---++ 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
[[http://www.ivoa.net/Documents/latest/SIA.html][Simple Image Access]] (SIA) and
[[http://www.ivoa.net/Documents/latest/ConeSearch.html][Simple Cone Search]] (SCS)
specifications.

SSA is now an IVOA Recommendation.  The most recent version of the document
can be found [[http://www.ivoa.net/Documents/latest/SSA.html][here]].

---+++ SSA update collaboration page
New minor version of the SSA v1.1 specification is being produced, including some minor fixings.
