    BDNG: A dublin core-based architecture for digital libraries
    (2005-01-01) Montoya, E.; Ruiz, M.; Giraldo, J.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    Digital Libraries will be one of the main ways to access structured information through the Internet. Information related to resources or objects is known as metadata. Several metadata models have been proposed; however, the model proposed by the Dublin Core Metadata Initiative (DCMI) [1] has demonstrated great utility in digital libraries. The simplicity and generality of DCMI has facilitated the deployment of digital libraries and their interoperability. This paper proposes DCMI as metadata model in our own Digital Library Architecture (Biblioteca Digital de Nueva Generación -BDNG). We have extended DCMI and used some elements of DC-Library application profile (DC-Lib) [2] in addition to new elements not previously considered. This paper presents the metadata models for the following applications: digital library of EAFIT University (BDEeafit), integration of digital or referential libraries (BDMetaLib) and digital library for E-Learning systems (BDEI). This paper also describes the general architecture of BDNG.

    Caracterización de la ciberseguridad de activos digitales en empresas exportadoras de café en el Valle del Cauca ˗ Colombia, año 2024
    (Universidad EAFIT, 2024) Gómez Cardona, Sandra Lorena; Mayorga Sánchez, Jorge Humberto; Guerrero Latorre, Jorge Harley
    The main objective of this research is to describe the way in which the cybersecurity processes of digital assets are established in coffee exporting companies in the municipality of Cartago. The above is aimed at presenting recommendations according to the results obtained. The theoretical framework presents a wide range of approaches and postulates linked to cybersecurity issues, digital assets, and risk management. Its methodological aspect refers to a qualitative type, hand in hand with its exploratory ˗ descriptive nature, which, together with the application of a semi-structured interview, allowed the researchers to respond to the stated objectives. The results produced by the investigation process allow us to indicate that although, in the different companies investigated, incipient actions related to the cybersecurity of digital assets are carried out, it can be stated that there is no culture of cybersecurity, and that aspects such as knowledge of digital assets, risk assessment, cybersecurity policies and protocols, training and awareness, tools and technologies, and finally, regulatory compliance, are established in a very incipient way in this sector. business, highlighting that in only some companies, everything related to cybersecurity is carried out within the framework of SCS BASC, and/or the SGCS Control and Security Management System. For this reason, it is necessary to present recommendations so that these companies give the importance due to the cybersecurity of digital assets.

    Design and usability evaluation of a multi-input interface in an idTV environment
    (Springer Verlag, 2017-01-01) Téllez J.F.; Montoya J.C.; Trefftz H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    In recent years, and considering the rise of Interactive Digital Television (idTV), it has been great interest in the design of applications and services for this platform. However, the success of these applications largely depends on the ease of use and how users interact with them. For this reason, we have explored different interfaces and modes of interaction to improve the user experience with these applications in comparison with the traditional Remote-Control (RC). This article presents an interaction with idTV applications using multiple input control interfaces with different modes of interaction such as touch buttons, gesture recognition, voice recognition, and recognition of movements. These modes of interaction were validated through usability testing using a model of quasi-experimental evaluation of three dimensions, where each dimension represents respectively: users, tasks and control interfaces. As a result of the qualitative and quantitative assessments, we performed an analysis of possible improvements in the usability of a particular application of idTV. The results showed few differences between one multi-input control interface and one RC in tasks the user was familiar with, on the opposite, significant differences were found in performing tasks involving greater user interaction, such as the text input or navigation between menus. © Springer International Publishing AG 2017.
