Hi Quim,
which are the most important technical topics
How we can support users in WP and OSM for tagging/linking objects from WD, WP, Commons and OSM together. (online tool, JOSM, ...)
Example: OpenSeaMap shows nautical infrastructure like harbours and lighthouses in the chart and would like to link it to WP and Commons. Therefore we look for a structure and a work flow.
Also it would be nice to show OpenSeaMap charts in WP-articles around sea, rivers, water sport and shipping affairs (slippymap).
Best regards, Markus
