Maybe the executive team at IRIS can have this conversation about what the best way to do this. Keep in mind student protection issues. A PASSCAL database exists but may be underutilized, again need to be visible via Google. How can we do a better way of accessing our data sets (newly derestricted or currently restricted).

Brief Meeting Summary
The Fall DSSC took place at Lamont Doherty Earth Observatory in Palisades, New York on April 2-3, 2015. Five members participated in person, 2 members participated for the entire meeting via videoconference and two members had other obligations and did not participate in the meeting.
The status of Action Items from the previous DSSC meeting was presented and discussed. (http://www.iris.edu/hq/meeting_report/ds/2015/04/)
Several projects to improve efficiencies of the DMC were discussed and endorsed by the DSSC. These included the preproduction of M quality data to be stored in the DMC RAID systems instead of doing it dynamically as it is currently done. Additional projects related to the development of a new way to index the archive was discussed as well as an update on the progress toward the elimination of Oracle from DMC operations.
ACTION ITEM: The DSSC endorses the concept of creating an M or best version of waveforms for the IRIS RAID systems to reduce the processing overhead in the current system. All original data will be retained for later reprocessing if problems are discovered and all current business rules will remain in place such as IDA M data will only contain data that has gone through IDA Quality Control once the Q version is available.
A discussion related to rescoping the DS budget to meet a decreasing budget. The rescoping plan was endorsed.
The DSSC discussed a policy to manage Large-N datasets and this resulted forwarding a data policy to the IRIS BoD for consideration. The Large Data Temporary Deployment Data Policy (LTDT) was finalized by the DSSC and forwarded to the board.
A discussion took place about a DS project that will begin in SAGE Year 3, and the Research Ready Data Sets (RRDS) concept was supported. This effort will allow pre-filtering of data at the DMC that meets a requestor’s constraints based upon MUSTANG metrics.
The DSSC was briefed on the progress made within the FDSN related to the generation of DOIs for seismic networks. This effort can be viewed on the FDSN pages found at http://fdsn.org/networks/ .
The DSSC was updated on the concept of Federation of FDSN Data Centers and IRIS’ efforts on developing a federated system that would be further discussed at the FDSN meetings to be held in conjunction with the IUGG in Prague in 2015. More information can be found at http://www.fdsn.org/webservices/datacenters/
The DSSC was also briefed on the development of a new Message Center being developed at the DMC to better communicate with the users of IRIS broadly but specifically the DMC. This system will allow users to better select the threads of information they are interested in.
A status report from the IRIS Director of Data Services was presented. This was followed by reports from DS nodes including IDA DCC, ASL DCC, the PIC, a report from the IDA DCC, a report from ASL, and a report from the PIC.
The DSSC had a telephone conversation with the SAGE NSF Program Director, Gerg Anderson. Greg was briefed on the LTDT policy concept. Greg commented on the PREEVENTS initiative within NSF and stated he did not see this as potential funding to augment activities of IRIS DS.
Reports from the QA working group and the Data Products working group were presented.
The DSSC spent considerable time identifying those things they felt were IRIS DS Foundational facilities and services as well as things they felt were frontier areas of efforts that should be pursued by IRIS DS. Integration across IRIS directorates was also discussed in areas where cooperation was at a high level.
Action Item: Prepare a 1 page budget rescoping impact statement.
Discussions related to the impact of regional network data on the IRIS DMC took place and requests for more information concerning this were articulated.
A SAGE Year 3 budget was presented and discussed by the DSSC.
Action Item: The DSSC recommended forwarding the proposed budget to the IRIS BoD for consideration as presented.
