Just as for the Media, it is possible to manage lock and unlock also for the Documents. The feature identified by an open or closed lock highlights to the system which documents you wish to keep private and which you wish to keep more easily sharable.
It is possible to manage the default status of the padlock in the Settings Panel (gear symbol at the bottom left), by choosing the Documents & Media item and enabling the Default Status.
Artshell allows in fact, during export and sharing phases, to decide which elements to share per single artwork. To simplify and quicken the process of selection, the system pre-selects the documents of every category with open lock, leaving the user the chance to select the documents with closed lock.
We suggest you to manage the state of the lock on the artworks documents, by choosing which one you wish to keep private in your archive (and thus you wish to seldom share) and which others you wish to show every time you will export or share the record of an artwork.
