Towards open science: what we know and what we need to know

Open science presents itself as a set of policies and actions to disseminate research results in an accessible, free and reusable and reproducible way through public digital repositories. As a movement, it uses three basic elements: open access to publications; data opening (whether raw, models, specifications, or documentation); computational process opening (software and algorithms). Although it is not a new phenomenon, the term can still cause strangeness even to experienced researchers. Open access to articles, as the first element, encountered (and still finds) great resistance to becoming unanimous, although pressure from the scientific society and funding agencies has accelerated the progress of this stage. On the other hand, data opening seems to have been better received, at least in its interface related to the deposit of scientific manuscripts in the preprint format, however this is only the beginning.
