When first saving an item to the empower library further information is automatically added to it that enables its identification. This item receives an individual ID number and a time stamp.
If for example this item is now reused and duplicated within a different context, a link between the original object and its copy will be created ‑ they now constitute an update union. Should you now save a single slide to the company library and also save it someplace else in empower both the original slide and its copy become linked. Both items – original slide and copy – now display a link symbol in their preview, which denotes their connection.
If changes to the original slide are made at a later date and these are updated in the library empower will be able to recognize this via the time stamp and the copy of the slide will receive an update notification. The orange symbol shows that this element has one or more updates available. With a right-click, you have the ability to administer the updates directly in the library. More information can be found in chapter “Administering updates in library”.
If you insert the copy of a slide into a presentation, the update wizard will open which will present you with different options in dealing with the updates. For further information, please refer to chapter Update Wizard.
Update distribution is not only initiated for elements placed in the empower library, but also if a copy of the original element is saved locally. If a copy of an element from the library is saved locally, its ID and time stamp are also saved. If this element is opened at a later date, empower will use this information to establish a connection to the original element and will send an update notification if an update is available for this element.
Update distribution can also consist of multiple elements. If a slide is used in multiple presentations (saved locally and/or in the empower library), the original element and its copies will be joined in an update union. Changes to the original element will send update notifications to all its copies.
