What is it?
XML 1-Wire Tagging Technology lets you "tag" 1-wire devices with metadata that indicate their purposes, locations, and specific software classes to service and control them. You can locate tags within devices themselves (for those that support memory) or separately. It lets 1-wire networks be self-describing and self-configuring.

<OW:Description>Air Cond. Room 131/OW:Description>
