    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.

    CME – A web application framework learning technique based on concerns, micro-learning and examples
    (SPRINGER, 2018-01-01) Correa, D.; Isaza, F.A.; Mazo, R.; Giraldo, G.L.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    Nowadays the use of Web Application Frameworks has been the default choice to develop software applications inside the web domain. These frameworks provide many benefits such as: faster development, enhanced security, and clearer structure of code. However, web application frameworks have a high learning curve and each time someone wants to learn a framework, a recurrent question arises: How to reduce that learning curve and be able to use a new web application framework in a short time? Several learning techniques have been used in the context of frameworks; for instance, example-based learning, tutorials, cookbooks, and tools. Nevertheless, those approaches have their own limitations and the question about what is the best way to learn soon those frameworks remains open. In this paper, we introduce a new web application framework learning technique called CME (Concerns, Micro-learning and Examples). This technique defines a customized learning path that a novice developer should follow to learn to use a web application framework. The learning path was built as a mix of concerns, micro-learning and example-based learning concepts. To validate this technique, we carry out a quasi-experiment about a web application framework learning and the development of small web applications with: (i) the use of CME and (ii) the use of a cookbook. The quasi-experiment results showed preliminary evidence that when using CME, novice developers become more operational to develop small web applications in a reduced period of time compared with the use of a cookbook. © Springer International Publishing AG, part of Springer Nature 2018.

    ReWeb3D - Enabling desktop 3D applications to run in the web
    (2013-01-01) Glander, T.; Moreno, A.; Aristizabal, M.; Congote, J.; Posada, J.; Garcia-Alonso, A.; Ruiz, O.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Laboratorio CAD/CAM/CAE
    Currently, 3D rendering is accessible within Web browsers through open standards such as WebGL, X3D, and X3DOM. At the same time, there is wealth of mature desktop software which comprises algorithms, data structures, user interfaces, databases, etc. It is a challenge to reuse such desktop software using the Web visualization resources. In response to this challenge, this article presents a novel framework, called ReWeb3D, which minimizes the redevelopment for migration of existing 3D applications to the Web. The redeployed application runs on a Web server. ReWeb3D captures low-level graphic calls including geometry, texture, and shader programs. The captured content is then served as a WebGL-enabled web page that conveys full interactivity to the client. By splitting the graphics pipeline between client and server, the workload can be balanced, and high-level implementation details and 3D content are hidden. The feasibility of ReWeb3D has been tested with applications which use OpenSceneGraph as rendering platform. The approach shows good results for applications with large data sets (e.g. geodata), but is less suited for applications intensive in animations (e.g. games).
