2-3 DMS RWG Approved RTCs for Rev B PR #TitleDescription 73542add "when requested" to DAN/ACK requirements The DMS requirement to send a DAN_ACK for calibrated engineering data should be conditional on the request for an ACK in the DAN revisions to Calibration Reference Data Archive requirements Clarification on “CRDS Web Service” requirement 74001receive ssr accounting reportDMS needs a level 4 FOS-DMS interface requirement to receive the SSR accounting report DMS Requirements for NIRSpec Pre-image NIRSpec scientists have requested that the NIRCam, or other, pre-image used to prepare the target catalog for a NIRSpec MSA observation be included with the proposal and archived with the science data.

2-4 DMS RWG Approved RTCs for Rev B PR #TitleDescription 74870Change DMS-166 verification method from analysis to inspection As we already have an operational SID system, this requirement can now be verified by inspection rather than analysis transfer DMS "Image Statistic Keywords" requirement to WSS The original motivation for adding these image statistics keywords to the FITS headers was to provide information to the Wavefront Analysis Software (WAS) to support validation of S/N in WFSC data during OTE commissioning. Currently thinking is that the proper way to implement validation of S/N in WFSC data is through an interactive preprocessor tool to augment the WSS instead of in the DMS Delete "DMS Lifetime" requirement DMS-66 is a flow-down from SOC-49, " S&OC Facilities Lifetime," which is also to be deleted. Both of these requirements are applicable to the S&OC facilities plan, not software requirements. Nov. 6, 2013S&OC Data Management System Design Review 3

2-5 DMS RWG Approved RTCs for Rev B PR #TitleDescription 76007Add SOC link to DMS "WFS&C Data Processing Rate" requirement DMS requirement WFS&C Data Processing Rate should link to two SOC parent requirements. In addition to the existing link to: Science Data Product Availability for Designated Visits, DMS-462 should also link to WFS&C Data Processing Time Add DMS requirements for individual S&OC SI capabilities There are individual SI capabilities listed in Section of the S&OC Requirements Document with no flow down to child requirements in DMS. Instead DMS has requirements which point to all SI capability requirements in Section of the SOC Requirements Document. DMS-192 and DMS-190 need to be expanded into individual requirements for each of the specified SI capabilities. Nov. 6, 2013S&OC Data Management System Design Review 3

2-8 NIRSpec MSA Requirement Changes Nov. 6, 2013S&OC Data Management System Design Review 3 Requirement changes in red text. See JWST-DMS-REQS PR Verification Method SDP Pre-image DANTest SDP shall receive electronic notification via a Data Availability Notification from PPS in accordance with the JWST S&OC Subsystems Interface and Control Document (JWST-STScI ) when a pre-image file is available for transfer Pre-image ACKTest SDP shall notify PPS via a Data Availability Notification acknowledgement in accordance with the JWST S&OC Subsystems Interface and Control Document (JWST-STScI ) when the pre-image file is successfully archived. Association Processing Associate Pre-image Data FilesTest The DMS shall associate pre-image files with the corresponding science data on an exposure basis. Data Analysis Tools FITSVerify Web ServiceTest The DMS shall provide a web service to PPS that will validate the FITS format and keyword content of a pre-image file. Ingest Archive Pre-image Data FilesTest The archive shall ingest and store pre-images as received from PPS. [DMS-672] Note: The image file must be supplied by proposer in FITS format, even if the data already exist in the archive. Storage Broker Store Pre-image Files On-lineInspection The storage broker shall store the pre-image file in the on-line cache component of the JWST data archive. Archive User Interface Retrieve Pre-image Data Files with Science DataTest The Archive User Interface shall provide an option to retrieve the associated pre-images with an archive retrieval request for science data. Distribution Pre-image File AccessTest Distribution shall provide direct access to pre-image files through a web service Pre-image Proprietary RightsTest The Archive shall enforce proprietary rights on the pre-image data files. Note: PPS will authenticate the proposal system user and pass that information to the archive. The archive will use the passed credentials to verify that the proposal system user is authorized to retrieve the pre-image data files.

2-9 Calibration Data Product Requirement Change Example Nov. 6, 2013S&OC Data Management System Design Review 3 Current DMS Requirements Generate Science Data Products Calibration Reference Data Generation The DMS shall generate Calibrated Science Data Products from Science Data for all supported modes of the JWST science instruments, as defined in section of the S&OC Requirements Document (JWST- RQMT , JWST-STScI ) under Science Instrument Capabilities. [DMS-192] The DMS shall generate Calibration Reference Data for use in calibrating Science Data from any of the supported modes of the JWST science instruments, as defined in section of the S&OC Requirements Document (JWST-RQMT , JWST-STScI ) under Science Instrument Capabilities. [DMS-190] Verification MethodInspectionTest Rationale for ChangeThere are individual SI capabilities listed in Section of the S&OC Requirements Document with no flow down to child requirements in DMS (see JWST-SOC-REQS PR 75545). Instead DMS has requirements which point to all SI capability requirements in Section of the SOC Requirements Document. DMS-192 and DMS-190 need to be expanded into individual requirements for each of the specified SI capabilities as listed in the table below. Current S&OC RequirementNew DMS Science Data Product RequirementNew DMS Calibration Reference Data Requirement Science Instrument Capabilities Generate Science Data Products Calibration Reference Data Generation This section defines the high-level science instrument capabilities to be supported by the S&OC Near Infrared Camera (NIRCam) NIRCam Imaging Generate NIRCam Imaging Science Data ProductsGenerate NIRCam Imaging Calibration Reference Data The S&OC shall support use of the NIRCam for imaging, including synchronous operation of the short- and long-wavelength focal plane arrays in each of the two NIRCam modules.
