A need has been identified to allow clients to access the same content using different \"Coordinate Reference Systems (CRS)\".  This is a potential dimension of content negotiation. Others in the spatial domain would include geometry type (point, bounding box, outline polygon, complex polygon with islands and holes) and spatial precision. Temporal dimensions are also relevant - last known position, version no etc.\r\n\r\n## Existing approaches\r\nHTTP Content negotiation already uses dimensions of media-type+encoding and language. Profiles (views) is another fairly common case.\r\n\r\n## Links\r\nhttps://github.com/w3c/sdw/issues/1058\r\n\r\n## Requirements\r\nProfile negotiation mechanisms must support or safely co-exist with negotiation over other dimensions of data organisation.\r\n\r\n## Related use cases\r\n\r\n## Comments\r\nRaised by @larsgsvensson in Profile Negotiation sub-group - and we felt that this requirement was not captured and a Use Case was required.\r\n\r\n---\r\n"},"comment":{"url":"https://api.github.com/repos/w3c/dxwg/issues/comments/410970248","html_url":"https://github.com/w3c/dxwg/issues/311#issuecomment-410970248","issue_url":"https://api.github.com/repos/w3c/dxwg/issues/311","id":410970248,"node_id":"MDEyOklzc3VlQ29tbWVudDQxMDk3MDI0OA==","user":{"login":"lvdbrink","id":7943515,"node_id":"MDQ6VXNlcjc5NDM1MTU=","avatar_url":"https://avatars3.githubusercontent.com/u/7943515?v=4","gravatar_id":"","url":"https://api.github.com/users/lvdbrink","html_url":"https://github.com/lvdbrink","followers_url":"https://api.github.com/users/lvdbrink/followers","following_url":"https://api.github.com/users/lvdbrink/following{/other_user}","gists_url":"https://api.github.com/users/lvdbrink/gists{/gist_id}","starred_url":"https://api.github.com/users/lvdbrink/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/lvdbrink/subscriptions","organizations_url":"https://api.github.com/users/lvdbrink/orgs","repos_url":"https://api.github.com/users/lvdbrink/repos","events_url":"https://api.github.com/users/lvdbrink/events{/privacy}","received_events_url":"https://api.github.com/users/lvdbrink/received_events","type":"User","site_admin":false},"created_at":"2018-08-07T08:02:52Z","updated_at":"2018-08-07T08:02:52Z","author_association":"CONTRIBUTOR","body":"> @lvdbrink is, i think, reiterating the point I was trying to make, in that we shouldnt expect or require every domain to make up its own approach to negotiation over variable aspects of data distribution.\r\n\r\nYes, exactly."}}
