Ownership of a BDS file

When you create a BDS (or open an existing BDS file for the first time) you will be automatically assigned ownership.

The owner of a BDS is the only user who can edit it, although other users may have simultaneous read-only access.

To disown a BDS file, select Overlays > Dataset and uncheck the Locked tickbox. Conversely checking this box allows you to become the owner (provided no-one else owns it at the time.)

   

When ownership has been relinquished, another user may become the owner by checking the Locked tickbox on their own system.

The new owner then gets editable access to the BDS.

Other users of the BDS

Other users can also call up the BDS into their Overlays dialog but with a maximum status of Hittable. This means they can view it but not edit it.

The version of the BDS viewed by non-owners is always the most recent version saved to disk. Therefore ensure you save the file first before relinquishing ownership (or before a non-owner can receive updates made in the current session).

To view the most recent changes on a BDS file, either:

• Use Regenerate (Home > Map). This gets the latest saved version of all referenced datasets, including BDS files which have been updated by other users,
  
  or

• Select the Automatically refresh BDS datasets option on the Miscellaneous page of the Options dialog. SIS Desktop looks across the network every few seconds to check whether the BDS file has been updated since it last looked.
