ISWA - HAPI Server
ISWA supports the HAPI Data Access Specification (version 2.0) for delivery of time series
data. Currently ISWA - HAPI includes all data resources/parameters that are shown in ISWA's super timeline cygnet. More timeseries data are planned to be available via ISWA-HAPI in the future. A HAPI compliant server consists of the following 4 REST-like endpoints that will
respond to HTTP GET requests.
- capabilities describe the capabilities of the iswa hapi server
- catalog list the datasets that are available; each dataset is associated with a unique id
- info obtain a description for dataset of a given id; the description defines the parameters in every dataset record
- data stream data content for a dataset of a given id; the streaming request must have time bounds start.min, start.max
