Key Concepts

These three concepts appear throughout the Platform and are worth understanding before reading any other section. They are not service-specific — they apply to every document, every read request, and every client application built on top of the Platform.

In this section

• Core Schema — The fixed set of base fields every Platform document carries. These fields are injected and enforced by the Platform automatically.
• Access Control — How read visibility is determined entirely by document attributes. Covers zone filtering (?zone=own,share,group,client), automatic ownership injection at write time, and the three-guard chain (AuthGuard → ScopeGuard → PolicyGuard) every request passes through.
• Coworkers Space — How multiple client applications are grouped so they can share data through the Platform without calling each other directly. Covers client registration, JWT claims, document-level sharing and CQRS webhook delivery.
