PRESS RELEASE
Goals are
awareness of IPP
promote the Printer Working Group
Requests on the e-mail list were
1. Remove most of the history to avoid a conflict with a prior Novell
press release.
E.g., It was formed by the Printer Working Group in November and
chartered by the IETF in March.
2. Tone down the discussion of Fax
Could perhaps have a scenario that shows how remote print delivery would
provide an alternative to making a phone call to transmit documents.
3. Give more credit to DPA
Discussion concensus was that we should not mention DPA, but should
only refer to prior (DPA, LPR, ...) standards efforts.
"Builds on the broad experience with working with prior printing job
submission standardization efforts."
Action Items, due end of day Monday, April 21
Roger will draft how world will change based on the
Scenario/Requirements document
Don will get a quote from an analyst and will assemble the contributions
Carl-Uno will rewrite history
LAST WEEKS MEETING
Directory Schemas
There is an ad hoc group that is designing a registry for directory
schemas; they are not proposing a syntax for the schema, however.
In the directory document we need to discuss how (cached) directory
entries will be kept up with the actual properties of the printers
on-line when printers can be "hot switched"
Protocol
The "two protocol" (Multipart/formdata over HTTP POST and
Application/IPP over ToBeDetermined) approach was presented
The ADs made it clear that one protocol must be chosen as "required"
The was strong encouragement from experienced IETF participants that
protocols where there is only one choice have succeed far better than
protocols which have multiple formats; we were encouraged to pick only
one protocol.
Harald A. had observed that we can define a mapping from
Multipart/formdata over HTTP POST onto Application/IPP over TBD, but not
vica versa.
Security
We should examine SASL (an I-D at draft 8) and the TSL I-Ds (which are
in for final call on April 25) as solutions to our security problem.
The goals for security are not clear yet; we are investigating
mechanisms that we might prototype to see what would be workable.
IPP URL format?
Much like the special URL format proposed for FAX, do we need a URL
format for "TBD"
Minutes from IPP WG in Memphis
Don's minutes have been forwarded to IETF already.

Carl-Uno will tell SD that we would like to accept the off campus
location for the Wednesday meeting of the IPP
