Distributed collaboration capabilities are offered as part of an early adopter program available to interested ArcGIS Online organizations. You must have an ArcGIS Enterprise 10.5.1 base deployment to participate in the early adopter program. For more information and to apply for the program, visit the Enterprise to Online Collaboration early adopter website.
When organization administrators have created a collaboration between two or more portals, collaboration members can share content with participants using groups that are associated with a collaboration workspace.
In a collaboration, content is shared according to the sharing settings of the organization where the data originated. For example, if an ArcGIS Server service item is shared to the organization where it originated, as well as to a group associated with a collaboration workspace, members of other participating portals are still prompted for credentials when adding the service to a map.
You can send content from your organization to a participant if the collaboration host (that is, your organization) defined the access mode for the collaboration workspace as either Send or Send and Receive. To send content, share the items with the group that is associated with the collaboration workspace. The content will be sent to the host based on the sync settings determined by the guest administrator.
Once content has been shared to the collaboration, participants can share the content again inside or outside their organization, including in any other collaborations in which they participate. Participants can also build on the shared items to create their own information products. However, once content has been shared, it cannot be reshared back to its source.
If you remove items from a group associated with a collaboration workspace, the items are removed from the recipient's groups at the next sync.
You can receive content from a participating portal if the collaboration host (that is, your organization) defined the access mode for the collaboration workspace as either Receive or Send and Receive. When another portal participating in the collaboration shares content, your portal will receive a copy of the content in the group associated with the collaboration workspace. Content will refresh and appear in the group according to the schedule set by the collaboration's host.
Items received from other organizations will display the Collaborated Content badge. This badge will not be visible on items in the portal from which they originate.
If you share content to a group in your portal and your access mode in the collaboration is Receive, the content will remain in the group but will not be shared to collaboration participants in other portals.
