(Requirement) Need default authz policies that resolve problems associated with inaccessible principals
When principals die, retire, change careers, or lose interest in a research area, they may leave in the system data objects that would be otherwise useful to science but are restricted access. The authorization system should have carefully crafted default policies that encourage the public release and sharing of data, the expiration of embargo periods, and the movement of data into the public domain when it is legal and ethical to do so. Principals should be able to override these defaults to create more restrictive policies (e.g., for human subjects data) that will be respected indefinitely, but the defaults should encourage openness and sharing.
- Defaults encourage openness and sharing, without alienating principals through unexpected release of their data, etc.
