<p>presented at the FOSDEM 2013 "FOSS for Scientists" devroom, 2013-02-02, Bruxelles, BE</p> <p> </p> <p> </p> <p>Software is science, in the sense that when developed in the course of computational science research, it can't be classified as "infrastructure" or "support". If a telescope is infrastructure for astronomy, then its equivalent or computational mathematics is a supercomputer. On the other hand, code produced to prove a theorem, simulate an explosion or study an image denoising algorithm is the subject-matter of the science being investigated.</p> <p>We need this work to be recognized and time and effort invested in it must be rewarded by scholarship standards. On the other hand, when science is based on software foundations, the computational part of the research should be subject to validation by the scientific method. This implies that every program used in the elaboration of a research paper should, at least, be usable by referees, and if possible be publicly available is source form. Open Source software is part of the equation, but it is not sufficient to answer the questions raised here.</p> <p>During this talk, we will present the rationale for the "Software as Science" approach, in relation with other ideas, chiefly Reproducible Research and Open Science, and we will mention recent workshops and conferences, as well as groups, projects and institutions involved in these dynamics. We will list and detail numerous obstacles to the recognition of software in the scientific method and open questions on that matter: identification and citation, standard APIs and languages, verification and validation, copyright and patents, limits to reproducibility, etc.</p> <p>Finally, we will present our own project, IPOL, a research journal on image processing, in which every algorithm is published (Open Access license) and reviewed with the source code of its implementation (Open Source license) and a web interface to test it and browse archived experiments.</p>
