Abstract

The aims of CATRIONA were: (1) to investigate the requirements for developing procedures and applications for cataloguing and retrieval of networked resources, and (2) to explore the feasibility of a collaborative project to develop such applications and procedures and integrate them with existing library systems. The project established that a distributed catalogue of networked resources integrated with standard Z39.50 library system OPAC interfaces with information on hard-copy resources is already a practical proposition at a basic level. At least one Z39.50 OPAC client can search remote Z39.50 OPACs, retrieve USMARC records with URLs in 856$u, load a viewer like Netscape, and use it to retrieve and display the remotely held electronic resource on the local workstation. A follow-up project on related issues is being finalised.

Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
The papers discussing the transformation of traditional tools locate the point of transformation in different places. Some, like the papers an DDC, LCC and UDC, suggest that these schemes can be imported into the networked environment and used as a basis for improving access to networked resources, just as they improve access to physical resources. While many of these papers are intriguing, I suspect that convincing those outside the profession will be difficult. In particular, Edward O'Neill and his colleagues, while offering a fascinating suggestion for preserving the Library of Congress Subject Headings and their associated infrastructure by converting them into a faceted scheme, will have an uphill battle convincing the unconverted that LCSH has a place in the online networked environment. Two papers deserve mention for taking a different approach: both Francis Devadason and Maria Ines Cordeiro suggest that we import concepts and techniques rather than realized schemes. Devadason argues for the creation of a faceted pre-coordinate indexing scheme for Internet resources based an Deep Structure indexing, which originates in Bhattacharyya's Postulate-Based Permuted Subject Indexing and in Ranganathan's chain indexing techniques. Cordeiro takes up the vitally important role of authority control in Web environments, suggesting that the techniques of authority control be expanded to enhance user flexibility. By focusing her argument an the concepts rather than an the existing tools, and by making useful and important distinctions between library and non-library uses of authority control, Cordeiro suggests that librarianship's contribution to networked access has less to do with its tools and infrastructure, and more to do with concepts that need to be boldly reinvented. The excellence of this collection derives in part from the energy, insight and diversity of the papers. Credit also goes to the planning and forethought that went into the conference itself by OCLC, the IFLA Classification and Indexing Section, the IFLA Information Technology Section, and the Program Committee, headed by editor I.C. McIlwaine. This collection avoids many of the problems of conference proceedings, and instead offers the best of such proceedings: detail, diversity, and judicious mixtures of theory and practice. Some of the disadvantages that plague conference proceedings appear here. Busy scholars sometimes interpret the concept of "camera-ready copy" creatively, offering diagrams that could have used some streamlining, and label boxes that cut off the tops or bottoms of letters. The papers are necessarily short, and many of them raise issues that deserve more extensive treatment. The issue of subject access in networked environments is crying out for further synthesis at the conceptual and theoretical level. But no synthesis can afford to ignore the kind of energetic, imaginative and important work that the papers in these proceedings represent."

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

This article describes an approach for linking geographically distributed collections of metadata so that they are searchable as a single collection. We describe the infrastructure, which uses standard Internet protocols such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP), to distribute queries, return results, and exchange index information. We discuss the advantages of using linked collections of authoritative metadata as an alternative to using a keyword indexing search-engine for resource discovery. We examine other architectures that use metadata for resource discovery, such as Dienst/NCSTRL, the AHDS HTTP/Z39.50 Gateway, and the ROADS initiative. Finally, we discuss research issues and future directions of the project. The Internet Scout Project, which is funded by the National Science Foundation and is located in the Computer Sciences Department at the University of Wisconsin-Madison, is charged with assisting the higher education community in resource discovery on the Internet. To that end, the Scout Report and subsequent subject-specific Scout Reports were developed to guide the U.S. higher education community to research-quality resources. The Scout Report Signpost utilizes the content from the Scout Reports as the basis of a metadata collection. Signpost consists of more than 2000 cataloged Internet sites using established standards such as Library of Congress subject headings and abbreviated call letters, and emerging standards such as the Dublin Core (DC). This searchable and browseable collection is free and freely accessible, as are all of the Internet Scout Project's services.
As well developed as both the Scout Reports and Signpost are, they cannot capture the wealth of high-quality content that is available on the Internet. An obvious next step toward increasing the usefulness of our own collection and its value to our customer base is to partner with other high-quality content providers who have developed similar collections and to develop a single, virtual collection. Project Isaac (working title) is the Internet Scout Project's latest resource discovery effort. Project Isaac involves the development of a research testbed that allows experimentation with protocols and algorithms for creating, maintaining, indexing and searching distributed collections of metadata. Project Isaac's infrastructure uses standard Internet protocols, such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP) to distribute queries, return results, and exchange index or centroid information. The overall goal is to support a single-search interface to geographically distributed and independently maintained metadata collections.

Abstract

These three elements reflect a refinement of NSDL's initial emphasis on collecting educational resources, materials, and other digital learning objects, towards enabling learners to "connect" or otherwise find pathways to resources appropriate to their needs. Projects are also developing both the capacities of individual users and the capacity of larger communities of learners to use and contribute to NSDL. For the FY2004 funding cycle, one hundred forty-four proposals sought approximately $126.5 million in total funding. Twenty-four new awards were made with a cumulative budget of approximately $10.2 million. These include four in the Pathways track, twelve in the Services track, and eight in the Targeted Research track. As in the earlier years of the program, sister directorates to the NSF Directorate for Education and Human Resources (EHR) are providing significant co-funding of projects. Participating directorates for FY2004 are GEO and MPS. Within EHR, the Advanced Technological Education program and the Experimental Program to Stimulate Competitive Research are also co-funding projects. Complete information on the technical and organizational progress of NSDL including links to current Standing Committees and community workspaces may be found at <http://nsdl.org/community/nsdlgroups.php>. All workspaces are open to the public, and interested organizations and individuals are encouraged to learn more about NSDL and join in its development. Following is a list of the new FY04 awards displaying the official NSF award number, 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 NSDL program site (under Related URLs see the link to NSDL program site (under Related URLs see the link to Abstracts of Recent Awards Made Through This Program.) The projects are displayed by track and are listed by award number. In addition, seven of these projects have explicit relevance to applications to pre-K to 12 education (indicated with a * below). Four others have clear potential for application to the pre-K to 12 arena (indicated with a ** below).

"... unter diesem Motto hat die Deutsche Bücherei Leipzig am 23. März 2004 auf dem Leipziger Kongress für Bibliothek und Information eine Vortragsreihe initiiert. Vorgestellt wurden Projekte, die sich im Spannungsfeld von Standardisierung und Heterogenität der Sacherschließung bewegen. Die Benutzer unserer Bibliotheken und Informationseinrichtungen stehen heute einer Fülle von Informationen gegenüber, die sie aus zahlreichen Katalogen und Fachdatenbanken abfragen können. Diese Recherche kann schnell zeitraubend werden, wenn der Benutzer mit verschiedenen Suchbegriffen und -logiken arbeiten muss, um zur gewünschten Ressource zu gelangen. Ein Schlagwort A kann in jedem der durchsuchten Systeme eine andere Bedeutung annehmen. Homogenität erreicht man klassisch zunächst durch Normierung und Standardisierung. Für die zwei traditionellen Verfahren der inhaltlichen Erschließung - der klassifikatorischen und der verbalen - haben sich in Deutschland verschiedene Standards durchgesetzt. Klassifikatorische Erschließung wird mit ganz unterschiedlichen Systemen betrieben. Verbreitet sind etwa die Regensburger Verbundklassifikation (RVK) oder die Basisklassifikation (BK). Von Spezial- und Facheinrichtungen werden entsprechende Fachklassifikationen eingesetzt. Weltweit am häufigsten angewandt ist die Dewey Decimal Classification (DDC), die seit 2003 ins Deutsche übertragen wird. Im Bereich der verbalen Sacherschließung haben sich, vor allem bei den wissenschaftlichen Universalbibliotheken, die Regeln für den Schlagwortkatalog (RSWK) durchgesetzt, durch die zugleich die Schlagwortnormdatei (SWD) kooperativ aufgebaut wurde. Daneben erschließen wiederum viele Spezial- und Facheinrichtungen mit selbst entwickelten Fachthesauri.
