The Model repository does not lock the asset when you open it. The Model repository locks the asset only after you begin to edit it. For example, the Model repository locks a mapping specification when you insert a cursor in an editable field or rename the asset.

You can use more than one client tool to develop an asset. For example, you can edit an asset on one machine and then open the asset on another machine and continue to edit it. When you return to the first machine, you must close the asset and reopen it to regain the lock. The same principle applies when a user with administrative privileges unlocks an asset that you had open.
