Abstract
Web Services form a new, emerging paradigm to handle distributed access to resources over the
Internet. There are platform independent standards (SOAP, WSDL), which make the
developers’ task considerably easier. This article discusses how web services could be used
in the context of the Virtual Observatory. We envisage a multi-layer architecture, with
interoperating services. A well-designed lower layer consisting of simple, standard services
implemented by most data providers will go a long way towards establishing a modular
architecture. More complex applications can be built upon this core layer. We present two
prototype applications, the SdssCutout and the SkyQuery as examples of this layered
architecture.
