In this report we identify and assess different options for bringing together and mobilizing relevant stakeholders in the open access arena. This builds on previous work done in the RECODE project about the open access stakeholder ecosystem, the barriers and the enablers for open access to research data as well as on the RECODE overarching policy recommendations set out in the RECODE work package 5. We have identified a sample of existing networks and organizations to determine whether they are able to meet stakeholder needs and mobilization objectives for open access, data preservation, dissemination and use, and what these organizations can or must do in order to better mobilize stakeholders in order to meet the policy recommendations. We have identified not only examples of good practice but also the barriers not addressed by any currently available structures or organizations. While there are many forces striving to make data sharing common practice, there is still a lack of an overarching, international initiative to implement necessary requirements for making data sharing a truly international community asset. Within the European community the prerequisites and the ambitions are very different among the member states. Even amongst those countries where open access has long been on the agenda, there remain issues and barriers to be addressed. For example, training is needed in most of the stakeholder groups; investment in infrastructure building and funding is required in most institutions dealing with open access to research data; much work remains to be done to convince researchers that sharing data is a good idea. These are just a few of the obstacles that still need attention despite good, on-going efforts by individuals, organizations and states.
