Strategy
• In present, DBs for HAYABUSA & SELENE have been managed
by each project team.
• We are planning to make a new JAXA’s Planetary DB (JPDB)
with the interoperability I/F in the internationalized manner
to unify the mission dependent DBs in JAXA.
• JPDB will cover all the JAXA’s planetary missions.
• To do above, JAXA would like to support the implementation
of the IPDA interoperability I/F.

A New Mission:
Telescope Observatory for Planets on
Small-satellite (TOPS)
TOPS was approved as the first
application of the small satellite
series of ISAS/JAXA.
The launch is scheduled in 2011.
2 telescopes of 30cm diameter are
onboard TOPS.
TOPS telescopes will be used
only for the planetary observations.
• Interoperability between Astronomical VO and
IPDA is required.
IPDA #2 [July 2007]
Current Status
• HAYABUSA DB
(Asteroid Itokawa touchdown)
– Hayabusa science data has been released in this April.
URL: http://hayabusa.sci.isas.jaxa.jp
– PDS conversion of Hayabusa dataset will be completed this fall.
– Hayabusa team is starting to build a test bed for the interoperability
with PDAP.
• KAGUYA [SELENE] DB
(Lunar orbiter)
– Kaguya will be launched on August 16.
– Kaguya team is examining the method to handle PDAP on their
Level-2 DB:
• Finish the early study for prototyping of interoperable system
for map product with PDAP
• Compile system requirement for interoperable catalogue system
with PDAP including security, authentication/authorization, etc.
IPDA #2 [July 2007]
Near Future Plan (within 1-2 years?)
• HAYABUSA DB
– The work to archive the science data in the PDS will be led by
Gwennie Furr (Arizona Univ.).
ISAS/JAXA will provide the necessary level-1 and level-2 data
for the PDS archive.
– After getting the budget, to coordinate prototype design for
interoperable catalogue system to search a specific Hayabusa data.
– Because of irregular body of the target, expression and search of
Map object data by “latitude-longitude coordination” may be not
suitable. It is necessary to discuss about this problem.
– Hayabusa scientists request test of data exchange between
Eros data of NEAR.
• KAGUYA DB
– After getting the budget, to initiate prototype design for interoperable
catalogue system to search a specific SELENE Level-2 product (Map
object data) and evaluate the results. (Wish to be done by the end of
next March)
– To coordinate with other ISAS/JAXA project (like as Hayabusa)
IPDA #2 [July 2007]
Next 5-10 years
• Japanese planetary science community has
strong motivation to the interoperability …
– Moon: international data exchange (2008-)
Venus: Venus Express – Planet-C (2012-)
– Mercury: BepiColombo – Messenger (2019-)
– Jupiter:
– Interoperability between other neighboring
research field
• TOPS Astronomy (2011-)
• BepiColombo Heliospheric Physics (2019-)

Interoperability Tasks
1. Solving Issue
SELENE catalog (metadata) in PDS like label in L2 Data is slightly
different from catalog for search and order in catalog DB (some
keyword (attribute) and value definition are different).
2．Task
• Need to develop
(1) Catalog interoperability software to interconnect between catalog
DB archived in PDS nodes / ESA PSA and SELENE L2 data base
through PDAP (Planetary data access protocol proposed by
PDS/PSA).
(2) PDS label development software to translate SELENE PDS like
label to PDS compatible PDS label which is detached to L2 data as
PDS label.
• Need to prepare
(1) Interoperable catalog system with PDS labeled L2 data archive

* Minimum catalog DB extracted from PDS label information (misison / instrument

* Extracted with JAXA’s defined metadata with XML format from PDS label
to import to PDS catalog DB to support multi missions in JAXA
IPDA #2 [July 2007]
Current Status
• Finish the early study for prototyping of
interoperable system for SELENE LISM L2
product (map product) with PDAP
– Metadata object mapping between SELENE
catalogue and PDS label object
– GUI I/F study for catalogue search
• Compile system requirement for
interoperable catalogue system with PDAP
including security,
authentication/authorization, etc.
• Define early WBS to design / develop
interoperable catalogue system

IPDA #2 [July 2007]
Next step
• To refine WBS to request the budget for
prototyping of catalogue interoperable system
with PDAP
• After getting the budget, to initiate prototype
design for interoperable catalogue system to
search a specific SELENE L2 product (Map
object data) and evaluate the results (Wish to be
done by the end of next March (by the end of
this JFY)
• To coordinate with other ISAS/JAXA project (like
as HAYABUSA)

(2003-)
IPDA #2 [July 2007]
Current Status
• Hayabusa science data has been released
in this April through a data distribution
server placed at ISAS/JAXA.
• We are building a system allowing access
to these data freely using a web-interface.

IPDA #2 [July 2007]
Concrete view
• The test which mounts PDAP to the Hayabusa
DB will be done.
• Two method will be considered.
The 1st one is to create I/F directory accessing
current Hayabusa DB.
The 2nd one is to create I/F accessing
Hayabusa DB converted to PDS-like format.
• Test bed for Hayabusa DB is cooperating with
test bed advanced for SELENE DB,
and considered increasing flexibility.
