Collaborative Page for SSA Interface

The Simple Spectral Access interface (SSA) defines a uniform interface to simple 1D spectra, with extensions planned also for time series, and SEDs. It shares many similarities with the Simple Image Access (SIA) and Simple Cone Search (SCS) specifications.

• Latest draft of the SSA query interface (V0.97 WD) (most of this document is actually at the V1.0 WD stage, e.g., the queryData operation request parameters and request response).
• Latest draft of the Spectrum data model (V1.0-rc2 WD)
• Reference SSAP Services. These provide a reference example of the current query interface and query response.
• A spreadsheet summarizing the overall SSAP and Spectrum data models.
