Data Models for Spectral Data

Here we have various efforts to model 1D spectra , spectra with photometry and spectral timeseries . The corresponding protocol that uses Spectrum medata is the Simple Spectral Access (SSA) protocol ,

Implementations description

SSA is considered as the main reference implementation for Spectrum DM . It is widely implemented in the VO ( check with VO registry)

Document Revision

After the Garching Interop meeting in Nov 2009, some discrepancies in the Utype lists were reported between Spectrum DM document and the SSA protocol document. See the request changes summary page here.
