As a developer integrating OpenStreetMap's standard map tiles into a web application, identify the official usage policy requirements. Specifically, what are the rules regarding how frequently I can request tiles, how long I should cache them locally, and the exact attribution text or link required for display?
Navigate to 'tile.openstreetmap.org'. Click the 'tile usage policy' link to go to the official policy page. Locate the 'Bulk Downloading' section to understand request frequency rules. Locate the 'Technical Usage Requirements' section to find local caching recommendations. Click the 'attribution link' to navigate to the detailed attribution guidelines. Identify the exact attribution text and linking requirements on the attribution guidelines page.
State that bulk downloading of tiles is prohibited and usage should be on-demand. State that tiles must be cached locally according to HTTP Expiry Header, or for a minimum of 7 days. Provide the exact attribution text 'OpenStreetMap' and confirm it should be linked to 'openstreetmap.org/copyright'.
