The Simple Spectral Access (SSA) Protocol (SSAP) defines a uniform interface to remotely discover and access one dimensional spectra.

The current stable IVOA Recommendation is REC-SSA-1.1 (available from IVOA Documents Repository).

In the future it is expected that this standard will be superceded by extensions of the SIA2 and SODA standards. As a result this standard is remaining in DOC format rather than being converted to IVOATex.

Please use this repo to post issues about this specification for further revision.
