D-Lib Magazine Pioneered Web-Based Scholarly Communication

The web began with a vision of, as stated by Tim Berners-Lee in 1991, “that much academic information should be freely available to anyone”. For many years, the development of the web and the development of digital libraries and other scholarly communications infrastructure proceeded in tandem. A milestone occurred in July, 1995, when the first issue of D-Lib Magazine was published as an online, HTML-only, open access magazine, serving as the focal point for the then emerging digital library research community. In 2017 it ceased publication, in part due to the maturity of the community it served as well as the increasing availability of and competition from eprints, institutional repositories, conferences, social media, and online journals – the very ecosystem that D-Lib Magazine nurtured and enabled. As long-time members of the digital library community and frequent contributors to D-Lib Magazine, we reflect on the many innovations that D-Lib Magazine pioneered and were made possible by the web, including: open access, HTML-only publication and embracing the hypermedia opportunities afforded by HTML, persistent identifiers and stable URLs, rapid publication, and community engagement. Although it ceased publication after 22 years and 265 issues, it remains unchanged on the live web and still provides a benchmark for academic serials and web-based publishing

Building and Using Digital Libraries for ETDs

Despite the high value of electronic theses and dissertations (ETDs), the global collection has seen limited use. To extend such use, a new approach to building digital libraries (DLs) is needed. Fortunately, recent decades have seen that a vast amount of “gray literature” has become available through a diverse set of institutional repositories as well as regional and national libraries and archives. Most of the works in those collections include ETDs and are often freely available in keeping with the open-access movement, but such access is limited by the services of supporting information systems. As explained through a set of scenarios, ETDs can better meet the needs of diverse stakeholders if customer discovery methods are used to identify personas and user roles as well as their goals and tasks. Hence, DLs, with a rich collection of services, as well as newer, more advanced ones, can be organized so that those services, and expanded workflows building on them, can be adapted to meet personalized goals as well as traditional ones, such as discovery and exploration

Integração e interoperabilidade no acesso a recursos informacionais eletrônicos em C&T: a proposta da Biblioteca Digital Brasileira

Descreve as opções tecnológicas e metodológicas para atingir a interoperabilidade no acesso a recursos informacionais eletrônicos, disponíveis na Internet, no âmbito do projeto da Biblioteca Digital Brasileira em Ciência e Tecnologia, desenvolvido pelo Instituto Brasileiro de Informação em Ciência e Tecnologia (IBICT). Destaca o impacto da Internet sobre as formas de publicação e comunicação em C&T e sobre os sistemas de informação e bibliotecas. São explicitados os objetivos do projeto da BDB de fomentar mecanismos de publicação pela comunidade brasileira de C&T, de textos completos diretamente na Internet, sob a forma teses, artigos de periódicos, trabalhos em congressos, literatura “cinzenta”, ampliando sua visibilidade e acessibilidade nacional e internacional, e também de possibilitar a interoperabilidade entre estes recursos informacionais brasileiros em C&T, heterogêneos e distribuídos, através de acesso unificado via um portal, sem a necessidade de o usuário navegar e consultar cada recurso individualmente

Developing an Institutionally-Funded Publishing Channel: Context and Considerations for Key Issues

A Report prepared for the Creating an Open Access Paradigm for Scholarly Publishing ProjectCornell's Internet First University Press (IFUP) seeks to explore the practical viability of direct institutional funding for serial and monographic publication of an institution?s faculty research. To effect fundamental change, such an institutional funding model must not simply shift the costs from the library to other budgets within the institution. It must disaggregate and restructure the academic publishing value chain to separate the services that facilitate publication from monopolistic control of the material published. To attain this goal in practical terms, the IFUP must demonstrate a sustainable economic model and guarantee author autonomy in the choice of publishing venue. This report reviews past and current academic publishing initiatives that provide context and practical insight into how an institutionally sponsored publishing model might be designed and implemented to satisfy these essential requirements

Metadata harvesting for content-based distributed information retrieval

We propose an approach to content-based Distributed Information Retrieval based on the periodic and incremental centralisation of full content indices of widely dispersed and autonomously managed document sources. Inspired by the success of the Open Archive Initiative’s protocol for metadata harvesting, the approach occupies middle ground between content crawling and distributed retrieval. As in crawling, some data moves towards the retrieval process, but it is statistics about the content rather than content itself; this grants more efficient use of network resources and wider scope of application. As in distributed retrieval, some processing is distributed along with the data, but it is indexing rather than retrieval; this reduces the costs of content provision whilst promoting the simplicity, effectiveness, and responsiveness of retrieval. Overall, we argue that the approach retains the good properties of centralised retrieval without renouncing to cost-effective, large-scale resource pooling. We discuss the requirements associated with the approach and identify two strategies to deploy it on top of the OAI infrastructure. In particular, we define a minimal extension of the OAI protocol which supports the coordinated harvesting of full-content indices and descriptive metadata for content resources. Finally, we report on the implementation of a proof-of-concept prototype service for multi-model content-based retrieval of distributed file collections

Contexts and Contributions: Building the Distributed Library

This report updates and expands on A Survey of Digital Library Aggregation Services, originally commissioned by the DLF as an internal report in summer 2003, and released to the public later that year. It highlights major developments affecting the ecosystem of scholarly communications and digital libraries since the last survey and provides an analysis of OAI implementation demographics, based on a comparative review of repository registries and cross-archive search services. Secondly, it reviews the state-of-practice for a cohort of digital library aggregation services, grouping them in the context of the problem space to which they most closely adhere. Based in part on responses collected in fall 2005 from an online survey distributed to the original core services, the report investigates the purpose, function and challenges of next-generation aggregation services. On a case-by-case basis, the advances in each service are of interest in isolation from each other, but the report also attempts to situate these services in a larger context and to understand how they fit into a multi-dimensional and interdependent ecosystem supporting the worldwide community of scholars. Finally, the report summarizes the contributions of these services thus far and identifies obstacles requiring further attention to realize the goal of an open, distributed digital library system

Concepts for handling heterogeneous data transformation logic and their integration with TraDE middleware

The concept of programming-in-the-Large became a substantial part of modern computerbased scientific research with an advent of web services and the concept of orchestration languages. While the notions of workflows and service choreographies help to reduce the complexity by providing means to support the communication between involved participants, the process still remains generally complex. The TraDE Middleware and underlying concepts were introduced in order to provide means for performing the modeled data exchange across choreography participants in a transparent and automated fashion. However, in order to achieve both transparency and automation, the TraDE Middleware must be capable of transforming the data along its path. The data transformation’s transparency can be difficult to achieve due to various factors including the diversity of required execution environments and complicated configuration processes as well as the heterogeneity of data transformation software which results in tedious integration processes often involving the manual wrapping of software. Having a method of handling data transformation applications in a standardized manner can help to simplify the process of modeling and executing scientific service choreographies with the TraDE concepts applied. In this master thesis we analyze various aspects of this problem and conceptualize an extensible framework for handling the data transformation applications. The resulting prototypical implementation of the presented framework provides means to address data transformation applications in a standardized manner
