The Space Physics Data Markup Language (SPDML)
is being developed using eXtensible Markup Language (XML) to provide a standard
method for expressing Space Physics data sets. SPDML is being utilized in
a prototype system to provide a standard method of data querying enabling
multi-instrument comparisons to Thermosphere,
Ionosphere, Mesosphere, Energetics and Dynamics (TIMED) data and tracing
the Sun-Earth connection. As a test-bed, we are using data from the NASA TIMED
spacecraft and ground-based Super
Dual Auroral Radar Network (SuperDARN) radars.
SPDML describes:
- structure
- semantics
- content
of any space physics data set in any data format.
This allows the construction of metadata from existing data sets in both
standard (NetCDF,
CDF,
ASCII, etc.) formats and mission specific formats to be processed. Commercial
off-the-shelf search engines can then be used to discover and access multiple
distributed scientific resources, providing easy cataloging and retrieval
of Space Physics data as well as providing a multi-instrument comparison
to TIMED data.
