An information model for describing the elements of the heliophysics data environment, and a set of resource types which can be used to describe data along with its scientific context, source, provenance, content and location. It is designed to support a federated data system where data may reside at different locations and may be seperated from the metadata which describes it. The preferred expression form is XML.
The Space Physics Archive Search and Extract (SPASE) effort is implemented by the SPASE Consortium which is composed of representatives of the international Heliophysics data community. The Current Release of the data model (2.2.2) was updated in October 2012.
A web-based editor for generating SPASE descriptions.
The SPASE website's list of tools for working with SPASE metadata and the SPASE framework.
The National Space Science Data Center's registry of SPASE-described space science mission data.
The SPASE website's list of systems that use SPASE compliant metadata to enable search services.
