The SPASE Data Model consists of an exclusive 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.
While the data model is neutral on how to it may be expressed, the preferred expression form is XML. There are XML Schema documents which can be used to generate and validate SPASE compliant XML documents.
There are tutorials and other information available at the SPASE School.
SPASE Base ModelThe Resource Types currently in the base data model are:
Each of these elements is broken down into sub-elements that provide sufficient detail for adequate description of data sets. The Resource Types NumericalData, DisplayData and Catalog are the resources used to describe Heliophysics data products. These data product descriptions reference the other resources which contain descriptions of the observatories, instruments, people, etc. that created the data products.
SPASE Simulation Extensions
The SPASE Simulation Extensions were originally developed by the Integrated Medium for Planetary Exploration (IMPEx) project, a European Union (EU) Seventh Framework Programme sponsored project.
The Resource Types currently in the simulation extensions are:
The simulation extensions also override the following classes in the base model:
Each of these elements is broken down into sub-elements that provide sufficient detail for adequate description of simulation models and generated data sets. Data product descriptions reference the other resources which contain descriptions of the observatories, instruments, people, etc. that created the data products. The resources are described using the terms from the SPASE Simulation Extension Dictionary along with terms from the Base model.
