Many have tried - very recently - and seemingly stalled or failed at creating something like this with wide adoption, most notably Tim Berners-Lee with the SOLID protocol

The roadblock is always getting major tech companies to accept it as a valid means of accessing user data.
The amount of times I've heard about SOLID on NPR or other popular mainstream newscasts only to garner little to no support is astounding. Definitely take note where others have seemingly failed here because it's an uphill battle.
