The aim of the Working Group (WG) is to collect, prepare, edit and make available through open source code repository of HOSI (GitHub) all kinds of open software that can be used by organisations and scientists to support Open Science (e.g. publications repository, data catalogs). The members of WG are encouraged to emphasise the availability of software that is as easy to use as possible in an immediate way (e.g. maturity, packaging, documentation).
