Like in 2009, I attended the OSGeo Code Sprint (and Hacking Event) in Bolsena, Italy during June 6-12, 2010. For one week developers from various Free and Open Source for Geospatial (often abbreviated as FOSS4G) projects get together in a monastery near Bolsena for code sprints, cross-project collaborations, presentations and geo-hacking in general. This all takes place in a relaxed atmosphere mostly outside. Thanks to the cook Enzo we enjoyed the Italian kitchen. This year I did some work on GeoNetwork and more in depth on INSPIRE FOSS, a new FOSS project I initiated to support the development of INSPIRE using FOSS. In Bolsena I worked closely together with the deegree lead developers Markus Schneider and Andreas Schmitz from lat/lon. At the spot we were able to construct a demo that showcased the power of the upcoming deegree version 3 WFS/WMS in supporting INSPIRE Data Themes. Meeting project leads and developers and following presentations from other projects like GeoServer, deegree and MapBender was really worthwhile. Like last year I have made a video impression you can see below or on YouTube.
