Ideally, the metadata DB system which can deal with arbitrary
metadata is the best but
• default setting of DSpace is for Dublin Core metadata format,
• IUGONET Common metadata format has deeper tree structure
than Dublin Core metadata format.
The integration analysis by using
various kinds of observational data
is necessity for investigating the
mechanism of long-term variations
in the upper atmosphere. However,
there are no way to cross-search
their DBs which are distributed over
many research institutes in Japan.
For resolving this inconvenience,
we build the Metadata DB in order
to cross-search their DBs.
Collaboration by using OpenSearch
Issues:
Global Observation Networks
•Observational DBs are distributed.
•To find out & collect many kinds
of data is difficult.
IUGONET provide the analysis software.
• Metadata which includes location information (e.g., URI) of
observational data is sent to the analysis software via OpenSearch.
Combine DBs
on metadata level
Hurdle of the
interdisciplinary
study
•The analysis software downloads observational data by using the
location information.

Metadata Format & Customization Points
We defined the IUGONET common metadata format which is
based on the SPASE Data Model [1]. Basically the metadata
includes URI of observational data, start & end time of
observation, spatial coverage of observation and so forth.
