This specification defines a protocol for retrieving spectral lines from different spectral line databases through a uniform interface.
The interface is meant to be reasonably simple to implement by service providers.
A basic query will be done in a wavelength range for the different services. The service returns a list of spectral lines formatted as a VOTable.
Thus, an implementation of the service may support additional search parameters (some which may be custom to that particular service) to more finely control the selection of spectral lines.
The specification describes how the search on extra parameters has to be done, making use of the support provided by the Simple Spectral Line Data Model, SSLDM
