Metadata ResourcesHELIO has gathered an assortment of types of metadata in order to provide a rich search environment and facilitate the identification of interesting events and the search for data. The metadata are managed by the different services and collectively can be used to address complex science use cases. The services are normally accessed through their Web Service interfaces when being orchestrated but there are also GUIs available.
Identify interesting Events and PhenomenaThe Heliophysics Event Catalogue and Heliophysics Feature Catalogue are designed to help identify interesting events and phenomena and determine the times and locations of their occurrence.
See the HFC Contents for the summary of the types of feature that have been processed and the time ranges that they cover.
Identify and Locate suitable ObservationsThe Instrument Capabilities Service (ICS) and Instrument Location Service (ILS) allow the user to discover whether there could be relevant observations of the phenomena available.
The pointed-instrument tables of the Unified Observing Catalogue (UOC) support this activity. Coupled with a propagation modelling capability, the metadata services allow the user to identify the onset of a phenomenon and then track it as it moves out through the Solar System.
Finally the Provider Access Table (PAT) of the Data Provider Access Service (DPAS) provides information to the system that allows it to identify where particular datasets can be found; the planetary tables of the UOC help resolve access to data in the ESA and NASA planetary archives.
