Last year I bough a Nokia N95. This is a high-end smart phone with many media-features built-in. One of the features lets you 'blog' and upload photos and videos from the mobile directly to an online blog or photo service, like Flickr and Vox. That's very nice and all, but I have my own photo album system. Wouldn't it be great if I could upload photos from my phone directly to my own album? Yes it would! So I start digging.
Nokia's Share Online application
Nokia released the Share Online ↑ tool for a large number of their Symbian-powered phones, including the the N95. In fact, the N95 comes pre-installed with this tool.
The Share Online blogging software handles the accounts and services used for blogging. This is NOT Nokia's own LiveBlog, but third-party services like Flickr and Vox. With the help of a HTTP debugger proxy Fiddler ↑ (great tool, and free!) I found that the Share Online application uses a form of the AtomPublish protocol. More specifically, the Atom protocol developed by Six Apart ↑.
The best thing is that the Share Online application lets you add and manage new services, based on this protocol.
