TypeSchema is a JSON format to describe data models in a language neutral format. A TypeSchema can be easily transformed into specific code for almost any programming language. This helps to reuse core data models in different environments. More information at: https://typeschema.org
TypeHub is a collaborative platform to design open data specifications, it is like GitHub but instead of code we model data.
Please take a look at our Model repository where we have TypeSchema specifications of popular schema specifications like i.e. OpenAPI etc. You can also use those specifications to generate data models in your preferred language.
