GeoServer, a Java Server implementing WMS, WFS, WCS and WPS makes available a
GeoPackage plugin that can handle both Tiles and Features. It can be the
source of data for GeoServer, serving the data in the GeoPackage as a OGC web standards. GeoServer can also
generate GeoPackages in a variety of ways (WMS or WFS output, or a WPS process). The plugin is still a 'community module', so it is unsupported and only available as a
nightly build in the community section (download
2.5.x and
2.6.x)
