raid on the Medway". It shows two flotillas, it indicates how they move. It does not show anything happening of the other side of this battle. It does not show positions.
A sprite is a two-dimensional image or animation that is integrated into a larger scene. It can be put on a map. Picture this, the same map of the raid on the Medway and two little sprites moving in time along the indicated lines.
Technically it is not much of a challenge. It becomes interesting when it starts moving on a real map, an OpenStreetMap for instance. Add the moments when we have images that show scenes of a battle, an occurrence and we get something that becomes relevant.
Technically it seems doable. It seems like a challenge that brings together the parts that already exist. It will be really exciting when it brings Wikidata, Commons, OpenStreetMap together. It will help us explain about events. It is part of sharing the sum of all knowledge.
