What we need is a universal standard way to store all of our personal data on our phone and share whatever is relevant at whatever company/government at the touch of a button.

Nor a secretary nor a doctor nor anybody should have to hand-type data that already exists digitally.

I'm so mind-blown that this doesn't exist yet that I feel maybe I should try and build it. I have tried building the next-best thing: OCR based form filling, but hard to get far as a solo FOSS'er.

" this doesn't exist yet"

We have a national health database in Finland called "OmaKanta" (which translates to MyDatabase or something like that). It's not perfect but at least I can trust it with most of my health records, and it's accessible to all doctors working in both public and private sector.

Many healthcare provider organizations have standard HL7 FHIR APIs that patients can use to download their own chart records. There are a variety of apps that you can use to call those APIs.

Im talking about a standard GLOBAL way of sharing that exact same data AND all other personal data.

FHIR is a global standard.

I wonder if the Solid protocol might be helpful here? [0] I must confess I haven't toyed with it so far, but I am looking for an excuse to try it out.

Looks cool, but is more abstract/low-level than what I mean. Could maybe be used as a foundation for it though.

Problem: there are 19 competing standards

New problem: there are 20 competing standards

There are 0 standards for global sharing of all possible personal data. That I know of.
