Every tool published on these pages may be also accessed programmatically via XML Web Services. We recommend you try the VO way and test drive our webservices and take advantage of them to automate (for example) the upload of large amount of spectra. Read the tutorial here to get started.

You can learn more about web services from the NVO Summer School proceedings: http://www.us-vo.org/summer-school/2004/proceedings/index.cfm
If you want to publish your own spectra in Spectrum Services depending on your needs, you may install the MySpectrum package at your organization and build a spectrum collection yourself. MySpectrum is a cross-platform implementation of the Spectrum Web Services that runs on Windows using the .net framework (usually part of the OS) or on Linux using the mono framework. On Windows you can store the spectra in Microsoft SQL Server 2005 (which has a free edition called SQL Server Express) or MySQL. On Linux the only option right now is MySQL, but more servers are going to be supported in the future.
In order to use mono to program against spectrum services, you are required to install the latest stable mono version from source. Unfortunately many mono bugfixes are only available this way, the binary packages are usually out of date. For more information about downloading the source code and compiling it refer to the mono webpage at http://www.mono-project.com.
You can download the latest package from our download area.
Spectrum Services implement the IVOA Spectrum Data Model v1.01, it's XML and VOTable Representation and the IVOA Simple Spectral Access Protocol v1.01 using VOTable v1.10 (see http://www.ivoa.net/Documents/ for details and references.)
