PyWPS 1.0.0 released: GRASS goes Web

Today PyWPS 1.0.0 has been released by Jachym Cepicky. PyWPS (Python Web Processing Service) implements the OGC Web Processing Service (WPS) standard in Python programming language. It has been written with native support for GRASS GIS which allows for accessing GRASS modules via Web. Processes can be run asynchronously. By default, GRASS GIS is supported, other tools (R, GDAL/OGR, PROJ.4, …) can be configured, too.

A first demo application can be seen here: WUIW – a PyWPS AJAX Web Interface.
