Much of my personal research materials are open and available to be re-used under CC licenses. There are a few completely private spaces (where I am the only person that has access to something). There are a few restricted spaces such as individual research organization’s org archives which are only viewable to those in the organization's group. We have an RDS group, which includes the Design Group members as well as several other researchers. In all cases, users need to register and either request access or be invited to the group.
