Which FHIR resource represents the data of a single raw artifact as digital content accessible in its native format?

• A. DocumentReference
• B. CatalogEntry
• C. Binary
• D. Linkage

Answer: (C)

Storing a single raw artifact in its native digital format is what the Binary resource is designed for. It acts as a dedicated container for binary content, holding one binary artifact per resource. The key pieces are the contentType, which records the MIME type of the data, and the data field, which contains the base64-encoded binary payload. This makes it possible to transfer and store raw files (like PDFs, images, or other binary formats) in a consistent, standard way within FHIR. DocumentReference describes and locates a document and may point to binary data via an attachment or a URL, but it does not store the binary content itself. CatalogEntry is about cataloging products, not raw data artifacts. Linkage is about declaring relationships between resources, not storing artifact content. Therefore, the Binary resource is the appropriate place to represent the data of a single raw artifact in its native format.
