The Web Processing Service (WPS) is just about to become an official standard of OGC (status June 2007). It allows performing geo-processes on the web based on a simple XML communication encoding. The 52° North WPS developed and provided by the 52° North open source initiative (www.52north.org) is the only implementation written in Java, which covers all aspects of the current specification.

The proposed talk will first give an overview about special features of the current specification and some changes, which will come along with the new WPS version 1.0.0 like SOAP/WSDL support. The main part of the talk will focus on the architecture of the 52° North WPS and the most important features of the 52° North WPS (such as asynchronous processing, raster support, new parsers and an enhanced build process using apache maven). Finally the talk will discuss some on-going research developments at 52° North towards modeling Geoprocessing Workflows(GPWs), enabling the WPS to offer complex GPWs formalized in BPEL as simple processes and the integration of desktop GIS (e.g. GRASS) geoprocessing capabilities in 52° North WPS.
