On Saturday June 8th, I was attending the App.net hackathon in San Francisco (the article is coming soon…) and I saw a presentation about a way to standardize the parameters passed from app to app via iOS URL Schemes, called x-callback-url

If you want to learn more about this, the specification is here : http://x-callback-url.com/specifications/

And here is the associated blog where I learned, among other things, that Tumblr integrates x-callback-url : http://x-callback-url.com/blog/

You can also follow the project via Twitter : @xcallbackurl

I will certainly try to use this next time I am struggling with URL schemes, just to see if the standard is efficient and comprehensible.

What do you think about it ? Do you know other people trying to standardize inter-app communications ? Do you or would you use it ?
