When an administrator changes any facet of this information,
the change is simultaneous on all internal networks and the
Internet. A DOI is a permanent identifier, analogous to a
telephone number for life, so tomorrow and years from now a
user can locate the product and related resources wherever
they may have been moved or archived to."
The IDF provides a limited, text-only, online demonstration.
When sweeping with the cursor over a linked item, a pop-down
menu of options is presented. These options are pre-defined
and customized by the content creators and owners. In the
first example above (book purchase options) the DOI resolves
to retail outlets (categorized by book formats), information
about the title and the author, digital rights management
information (permissions), and more. The DOI server generates
this information in "real time", "on the fly". But it is the
author, or (more often) the publisher that choose the
information, its modes of presentation, selections, and
marketing and sales data. The ingenuity is in the fact that
the DOI server's files and records can be updated, replaced,
or deleted.
