OpenStreetMap has an Editing API for fetching and saving raw geodata from/to the OpenStreetMap database — this is the entry page for the documentation. If you just want to embed a map into a webpage, you don't want this API. Use a Web Map Framework instead.

For quite some time now I've been thinking about the best way to create a mapping and local information site for the Isle of Man - what will become Mapping.im once ready. Currently it's a very bare, ugly site, so don't pay too much attention to it. Working with the Drupal content management system so much, I naturally thought of that as the way forward, largely because of its flexibility but also because it gives me a good head start in developing a site that can do all sorts of things already, without me having to implement them individually. I had jotted down some notes in the past about what I wanted out of a site, but never really got quite as far as implementation details. Then earlier this week I went to an old haunt of mine - an Irish bar by where I lived in the first few months of being here in Stuttgart - and sat down with my notepad and pen (both of which I carry at all times).
