24. STOP_TIME = “N/A” Some products do not have “STOP_TIME” while “START_TIME” exists though.

25. Feedback to PDAP specification 10.7.1425

26. 1.DATA_ACCESS_REFERENCE should provide “Directory Reference” Especially for RESOURCE_CLASS=DATA_SET, DATA_ACCESS_REFERENCE should provide a reference to directory. Most of NASA PDS products can be accessed from internet, and their URLs is structured by the name of “DATA_SET_ID”, which means that the directory name of DATA_SET_ID is convenient for users. The huge archived file including whole files of “DATA_SET” is unrealistic. DATA_SET_ID is convenient for users. The huge archived file including whole files of “DATA_SET” is unrealistic. 10.7.1426 Ex) If DATA_ACCESS_REFERENCE shows directory, the following URL can be used: http://starbase.jpl.nasa.gov/archive/clem1-l_e_y-a_b_u_h_l_n-2-edr-v1.0/

27. 2.Ambiguity of Search Result for Time Input 10.7.1427 SQL1 can only search ‘Case 3’, but SQL2 can search between case 2,3,4,and 6. Which is better response as a search result ? Case 1 Case 2Case 4 Case 5 Case 3 Case 6 SQL1: SELECT * FROM PRODUCT WHERE START_TIME >= ‘a’ AND STOP_TIME <= ‘b’ Case 1 Case 2Case 4 Case 5 Case 3 Case 6 START_TIME:aSTOP_TIME:b SQL2: SELECT * FROM PRODUCT WHERE STOP_TIME >= ‘a’ AND START_TIME <= ‘b’

28. 3.Ambiguity definition of RESOURCE_CLASS OUTPUT For example, DATA_SET has sometimes several instruments, and multiple targets: The DATA_SET_ID “CLEM1-L/E/Y-A/B/U/H/L/N-2-EDR-V1.0” has the following instruments: 1.ULTRAVIOLET/VISIBLE CAMERA 2.B STAR TRACKER CAMERA 3.LIDAR HIGH-RESOLUTION IMAGER 4.LONG WAVELENGTH INFRARED CAMERA 5.NEAR INFRARED CAMERA 6.ULTRAVIOLET/VISIBLE CAMERA The PDAP version 0.3 document does not describe the detail for the output, which may cause the inconsistency between the different implementations.

30. Concept of ATTRIBUTES In “PDAP version 0.3”, RESOURCE_CLASS can be specified. The member of this RESOURCE CLASS is in the followings: - DATA_SET - PRODUCT - IMAGE PRODUCT - FLYBY PRODUCT - etc. IMAGE PRODUCT assume that the map-projected image, which should be “MAP PROJECTED PRODUCT.” FLYBY ATTRIBUTE can be defined when TARGET AND PRODUCT, which means MAP_PROJECTED_ATTRIBUTE and FLYBY_ATTRIBUTE are not exclusive.
