Shared Data Schemas

Since blockstack has the opinion that users should be able to move data from one app to another, has there been any effort to create a standardized shared schema for different data types that apps can build upon? ie, if you’re building a photo app, here’s what a Photo json should look like, here’s what an Album looks like, etc.

Then Unwalled Garden project does a pretty good job of defining an open shared schema

There is a github repo where the schema will be defined :

You should add the link to there as well.
