Interlinking OpenStreetMap and Wikimedia How to take advantage of URL interlinking to list and describe Geographical objects “ Where do you want to go to? Alice in Wonderland… ” Would you tell me, please, which way I ought to go from here?' 'That depends a good deal on where you want to get to,' said the Cat. 'I don't much care where —' said Alice. 'Then it doesn't matter which way you go,' said the Cat Motivation and Goal De Wikimedia en OpenStreetMap (OSM) organisatie en vrijwilligers delen heel wat principes. Het zou goed zijn als gemeenschappelijke projecten kunnen worden opgezet en ondersteund. Wikipedia, Wikidata en Wikimedia Commons kunnen worden gebruikt samen met OpenStreetMap om onderlinge linken vast te leggen en te tonen. Wikimedia objecten kunnen worden gekoppeld in OpenStreetMap via node tags (labels, key-value pairs). Dit laat toe om nog meer metadata, beschrijvingen en multimedia te verzamelen en te documenteren over geografische objecten. OpenStreetMap interactieve kaarten kunnen worden getoond in Wikipedia-artikels. Wikidata kan doorverwijzen naar OSM objecten.
