A review of software applications for managing digital repositories is presented. Information managers have at their disposal several alternatives beyond those that have achieved greater popularity in the area of academic repositories: DSpace and EPrints. Existing alternatives have evolved and implemented mayor improvements in their more recent versions, with the aim of adopting the latest standards for the semantic web and linked data. This paper provides a description of the new features incorporated into the latest versions of the most popular open-source products. The selection has been made using as a reference the information offered by the Digital Preservation Coalition (DPC), Digital Curation Center (DCC), National Digital Stewardship Alliance (NDSA), and Open Preservation Foundation. The conclusions of the study indicate that the combined use of different tools is needed to support a complete archive and digital preservation program, as no single application seems to be able to provide the features required for an effective strategy. Resumen Se presenta una revisión del estado de las aplicaciones informáticas para la gestión de repositorios digitales. Los gestores de repositorios disponen de distintas alternativas, al margen de las que han alcanzado una mayor popularidad en el área de los repositorios académicos, en particular DSpace o EPrints, que han evolucionado sustancialmente en sus últimas versiones. Esta evolución responde principalmente a la adopción de nuevos estándares diseñados en el contexto de la web semántica y los datos abiertos enlazados, y a la necesidad de incorporar a los productos funciones para la preservación digital. Se describe la evolución y las novedades incorporadas en las últimas versiones de los principales programas de código abierto u open source de gestión de repositorios atendiendo a los puntos anteriores. La selección se ha completado a partir de los datos disponibles en sitios de referencia como la Digital Preservation Coalition (DPC), Digital Curation Center (DCC), National Digital Stewardship Alliance (NDSA) y la Open Preservation Foundation. Las conclusiones señalan que una estrategia de archivo y preservación digital exige la utilización conjunta de distintos softwares, pues ninguno integra todos los componentes necesarios para implementar una estrategia de archivo digital y preservación efectiva.

DCC DIFFUSE Standards Frameworks aims to offer domain specific advice on standards relevant to digital preservation and curation, to help curators identify which standards they should be using and where they can be appropriately implemented, to ensure authoritative digital material. The Project uses the DCC Curation Lifecycle Model and Web 2.0 technology, to visually present standards frameworks for a number of disciplines. The Digital Curation Centre (DCC) is actively working with a different relevant organisations to present searchable frameworks of standards, for a number of domains. These include digital repositories, records management, the geo-information sector, archives and the museum sector. Other domains, such as e-science, will shortly be investigated.

This article introduces the National Library of Australia’s Digital Preservation Knowledge Base which helps the Library to manage digital objects from its collections over the long term. The Knowledge Base includes information on file formats, rendering software, operating systems, hardware and, most importantly, the relationships between them. Most of the work on the Knowledge Base over the last few years has been focused on the mapping of functional relationships between file formats, their versions and software applications. The information is gathered through unique empirical research and is initially being recorded in a multiple-worksheet Excel file in a semi-structured format, though development of a prototype graph database is underway.

Combined Use

This document addresses the development of a novel methodology to identify the actual maintenance factor of the luminaires of an outdoor lighting installation in order to assess their lighting performance. The method is based on the combined use of Radiance, a free and open-source tool, for the modeling and simulation of lighting scenes, and GenOpt, a generic optimization program, for the calibration of the model. The application of this methodology allows the quantification of the deterioration of the road lighting system and the identification of luminaires that show irregularities in their operation. Values lower than 9% for the error confirm that this research can contribute to the management of street lighting by assessing real road conditions.

This study examines the development of open source software supporting e-commerce (EC) or e-business (EB) capabilities. This entails a case study within a virtual organization engaged in an organizational initiative to develop, deploy, and support free/open source software systems for EC or EB services, like those supporting enterprise resource planning. The objective of this study is to identify and characterize the resource-based software product development capabilities that lie at the center of the initiative, rather than the software itself, or the effectiveness of its operation in a business enterprise. By learning what these resources are, and how they are arrayed into product development capabilities, we can provide the knowledge needed to understand what resources are required to realize the potential of free EC and EB software applications. In addition, the resource-based view draws attention to those resources and capabilities that provide potential competitive advantages and disadvantages to the organization in focus.

Psychophysical Tests

Abstract Psychophysical tests are commonly carried out using software applications running on desktop or laptop computers, but running the software on mobile handheld devices such as smartphones or tablets could have advantages in some situations. Here, we present StimuliApp, an open-source application in which the user can create psychophysical tests on the iPad and the iPhone by means of a system of menus. A wide number of templates for creating stimuli are available including patches, gradients, gratings, checkerboards, random-dots, texts, tones or auditory noise. Images, videos and audios stored in files could also be presented. The application was developed natively for iPadOS and iOS using the low-level interface Metal for accessing the graphics processing unit, which results in high timing performance.

West African manuscripts are numerous and varied in forms and contents. There are thousands of them across West Africa. A significant portion of them are documents written in Arabic and Ajami (African languages written in Arabic script). They deal with both religious and nonreligious subjects. The development of these manuscript traditions dates back to the early days of Islam in West Africa, in the 11th century. In addition to these Arabic and Ajami manuscripts, there have been others written in indigenous scripts. These include those in the Vai script invented in Liberia; Tifinagh, the traditional writing system of the Amazigh (Berber) people; and the N’KO script invented in Guinea for Mande languages. While the writings in indigenous scripts are rare less numerous and widespread, they nonetheless constitute an important component of West Africa’s written heritage. Though the efforts devoted to the preservation of West African manuscripts are limited compared to other world regions, interest in preserving them has increased. Some of the initial preservation efforts of West African manuscripts are the collections of colonial officers. Academics later supplemented these collections. These efforts resulted in important print and digital repositories of West African manuscripts in Africa, Europe, and America. Until recently, most of the cataloguing and digital preservation efforts of West African manuscripts have focused on those written in Arabic. However, there has been an increasing interest in West African manuscripts written in Ajami and indigenous scripts. Important West African manuscripts in Arabic, Ajami, and indigenous scripts have now been digitized and preserved, though the bulk remain uncatalogued and unknown beyond the communities of their owners.
