Hello Sumana (and Brandon and Marc-André), There's been a mention of getting 2 copies of the "OSM database", one for the use of the production tileserver and the other for the use of Wikimedia Labs. Is this correct?
What I'd like to know is if this is the raw OSM database, which contains the raw OSM data that is suitable for editing, or a rendering OSM database suitable for rendering map tiles. The rendering database is usually loaded with a program like osm2pgsql[1] from raw OSM data that is either in XML or PBF file formats. The problem with a rendering OSM database is that this is optimized for rendering map tiles, which is excellent for the production tileserver. However, this database is (mostly) unsuitable for other purposes such as routing and (probably) spatial analysis. This may hamper possible use cases of developers on Wikimedia Labs wanting to explore using OSM data for various purposes.
