  • Project Users acknowledge and agree that if a catastrophic disaster occurs, resulting in complete data loss, Project Space files will not be recoverable by the Service Provider. Project Users are responsible for backing up and/or archiving their data.. Slate-Project is not backed up nor archived by the Service Provider. Information about the IU Scholarly Data Archive, which Project Users can use to archive their data, can be found here: About the Scholarly Data Archive (SDA) at Indiana University.
  • Because Slate-Project relies on group quota, Project Users agree to maintain the following permissions and group ownership:
    • Group ownership of files and directories will be the Unix Group ID (GID) associated with the Project Space.
    • All files and directories in the Project Space that do not have the correct GID will be administratively changed by the Service Provider, and notifications will be sent to the Project Member owning the data, as well as to the Project Owner.
    • All Project Users share in the responsibility to ensure that all data contained within the Project Space has the correct GID ownership.

3.2 Project Owners

  • Accept any financial responsibility for charges incurred for the Billable Allocation
  • Are considered account holders; by requesting access for additional Project Members, the Project Owner is granting permission for those Project Members to use Project Space that has been allocated to the Project Owner
  • Are responsible for the administration of data contained within the requested Project Space
  • Are responsible for authorizing and revoking Project Member access to the Project Space
  • Have the right to request that UITS-RT administratively change and/or grant permissions to allow read-write access to project data contained within the Project Space that is inaccessible to the Project Owner or that has been abandoned by former Project Users
  • If a Project Owner separates from the university and does not specify a successor, the Service Provider will discontinue access to the Project Space until such time that a Project Owner is designated according to Privacy of Electronic Information and Information Technology Resources (IT-07). A new SSA will need to be completed once a new Project Owner is designated.
  • A change in Project Owner will require a new SSA to be signed.

3.3 Project Members

  • Project Members agree to grant read-write access to the Project Owner for all data in the Project Owner's Project Space that has been assigned the Project Member's User ID (UID) throughout the lifetime of the data's existence in the Project Owner's Project Space.
  • If at any time a Project Member's data in the Project Owner's Project Space become inaccessible to the Project Owner, the Service Provider may, at the Project Owner's request, administratively grant the Project Owner read-write access to said data.
  • At the Project Owner's discretion, Project Members may be granted full access to all project data, including the ability to remove other individual's data inside the Project Space.
  • Acknowledgment of this agreement by the Project Member fulfills the "Permission granted by owner" requirement for access described in Procedure 1, section A of Privacy of Electronic Information and Information Technology Resources (IT-07).
  • Project Members can request a copy of data that has been assigned their User ID (UID) if the Project Member becomes separated from the Project Space. The Service Provider will make a best effort to fulfill the request.
