We report progress on a new Web service for automated supervised object classification, which is being implemented in a collaboration between the GAVO {http://www.g-vo.org} and AVO{http://www.euro-vo.org} projects. The new service will eventually carry out the following steps: An input list of sky-positions is used for querying multiple distributed catalogues covering different wavelength ranges. The sources returned are spatially matched using a statistical method, and a list of observational spectral energy distributions (SEDs) is assembled. Model SEDs are prepared using a library of theoretical spectra. The observational SEDs are submitted to a statistical classifier that uses the model SEDs for photometric template matching. For each observational SED the best-matching model SEDs are identified. - A science case has been selected for testing the capabilities of this Web service.
