Kindly note that the documents presented here have not been formally confirmed by representatives of the Sites yet, those are just drafts discussed extensively within the community expected to form the infrastructure. The infrastructure is in pilot operation, neverheless formally it has not been established yet.
In addition, you may note that the establishing documents work with the idea that membership will be available completely free of charge. As approach to financing for infrastructures like the Science Mesh in EOSC is under discussions and developments, it must be stated that it may not be the case and it may be necessary to form a consortium as a legal entity and also requiring a membership fee. Central part of the infrastructure is nevertheless intentionally designed to be minimal, so that costs of its operations are kept as low as possible. And of course, if another financing source is found, membership fees could go even lower.
The infrastructure is about to be formally established in the middle of 2022.
Governance structure of the Science Mesh is based on following bodies:
Sites apply for membership by signing a Site Declaration. The Declaration is purposefully kept as brief as possible and limited just to basic principles of the infrastructure. It refers to the Science Mesh Policy Framework Constitution, where governance structure is defined as well as general outlines of standard operational procedures and requirements for the sites.
While those documents will surely be examined by law departments of joining sites, we should point out that section 3.1 of the Science Mesh Policy Constitution summarises requirements for membership, among others listing several Terms and Conditions and policies the sites are required to have in place.
