Change Details

Possible data sources are: * Processed, cached OSM dump (this is how geoshape works) * Processed, cached Wikidata dump ([[ https://www.wikidata.org/wiki/Property:P625 | P625 ]]). This would be new development. * SPARQL query by QID. * wbentities query Questions: - [] What are advantages and disadvantages of each? - [] Which data set is more complete? (Determine how many coordinates are associated with a QID on OSM vs. how many wikidata items have coordinates? - [] Find out how the dataflow (wikidata -> OSM) is currently working (for GeoShapes): Do they have the same data? In which direction does the data flow? Does it happen automatically, and if so on what schedule?
