NextGIS not only uses opensource software but also invests resources in it’s development and support.
We’ve added TinyOWS to OSGeo4W installer. TinyOWS is a small and fast WFS-T server that implements latest WFS-T standard, as well as related standards such as Filter Encoding (FE). Compilation, packaging and testing was done by our specialists, they will also carry out package maintenance in the future.
NextGIS also maintain another package in OSGeo4W — matplotlib.
We will continue to support these packages and hope to take the initiative and support other packages in OSGeo4W that we use, but which are yest missing in OSGeo4W.
