What is the SSH Open Marketplace? The SSH Open Marketplace, built under the SSHOC project, is a discovery portal which pools and harmonises all the SSH tools (services and software), datasets, training materials and activities (workflows and scenarios) useful for SSH research communities, offering a high quality and contextualised answer at every step of the SSH research data life cycles. As the Social Sciences and Humanities branch of the EOSC, the SSHOC project is developing the Marketplace for and with SSH research communities. We collaborate closely with these communities, the future users of the Marketplace, researchers, librarians, research infrastructure members, or service providers, policy-makers and citizen scientists, to develop a Marketplace that will serve their needs. We collaborate closely with different stakeholders working in the EOSC environment; it is only natural that the creation of the SSH Open Marketplace takes into consideration its future embedding in the larger science landscape. We are working towards establishing the SSH Marketplace among the other EOSC catalogues and marketplaces such as the EOSC-Hub, eInfraCentral or OpenAire catalogues.
