schema.org
Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet, on web pages, in email messages, and beyond.
The focus is to parse JSON-LD.
It took many hours to create this library in its published form.
If you like the library and saved you much time, then maybe respect this with a small donation to the animal shelter of Stuttgart.
