3-1055 (Use of Compression in PDS Archives)

Before any discussion on the specifics of the SCR, Anne Raugh said
that as a policy, this is an MC issue that we, the Tech Session, don't
have the authority to decide and therefore shouldn't be wasting our
time on.  She did not believe we should even be discussing a draft
policy for the MC to consider.

Todd King agreed and said that Elizabeth had not received direction
from the MC to come up with a policy on compression, and therefore
should never have even written a draft.

Elizabeth responded that MC has made it Elizabeth's highest and only
priority to get the JPEG 2000 issue resolved and that the tech folks
had previously directed the EN to produce a data compression policy
(as a separate SCR) as the Tech Session couldn't make decisions about
the JPEG 2000 SCR without a compression policy in place.

Todd agreed.

Susie suggested that we either:
 (1) Agree to go ahead with the compression policy, or
 (2) Agree to table the policy and proceed with the JPEG 2000 SCR
 without a compression policy in place.

Anne/Todd stated that JPEG 2000 SCR should be decided by tech folks
strictly on the basis of its technical merits, and leave the decision
of whether or not to permit compression in general up to the MC.

Proposal to table the compression policy and move forward with the
JPEG 2000 SCR without a data compression policy in place:

The SCR was voted on:
ATM - Lyle Huber - yes
EN - Steve Hughes - yes
GEO - Susie Slavney - yes
IMG - Myche McAuley - yes
NAIF - not present
PPI - Todd King - yes
Rings - Mitch Gordon - yes
RS - Dick Simpson - yes
SBN - Anne Raugh - yes

Chris: We've been going in a loop on this.  Let's make certain that
everyone agrees that we're not going to come back next time and demand
a policy is in place before continuing with the JPEG 2000 SCR.

Mitch: The meeting minutes should indicate that we are going ahead
with evaluation of JPEG 2000 on the
basis of some technical issues, but there are higher level policy
issues that need to be resolved by MC such as when, if ever,
compression should be used.

Todd warned that PPI would be evaluating the merits of JPEG 2000 based
on his own criteria and that those criteria would probably be along
the lines of the rules laid out in the draft policy.

Elizabeth asked how can the TechSession decide on an issue when we
don't have an agreed upon set of criteria against which to evaluate
it.

Todd said each node can have its own criteria.

Elizabeth indicated that she will table the data compression policy
(for the time being) and will focus on having the JPEG 2000 SCR ready
for discussion before the Tech Session scheduled for next week.

Meeting ended.
