I agree with what Harry is saying. I want to see us working on a
replacement for SNMP and the MIB which I definitely see as being inside the
scope of the charter. Doing this will give us a solution that works inside
the firewall as well as outside the firewall.

Nothing in the charter leads me to believe my perspective on remote
management to the same granularity as currently available via SNMP is
excluded or out of scope. I suggest we continue to strive for consensus and
make appropriate modifications or clarifications to the charter before
sending out for approval.
I'd like to hear from some others.

Harry,
Your comments reflect a different perspective on the activity, or at least
on the priorities. It seems that you see the effort as a general
replacement for SNMP, perhaps defining some replacement to the MIBs. What
I see as the most pressing need is to provide for remote access to existing
data bases, be they MIBs or the data current accessed by web pages, or some
internal parameters.
I also do not see this in terms of a management station canvassing to see
what device supports what. In general, I do not think that that sort of
fishing would be allowed in many enterprises. Rather, I see the device
being registered with the remote server to provide reposts according to
some pre-arraigned agreement on what parameters would be monitored. Indeed,
the idea was to define the transport and a general formal by which elements
could be queried or specified. Although items such as you mention (size of
media in trays) would not be excluded, it does not seem the sort of thing
that would be of interest to a remote server. I will post the list of
things brainstormed at the BOF.
I intended the proposed Charter to be clear that this activity was to use
the path intended for web browsing to allow authorized but non-enterprise
agencies to monitor (for usage information, for example) and perhaps do
specific maintenance (for updates or upgrades, for example) to
on-enterprise site equipment. it was not the intent that this be a general
SNMP replacement. Perhaps you may want to look at the charter again before
we send it out for final approval. ( I have attached the draft as modified
at Maui). By the way, the title is Charter Proposal for PWG WEB-Based
Monitoring and Management, hence WBMM.

SNMP has GET, SET, GETBULK etc. What types of commands would we like to see
in WBMM (what does WBMM stand for, anyway!?... perhaps separate
discussion... aren't we forgetting the U word... "Universal Deice and
Services Management")
Back to the topic...
I'm thinking we will want to improve on the interfaces and commands based
on what we have learned over the years implementing the Printer MIB. Please
share your thoughts. Here are some of mine. We need...
1. A way to query what attributes are settable and which are not (we
learned, with SNMP, that "MaxAccess" isn't always that helpful).
2. A way to query attribute (elements?) either singularly (tell me size of
media in "main" tray), in bulk (give me the "input group"), or filtered
(tell me the name of each tray; tell me all trays which are loaded with
transparency).
3. If we end up with mandatory and optional commands or interfaces, a way
to query which are supported in a particular implementation (describe via
WSIL/WSDL?).
