Smith,
We'll need to work out the details. The IDS Attribute is defined simply as:
“onboard” for a resident RTC or a Hostname or URI string for a network time source
However, there is no URI scheme defined for NTP/SNTP yet... Anyways, my thought was something along the lines of:
system-time-source-configured (type2 keyword | name(MAX))
This attribute identifies the source for time values on the System. Name values specify a Network Time Protocol (NTP) or Simple Network Time Protocol (SNTP) [RFC5905] server host name. The following keyword values are defined:
'dhcp': The System obtains the NTP or SNTP server address via DHCP option 42 [RFC2132].
'onboard': The System uses an internal real time clock.

Ira and I have an action item to review that specification and make recommendations about which attributes should be added, so here is my list:

Presumably the resident applications are baked into the firmware and won't show up as separate resources, while user applications are separate, "uploadable" executable-software resources?

My focus is on things an administrator might need to manage the HCD's operating configuration and maintenance.
