Abstract

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. This type of query, based in a spectral range search, could be too simple to obtain useful results for some services. For instance, in the case of theoretical spectral line databases, the number of lines returned, even for small wavelength ranges, could be huge. However, some services could implement some other extra search parameters to restrict the search or to score the line as per its probability within a certain physical conditions. How these extra search parameters can be handled by the protocol will be studied in this document.
