Common definitions for public service delivery. Built so programs can coordinate, share data, and reach the people they serve.

PublicSchema gives governments, development organizations, and technology partners a shared language for describing people, programs, enrollments, payments, and the other building blocks of service delivery.

• Concepts like Person, Household, Enrollment, and PaymentEvent, each with a plain-language definition, properties, and data classification guidance.
• Properties that are independent and reusable across concepts, with clear semantics and sensitivity labels.
• Vocabularies (controlled value sets) that reference international standards (ISO, FHIR, UN) where they exist, and define new sets only where no standard covers the domain.

• Descriptive, not prescriptive. Everything is optional. Systems adopt what they need.
• Plain language. Definitions are written for policy officers, not developers.
• Standards-aligned. Built on JSON-LD with stable URIs, designed for use as Verifiable Credential schemas.
• Evidence-based. Informed by convergence analysis across real-world social protection systems.
