There is a new mapping initiative from the major tech firms aimed at standardizing the API for open map data.
It sounds like the Overture Foundation is unhappy with the OpenStreetMap data structure and wants to clean things up, saying, “Open map data can lack the structure needed to easily build map products. Overture will define and drive adoption of a common, well-structured, and documented data schema to create an easy-to-use ecosystem of map data.”
