What do FHIR resources aim to define?

• A. The information contents and structure for the core information set that is shared by most implementations
• B. A Data Model for Clinical Workflows
• C. A Standard for Data Transport Only
• D. A Specification for Patient Consent

Answer: (A)

FHIR resources define the data payloads and how they are organized so health information can be exchanged reliably across systems. Each resource specifies what information is included (the data elements and their types) and how that information is structured (cards, relationships, and constraints), creating a common, reusable building block for interoperability. This foundation covers the core information most implementations need to share, with profiles and extensions available to adapt specifics while preserving a shared base. It’s not only about how data moves (transport) or about workflows or consent in isolation, but about defining the actual contents and structure of the data that will be exchanged.
