The openlayers folder contains versions of the openlayers plugin for dokuwiki, the geotag plugin contains the geotag plugin, the (experimental) spatialhelper plugin is in the spatialhelper directory.
The current, most up-to-date, stable, version is the version without a version number.
SNAPSHOT versions are build from trunk but may not be of the same revision, ie they are not automatically updated after each commit
