The study should investigate the necessary conditions for the publication of such software. Is all software suitable for publication or not; are there any legal barriers in the Member States for the adoption of such a policy and under what licence(s) should the software be published? With a view to maximizing the potential benefit of publishing the software, should new public software developments take particular requirements into account (such as more emphasis on interoperability, standards, design allowing adaptation to multilingualism, improved documentation etc.)? Would such a policy contribute to standardization processes (de facto or de jure)? Would the opportunity for re-use lead to cost-savings, better systems and accelerate uptake? The study should include case studies. Are there any negative side-effects (such as unintended interference with the market), and how should such side-effects be handled?
