The vector tile schema has been developed by Klokan Technologies GmbH and was initially modelled after the cartography of the CARTO's Positron basemap with permission from CartoDB Inc. The vector tile schema has been refined and improved in cooperation with the Wikimedia Foundation and is heavily influenced by years of Paul Norman's experience of creating maps from OpenStreetMap data.

Products or services using maps derived from OpenMapTiles schema need to visibly credit "OpenMapTiles.org" or reference "OpenMapTiles" with a link to http://openmaptiles.org/.
For a browsable electronic map based on OpenMapTiles and OpenStreetMap data, the credit should appear in the corner of the map. For example:

For printed and static maps a similar attribution should be made in a textual description near the image, in the same fashion as if you cite a photograph.
