<H1>Data Models for Spectral Data </H1>

<br/>

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 ,

   * Spectrumv1.03 IVOA Recommendation 2007-10-29 

   ++Drafts in preparation 
   * Spectrumv1.2 draft 2011-02-17  
    http://vo.cfa.harvard.edu/dm/docs/spec/SpectrumDM-20110217.pdf 
   An extension of Spectrum DM in order to support Photometry metadata and time series is in preparation .

---++ 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 [[IVOA.SSA_v1_1][here]].

Updated version currently checked in the DM wg group available [[http://www.ivoa.net/internal/IVOA/IVOADMSpectraWP/SpectrumDM-20110118.pdf][below]]
