What are the supported Permissions in an OMERO Group?

Permissions in OMERO were all made private in version leading up to 4.1 because of various difficulties with the security system.

In order to allow group-sharing, a revamp of the permissions took place for 4.2. The intention is that all object graphs (e.g. Project/Dataset/Image) will belong to a single group, and all objects will have the same read permissions.

Mixing objects with different group-ownerships or different read-permissions will not be allowed. Further, a query will only ever return objects belonging to the currently selected group.

The various permissions levels are as follows:

• Private: All data in this group is only visible to the user who owns it and the group owners. The group owner can view the data for other group members but not make any edits (same as read-only behaviour).

• Collaborative - Read-only: Users in groups with this permission setting can view each others' data, but cannot edit or annotate another user's data. You can view another users' images but not comment, rate or tag their images.

• Collaborative: Users in a collaborative group can view and annotate the data belonging to other users. You can tag another user's images or use their tags to annotate your own images. You can add comments to their images and save your own rendering settings for each image. However, you cannot edit the names of their images, projects, datasets, tags etc.
