precise definitions of 'information gateways', 'subject gateways' and 'quality controlled subject gateways' have been debated elsewhere. Koch has reviewed definitions and suggested typologies that are useful, not least in showing the differences that exist between broadly similar services. Working definitions that we will use in this article are that a subject gateway provides a search service to high quality Web resources selected from a particular subject area, whereas information gateways have a wider criteria for selection of resources, e.g., a national approach. Inevitably in a rapidly changing international environment different people perceive different emphases in attempts to label services, the significant issue is that users, developers and designers can recognise and benefit from commonalties in approach.
The Renardus project has brought together gateways that are 'large-scale national initiatives'. Within the European context this immediately introduces a diversity of organisations, as responsibility for national gateway initiatives is located differently, for example, in national libraries, national agencies with responsibility for educational technology infrastructure, and within universities or consortia of universities. Within the project, gateways are in some cases represented directly by their own personnel, in some cases by other departments or research centres, but not always by the people responsible for providing the gateway service. For example, the UK Resource Discovery Network (RDN) is represented in the project by UKOLN (formerly part of the Resource Discovery Network Centre) and the Institute of Learning and Research Technology (ILRT), University of Bristol -- an RDN 'hub' service provider -- who are primarily responsible for dissemination. Since the start of the project there have been changes within the organisational structures providing gateways and within the service ambitions of gateways themselves. Such lack of stability is inherent within the Internet service environment, and this presents challenges to Renardus activity that has to be planned for a three-year period. For example, within the gateway's funding environment there is now an exploration of 'subject portals' offering more extended services than gateways. There is also potential commercial interest for including gateways as a value-added component to existing commercial services, and new offerings from possible competitors such as Google's Web Directory and country based services. This short update on the Renardus project intends to inform the reader of progress within the project and to give some wider context to its main themes by locating the project within the broader arena of digital library activity. There are twelve partners in the project from Denmark, Finland, France, Germany, the Netherlands and Sweden, as well as the UK. In particular we will focus on the specific activity in which UKOLN is involved: the architectural design, the specification of functional requirements, reaching consensus on a collaborative business model, etc. We will also consider issues of metadata management where all partners have interests. We will highlight implementation issues that connect to areas of debate elsewhere. In particular we see connections with activity related to establishing architectural models for digital library services, connections to the services that may emerge from metadata sharing using the Open Archives Initiative metadata sharing protocol, and links with work elsewhere on navigation of digital information spaces by means of controlled vocabularies.

Abstract

The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

Abstract

The National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program comprises a set of projects engaged in a collective effort to build a national digital library of high quality science, technology, engineering, and mathematics (STEM) educational materials for students and teachers at all levels, in both formal and informal settings. By providing broad access to a rich, reliable, and authoritative collection of interactive learning and teaching resources and associated services in a digital environment, the NSDL will encourage and sustain continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning. Though the program is relatively new, its vision and operational framework have been developed over a number of years through various workshops and planning meetings. The NSDL program held its first formal funding cycle during fiscal year 2000 (FY00), accepting proposals in four tracks: Core Integration System, Collections, Services, and Targeted Research. Twenty-nine awards were made across these tracks in September 2000. Brief descriptions of each FY00 project appeared in an October 2000 D-Lib Magazine article; full abstracts are available from the Awards Section at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. In FY01 the program received one hundred-nine proposals across its four tracks with the number of proposals in the collections, services, and targeted research tracks increasing to one hundred-one from the eighty received in FY00. In September 2001 grants were awarded to support 35 new projects: 1 project in the core integration track, 18 projects in the collections track, 13 in the services track, and 3 in targeted research. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) are both providing significant co-funding on several projects, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. Thus far across both fiscal years of the program fifteen projects have enjoyed this joint support. Following is a list of the FY01 awards indicating the official NSF award number (each beginning with DUE), the project title, the grantee institution, and the name of the Principal Investigator (PI). A condensed description of the project is also included. Full abstracts are available from the Awards Section at the NSDL program site at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. (Grants with shared titles are formal collaborations and are grouped together.) The projects are displayed by track and are listed by award number. In addition, six of these projects have explicit relevance and application to K-12 education. Six others clearly have potential for application to the K-12 arena. The NSDL program will have another funding cycle in fiscal year 2002 with the next program solicitation expected to be available in January 2002, and an anticipated deadline for proposals in mid-April 2002.

Abstract

The objective of the European Library (TEL) project [TEL] was to set up a co-operative framework and specify a system for integrated access to the major collections of the European national libraries. This has been achieved by successfully applying a new approach for search and retrieval via URLs (SRU) [ZiNG] combined with a new metadata paradigm. One aim of the TEL approach is to have a low barrier of entry into TEL, and this has driven our choice for the technical solution described here. The solution comprises portal and client functionality running completely in the browser, resulting in a low implementation barrier and maximum scalability, as well as giving users control over the search interface and what collections to search. In this article we will describe, step by step, the development of both the search and retrieval architecture and the metadata infrastructure in the European Library project. We will show that SRU is a good alternative to the Z39.50 protocol and can be implemented without losing investments in current Z39.50 implementations. The metadata model being used by TEL is a Dublin Core Application Profile, and we have taken into account that functional requirements will change over time and therefore the metadata model will need to be able to evolve in a controlled way. We make this possible by means of a central metadata registry containing all characteristics of the metadata in TEL. Finally, we provide two scenarios to show how the TEL concept can be developed and extended, with applications capable of increasing their functionality by "learning" new metadata or protocol options.

Abstract

In this paper, we discuss a user study done at the formative stage of development of a Math Tools developers' community. The Math Tools digital library, which aims to collect software tools to support K-12 and university mathematics instruction, has two synergistic purposes. One is to support federated search and the other is to create a community of practice in which developers and users can work together. While much research has explored the technical problem of federated search, there has been little investigation into how to grow a creative, working community around a digital library. To this end, we surveyed and interviewed members of the Math Tools community in order to elicit concerns and priorities. These data led to rich descriptions of the teachers, developers, and researchers who comprise this community. Insights from these descriptions were then used to inform the creation of a set of metaphors and design principles that the Math Tools team could use in their continuing design work.

Abstract

The National Science Foundation's (NSF) National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL) program seeks to create, develop, and sustain a national digital library supporting science, mathematics, engineering, and technology (SMET) education at all levels -- preK-12, undergraduate, graduate, and life-long learning. The resulting virtual institution is expected to catalyze and support continual improvements in the quality of science, mathematics, engineering, and technology (SMET) education in both formal and informal settings. The vision for this program has been explored through a series of workshops over the past several years and documented in accompanying reports and monographs. (See [1-7, 10, 12, and 13].) These efforts have led to a characterization of the digital library as a learning environments and resources network for science, mathematics, engineering, and technology education, that is: * designed to meet the needs of learners, in both individual and collaborative settings; * constructed to enable dynamic use of a broad array of materials for learning primarily in digital format; and * managed actively to promote reliable anytime, anywhere access to quality collections and services, available both within and without the network. Underlying the NSDL program are several working assumptions. First, while there is currently no lack of "great piles of content" on the Web, there is an urgent need for "piles of great content". The difficulties in discovering and verifying the authority of appropriate Web-based material are certainly well known, yet there are many examples of learning resources of great promise available (particularly those exploiting the power of multiple media), with more added every day. The breadth and interconnectedness of the Web are simultaneously a great strength and shortcoming. Second, the "unit" or granularity of educational content can and will shrink, affording the opportunity for users to become creators and vice versa, as learning objects are reused, repackaged, and repurposed. To be sure, this scenario cannot take place without serious attention to intellectual property and digital rights management concerns. But new models and technologies are being explored (see a number of recent articles in the January issue of D-Lib Magazine). Third, there is a need for an "organizational infrastructure" that facilitates connections between distributed users and distributed content, as alluded to in the third bullet above. Finally, while much of the ongoing use of the library is envisioned to be "free" in the sense of the public good, there is an opportunity and a need to consider multiple alternative models of sustainability, particularly in the area of services offered by the digital library. More details about the NSDL program including information about proposal deadlines and current awards may be found at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl>.

Abstract

PhysNet offers online services that enable a physicist to keep in touch with the worldwide physics community and to receive all information he or she may need. In addition to being of great value to physicists, these services are practical examples of the use of modern methods of digital libraries, in particular the use of metadata harvesting. One service is PhysDoc. This consists of a Harvest-based online information broker- and gatherer-network, which harvests information from the local web-servers of professional physics institutions worldwide (mostly in Europe and USA so far). PhysDoc focuses on scientific information posted by the individual scientist at his local server, such as documents, publications, reports, publication lists, and lists of links to documents. All rights are reserved for the authors who are responsible for the content and quality of their documents. PhysDis is an analogous service but specifically for university theses, with their dual requirements of examination work and publication. The strategy is to select high quality sites containing metadata. We report here on the present status of PhysNet, our experience in operating it, and the development of its usage. To continuously involve authors, research groups, and national societies is considered crucial for a future stable service.

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

With the development of the World Wide Web, the "information search" has grown to be a significant business sector of a global, competitive and commercial market. Powerful players have entered this market, such as commercial internet search engines, information portals, multinational publishers and online content integrators. Will Google, Yahoo or Microsoft be the only portals to global knowledge in 2010? If libraries do not want to become marginalized in a key area of their traditional services, they need to acknowledge the challenges that come with the globalisation of scholarly information, the existence and further growth of the academic internet

Abstract

Based on a decade's experience with the Alexandria Digital Library Project, seven issues are presented that arise in creating georeferenced digital libraries, and that appear to be intrinsic to the problem of creating any library-like information system that operates on georeferenced and geospatial resources. The first and foremost issue is providing discovery of georeferenced resources. Related to discovery are the issues of gazetteer integration and specialized ranking of search results. Strong data typing and scalability are implementation issues. Providing spatial context is a critical user interface issue. Finally, sophisticated resource access mechanisms are necessary to operate on geospatial resources.
