I love it when technology you've been backing finally start to mesh together to form a better experience. Well in that same vein, comes dataportability.org – the open standards stack for the ubiquitous sharing and remixing of data.
All the expected standards are there including OpenID and RSS. Theres a nod towards inclusion of ubiquitous microformats like hcard and xfn which is a good idea. I would have liked to have seen FoaF and ATOM but Opml is also included which is used wide enough for it to be included. Then we have the newer kids on the block. Oauth, APML and Yadis.
I learned quite a lot about Oauth while in Berlin so can certainly give it the thumbs up now. Its basiclly like Open ID for data exchange. The best example of how it works is like how Flickr allows 3rd party applications to talk to it by authenticating them via the user first. So for example you could allow a upload tool read and write to your flickr but only let Moo.com read from them. APML i'm a large backer of from day one, when I discovered it in Particls/Touchstone (at the time). Yadis is new to me but I see its made up of things like LID and OpenID. Its bascilly a way to tie together your identies online. So you can specify openID and lightweight ID in the same file. I'm sure you could even add things like Jabber ids and other type things in the future.
Anyway, all these specs are very open and worth palying
