Many people from a wide range of organizations have participated in the SPASE consortium. The origanizations include:
- Augsburg College
- California Institute of Technology (CalTech)
- Centre de Donnèes de la Physique des Plasmas (CDPP)
- Istituto Nazionale di Astrofisica (INAF)
- Japan Aerospace eXploration Agency (JAXA) - STP/Ehime
- Japan's Inter-university Upper atmosphere Global Observation NETwork (IUGONET)
- Jet Propulsion Laboratory (JPL)
- John Hopkins University/Applied Physics Laboratory (JHU/APL)
- George Mason University
- Goddard Space Flight Center (GSFC)
- National Aeronautics and Space Administration (NASA) HQ
- National Oceanic and Atmospheric Administration (NOAA)
- NOAA's National Geophysics Data Center (NGDC)
- Rutherford Appleton Laboratory (RAL)
- Stanford University
- Southwest Research Institute (SwRI)
- University of California, Los Angeles (UCLA)
1998 - ISTP
The SPASE effort has its root in the data handling
session of the ISTP workshop held at RAL in 1998, when on
Sept 26 a resolution was passed calling on the "larger
data centers" to "do something" to make data more
2001 - AISRP
Early in 2001 a breadboard interoperability test bed was
implemented between NSSDC and CDPP/CNES, and later that
year, in response to an AO from NASA AISRP ROSS (Applied
Information Systems Research Program, Research Opportunities
in Space Science), a proposal entitled "A Space Physics
Archive Search Engine (SPASE)" was submitted jointly by
NSSDC, SwRI, RAL and CDPP.
2002 - Grassroots
While this proposal was not funded a volunteer effort
continued and attracted broader participation. It was
recognized that a data model was needed to establish an
"interlingua" to share resources across the entire space
physics domain. The goals of this effort were defined in
late 2002 and the new moniker of Space Physics Archive
Search and Extract (SPASE) was adopted.
2003 - Open Community - NASA LWS
In 2003 the effort was organized as an international
consortium with an open invitation for anyone in the
community to participate. U.S. participants in SPASE were
funded by NASA in July 2005 which helped accelerate the
2005 - Release 1.0
In release of the SPASE data model. November 22, 2005.
2006 - Release 1.1.0
In response to community feedback, the data model was
improved. In that same year NASA solicited proposals to establish
thematic virtual observatories for the heliophysics
community and SPASE was adopted as the metadata standard to
enable interoperability. Released August 31, 2006.
2007 - Release 1.2.0
Based on feedback from the community and from the selected
virtual observatories the data model was further refined and
version 1.2.0 was released in May 22, 2007.
2009 - Release 2.0.0
After a period of use in NASA's VxOs the model was
streamlined and enhanced to support a wider range of
resources. Released April 15, 2009.
2010 - Release 2.1.0
Additions were made to support a wider range of phenomenom types
and particle attributes. Some grammar changes were made, most important
was changing "Qualifier" to "Component" which more accurately represented
the concept. Released March 18, 2010
2011 - Release 2.2.0
Added "Excel" as an allowed format, improved Render Hints, updated definitions,
and added support for referencing resources in cloud storage. Additional terms
were included to improved the ability describe solar data. Released January 6, 2011.
2011 - Release 2.2.1
Added "core", "halo", "strahl" and "superhalo" to the dictionary and to "Qualifier".
Released August 18, 2011.
2014 - Simulation Extensions 1.0.0
Release the IMPEx developed Simulation Extensions.
Released May 19, 2014.
2015 - Release 2.2.3
Fully integrated support for extensions.
Released May 31, 2015.
2018 - Release 2.3.0
Support for DOI and HAPI.
Released May 31, 2018.
2018 - Release 2.3.1
Support for wider range of wave and particle data types.
Released November 11, 2019.
2018 - Release 2.3.2
Support for Instrument groups and wider range of roles for contacts.
Released October 15, 2020.
