Representing aggregate works in the digital library

This paper studies the challenge of representing aggregate works such as encyclopedias, collected poems and journals in heterogenous digital library collections. Reflecting on the materials used by humanities academics, we demonstrate the varied range of aggregate types and the problems of faithfully representing this in the DL interface. Aggregates are complex and pervasive, challenge common assumptions and confuse boundaries within organisational structures. Existing DL systems can only provide imperfect representation of aggregates, and alterations to document encoding are insufficient to create a faithful reproduction of the physical library. The challenge is amplified through concrete examples, and solutions are demonstrated in a well-known DL system and related to standard DL architecture

Goodbye to all that: Disintermediation, disruption and the diminishing library

The librarian’s role in collection development is being eroded through disintermediation. A number of factors are contributing to this: • With the Big Deals for e-journals power has shifted considerably in the publishers’ favour, and libraries’ freedom to make collection development decisions has been curtailed. If the trend towards national deals and block payments, seen for instance in the Scottish Higher Education Digital Library (SHEDL), continues, this freedom will be eroded even more; acquisitions decisions are increasingly made at the level of publisher rather than title. • A notable response to the power of the publishers’ monopoly is the open access movement, which aims to make scholarly literature freely available to all. One route is through open access publishing, where typically the author, or their institution or research funder, pays the cost of peer review and publishing. The other route is the deposit of pre- or post-prints of traditionally published materials in the author’s institutional repository or in a subject repository such as Arxiv. The librarian again is making no decisions on availability in collections. • E-book technology has enabled the introduction of so-called ‘patron selection’ or ‘patron driven acquisition’ (PDA). Suppliers of e-books are now offering libraries the opportunity to make available a fund to be spent on new e-book titles as they become popular with library users. PDA is becoming increasingly popular: a recent survey of 250 libraries in the USA showed that ‘32 have PDA programs deployed; 42 planned to have a program deployed within the next year; and an additional 90 plan to deploy a program within the next three years’ (http://www.libraries.wright.edu/noshelfrequired/?p=932). Librarians are able to impose some restrictions – for instance specifying subjects or ranges of titles; otherwise selection is taken out of the hands of librarians and entrusted to users . Initial statistics show the usage of many titles selected by users to be as high as the usage of titles selected by librarians or academics. • Google’s massive digitisation programme, although currently under legal threat, is another example. In the disintermediated world the librarian’s role is changing. It will in my view become increasingly focused not on externally produced resources, but on creating, developing and maintaining repositories of materials, whether learning objects, research data-sets or research outputs, produced in house in their own institution. Traditionally librarians have sought through the art of collection development to obtain the outputs of the world’s scholars and make them available to the scholars of their own institution – an impossible task. However our role is now being reversed: it will be to collect the outputs of our own institution’s scholars and make them freely available to the world. This task is capable of achievement and attains the aim of universal availability of scholarship to scholars. However it is not collection development as it has been practised down the years in the print world; that art, it can be argued, will no longer be needed in the era of disintermediation

Keeping Authorities "Honest or Bust" with Decentralized Witness Cosigning

The secret keys of critical network authorities - such as time, name, certificate, and software update services - represent high-value targets for hackers, criminals, and spy agencies wishing to use these keys secretly to compromise other hosts. To protect authorities and their clients proactively from undetected exploits and misuse, we introduce CoSi, a scalable witness cosigning protocol ensuring that every authoritative statement is validated and publicly logged by a diverse group of witnesses before any client will accept it. A statement S collectively signed by W witnesses assures clients that S has been seen, and not immediately found erroneous, by those W observers. Even if S is compromised in a fashion not readily detectable by the witnesses, CoSi still guarantees S's exposure to public scrutiny, forcing secrecy-minded attackers to risk that the compromise will soon be detected by one of the W witnesses. Because clients can verify collective signatures efficiently without communication, CoSi protects clients' privacy, and offers the first transparency mechanism effective against persistent man-in-the-middle attackers who control a victim's Internet access, the authority's secret key, and several witnesses' secret keys. CoSi builds on existing cryptographic multisignature methods, scaling them to support thousands of witnesses via signature aggregation over efficient communication trees. A working prototype demonstrates CoSi in the context of timestamping and logging authorities, enabling groups of over 8,000 distributed witnesses to cosign authoritative statements in under two seconds.Comment: 20 pages, 7 figure

Re-composing the digital present

This paper investigates the temporality that is produced in some recent and historical examples of media art. In exploring works by Janet Cardiff, Dennis Del Favero, and Omer Fast, I use the philosophy of Michel Serres and Gilles Deleuze to understand the convergence of temporalities that are composed in the digital present, as one moment in time overlays another moment. Developing Serres' concept of multi-temporality and Deleuze's philosophy of time and memory into a means to understand the non-linear time presented in these works, I argue that the different compositional strategies enacted by these artists provide the aesthetic grounding to experience “temporal thickness.” From here I investigate the interactive digital artworks Frames by Grahame Weinbren and Can You See Me Now? by the artist group Blast Theory. In this investigation, I understand interaction with technology, and the way that it shapes our sensory and processual experience, as a specifically temporal and temporalizing transaction, where human movements in the present are overlayed by technological processes

From manuscript catalogues to a handbook of Syriac literature: Modeling an infrastructure for Syriaca.org

Despite increasing interest in Syriac studies and growing digital availability of Syriac texts, there is currently no up-to-date infrastructure for discovering, identifying, classifying, and referencing works of Syriac literature. The standard reference work (Baumstark's Geschichte) is over ninety years old, and the perhaps 20,000 Syriac manuscripts extant worldwide can be accessed only through disparate catalogues and databases. The present article proposes a tentative data model for Syriaca.org's New Handbook of Syriac Literature, an open-access digital publication that will serve as both an authority file for Syriac works and a guide to accessing their manuscript representations, editions, and translations. The authors hope that by publishing a draft data model they can receive feedback and incorporate suggestions into the next stage of the project.Comment: Part of special issue: Computer-Aided Processing of Intertextuality in Ancient Languages. 15 pages, 4 figure

Money for Something: Music Licensing in the 21st Century

[Excerpt] The laws that determine who pays whom in the digital world were written, by and large, at a time when music was primarily performed via radio broadcasts or distributed through physical media (such as sheet music and phonograph records), and when each of these forms of music delivery represented a distinct channel with unique characteristics. With the emergence of the Internet, Congress updated some copyright laws in the 1990s. It applied one set of legal provisions to digital services it viewed as akin to radio broadcasts and another set to digital services it viewed as akin to physical media. Since that time consumers have increasingly been consuming music via digital services that incorporate attributes of both radio and physical media. However, companies that compete in enabling consumers to access music may face very different costs to license music, depending on the technology they use and the features they offer. These differences in technology and features also affect the amount of money received by songwriters, performers, music publishers, and record companies. U.S. copyright law allows performers and record labels to collectively designate an agent to receive payments and to negotiate the licensing fees that certain types of digital music services must pay to stream music to their customers. Groups representing public radio and educational stations reached voluntary agreements with the agent, SoundExchange, in 2015. Rates paid by parties that do not reach voluntary agreements with SoundExchange during a limited negotiation period are instead set by the Copyright Royalty Board (CRB), a panel of three judges appointed by the Librarian of Congress. On December 16, 2015, the CRB set rates for online music streaming services for the period 2016 through 2020. For nonsubscription services, the CRB reduced the per-stream rate it had set in the previous rate proceeding, but the costs paid by several “small” music streaming services are likely to increase. Advocates of the small streaming services have launched a petition asking Congress to either allow their previous agreements to continue indefinitely or discontinue the requirement that small streaming services pay royalties to performers and record labels. SoundExchange has objected that the rates set by the CRB do not provide adequate compensation to performers and record labels. Members have introduced several bills in the 114th Congress that would change the amounts various participants in the music industry pay or receive in royalties. These bills are controversial, as they could alter the cost structures and revenues of broadcast radio stations, songwriters, performers, and others at a time when the music industry’s overall revenues are not growing. At the same time, the U.S. Department of Justice (DOJ) is continuing a review of consent decrees it entered into with music publishers in the 1940s. The outcome could affect the extent to which songwriters can control the use of their works

Equity in the Digital Age: How Health Information Technology Can Reduce Disparities

While enormous medical and technological advancements have been made over the last century, it is only very recently that there have been similar rates of development in the field of health information technology (HIT).This report examines some of the advancements in HIT and its potential to shape the future health care experiences of consumers. Combined with better data collection, HIT offers signi?cant opportunities to improve access to care, enhance health care quality, and create targeted strategies that help promote health equity. We must also keep in mind that technology gaps exist, particularly among communities of color, immigrants, and people who do not speak English well. HIT implementation must be done in a manner that responds to the needs of all populations to make sure that it enhances access, facilitates enrollment, and improves quality in a way that does not exacerbate existing health disparities for the most marginalized and underserved

A Metadata-Enabled Scientific Discourse Platform

Scientific papers and scientific conferences are still, despite the emergence of several new dissemination technologies, the de-facto standard in which scientific knowledge is consumed and discussed. While there is no shortage of services and platforms that aid this process (e.g. scholarly search engines, websites, blogs, conference management programs), a widely accepted platform used to capture and enrich the interactions of research community has yet to appear. As such, we aim to create new ways for the members and interested people working in research communities to interact; before, during and after their conferences. Furthermore, to serve as a base to these interactions, we want not only to obtain, format and manage a body of legacy and new papers related to this community but also to aggregate several useful information and services to the environment of a discourse platform
