RE: [EXTERNAL] Fwd: Protocol for requesting private data?

Provide specific parties permissioned/encrypted access to semantic data by type? Oh boy, Identity Hubs surface again, like the white whale I have so long chased. To butcher a quote from another famous person who held the designation of captain in his younger years: "As certain as night succeeds the day, without Hubs we can do nothing definitive, and with them, everything honorable and glorious!" - George Hubington

Sorry if this is the wrong place to ask...

I'm looking for details on how to use SSI to request access to 'private' data from a controller. Specifically, I'm thinking about nuggets of data that I don't want to put in plain text in a DID document.

My example is shoe size. An online shoe shop wants to know my shoe size to taylor my browsing experience.

Are there specific / concrete proposals on how to negotiate this data?


Many thanks,
Dan.
