Back to tutorials sectionThese tutorials cover atomic types creation. They don't explicitly use any other types (it does use system types, since every custom type automatically derives from a system Sider type). Instead, they are building blocks for other types and mostly are embedded (
/type/@category is
embedded). By their nature they are very simple, with minimal interface, and focus on capturing small, but commonly used data (such as person name, URL, address, phone, etc.)
