OSIRIX: open source multimodality image navigation software Findings: Open source software and open access to research findings are of great use to scholars in developing… Design/methodology/approach: A review of key developments in the open access and open source movement is provided. Purpose: The purpose of this paper is to describe the open access and open source movement in the digital library world. Open Access, Open Source and Digital Libraries: A Current Trend in University Libraries around the World First, it presents a brief review of the literature, emphasizing the need to evaluate open source solutions carefully in order to minimize Total Cost of Ownership. This article discusses best practices for evaluating open source software for use in library projects, based on the authors' experience evaluating electronic publishing solutions. In this presentation we discuss the usage of free and open source software for weather forecasting in the context of research flight planning, and highlight how the field campaign work benefits from using open source tools and open standards.Įvaluating Open Source Software for Use in Library Initiatives: A Case Study Involving Electronic Publishing The tool has been implemented in Python and has also been released as open source (Rautenhaus et al., Geosci. These open source libraries and open standards helped to implement the "Mission Support System", a Web Map Service based tool to support weather forecasting and flight planning during field campaigns. Of particular value are the Python programming language with its extension libraries NumPy, SciPy, PyQt4, Matplotlib and the basemap toolkit, the NetCDF standard with the Climate and Forecast (CF) Metadata conventions, and the Open Geospatial Consortium Web Map Service standard. To forecast the weather situation during aircraft-based atmospheric field campaigns, we employ a tool chain of existing and self-developed open source software tools and open standards. Weather forecasting with open source software We also briefly comment on the impact on academic careers of engaging in software projects. In particular, we discuss the roles of code, documentation, communities, project management and licenses. In this paper, we consider what we have found to be the necessary ingredients for successful scientific software projects and, in particular, for software libraries upon which the vast majority of scientific codes are built today. This is particularly apparent in the commonly held view that writing successful software packages is largely the result of simply ‘being a good programmer’ when in fact there are many other factors involved, for example the social skill of community building. ![]() Yet, while we regularly publish detailed accounts about the results of scientific software, and while there is a general sense of which numerical methods work well, our community is largely unaware of best practices in writing the large-scale, open source scientific software upon which our discipline rests. Software is the backbone of scientific computing. What makes computational open source software libraries successful? While it is accepted that print media can survive for centuries with… To organize, store, and retrieve digital content, many libraries as well as archiving centers are using either proprietary or open-source software. Barve, Sunita Amin, Saifulĭigital archives and digital library projects are being initiated all over the world for materials of different formats and domains. ![]() JHelioviewer is part of the ESA/NASA Helioviewer Project.Digital Preservation in Open-Source Digital Library SoftwareĮRIC Educational Resources Information Center For further information about the project, contact Daniel Müller (Daniel.Mueller esa.int). JHelioviewer is being developed as open-source software by the ESA JHelioviewer Team.

These features minimize the data volume transmitted while maximizing its usability. The JPEG 2000 Interactive Protocol (JPIP) enables serving data in a highly compressed, quality-progressive, region-of-interest-based stream. JPEG 2000 offers many useful new features and has the potential to revolutionize the way high-resolution image data are disseminated and analyzed. ![]() JHelioviewer is visualization software for solar image data based on the JPEG 2000 compression standard. However, work on JHV version 2 continues. The project is in maintenance mode and issues are fixed on a best-effort basis. Downloads are still available from and functional. ![]() This repository contains the no longer actively developed version 3 of JHelioviewer.
