Information technology — UPnP Device Architecture — Part 27-1: Friendly device control protocol — Friendly information update service (ISO/IEC 29341-27-1:2017)
This service definition is compliant with the UPnP Device Architecture version 1.0. It defines aservice type referred to herein as FriendlyInfoUpdate service . It is scoped to the DeviceDescription Document (DDD) and is a service allowing control points to create orderlyupdates to the <friendlyName> and <iconList> elements. Once a change has takenplace the status of the DDD might not reflect that of the advertised description because thedevice can not leave the network during ongoing activities. Therefore a state variable isprovided to indicate if the DDD contains non-advertised (pending) values. If for any reasonthe device goes off line, power cycles, or reboots it will most likely advertise its new DDD. IfDeviceProtection UPnP DP is implemented on the device then it will support restrictingcontrol point actions to control points with specific Roles.
