4. Defini7on…
 A Virtual Observatory (VO) encompasses all forms of
network tools, databases and websites that are
utilized for collaborative research.
 From
Oct.
2010
NSF
will
require data management
plans as part of all NSF funding proposals.
“This addresses the need for data from publicly-funded
research to be made public” (NSF Deputy Director)

5. Space
Data
challenges…
 Technical
innovation
means
increasingly
sophisticated
instruments
are
being
proposed
and
deployed
 Data
volumes
are
growing
exponentially
 Future
experiments
are
expected
to
generate
upwards
of
1015
Bytes
of
data
!
 Data
management
challenges
are
numerous
 Data
is
stored
in
different
formats
across
heterogeneous
computer
environments
 Standards
where
they
exist
are
still
rapidly
evolving
 Appropriately
defined
meta-­‐data
is
needed
to
find
and
access
relevant
“physical”
data
(e.g.,
SPASE)
 Collaboration
is
key
to
making
advances
in
space
science

6. CSSDP

(using
CANARIE’s
high-­‐speed
network)
 A
gateway
to
make
data
available
to
other
researchers
 An
environment
to
host
common
analysis
tools
 A
place
to
collaborate
with
research
teams
 A
workflow
engine
to
simplify
research
tasks

8. Metadata…
 Metadata
 Description
of
data
sets
or
other
resources
 Allows
catalogue
and
search
of
data
 CSSDP
follows
NASA/SPASE
XML
standard
 Usually
generated
from
data
file
path/name
 Metadata
includes
 Date/Time
 Project,
Instrument,
Observatory
 Data
Stream
 SPASE
XML
-­‐
resource
then
can
be
shared
over
internet
