Capability Statement Structure

​

Software Information

• software.name - Server name
• software.version - Server version
• software.releaseDate - Release date

​

Implementation Details

• implementation.description - Implementation description

​

Supported Formats

• format - List of supported content types (JSON, XML, etc.)

​

REST Capabilities

• rest.mode - Server mode (server or client)
• rest.resource - List of supported resources

​

Resource Capabilities

• type - Resource type name
• interaction - Supported interactions (read, create, update, delete, search, etc.)
• searchParam - Supported search parameters
• operation - Supported operations
• versioning - Versioning support (versioned, versioned-update, no-version, versioned)
• readHistory - Whether history is supported
• updateCreate - Whether updates can create resources
• conditionalCreate - Whether conditional create is supported
• conditionalUpdate - Whether conditional update is supported
• conditionalDelete - Whether conditional delete is supported

​

Operations

• rest.operation - System-level operations
• rest.resource[].operation - Resource-specific operations

​

Use Cases

• Discover which resources are supported
• Learn which search parameters are available
• Check which operations are supported
• Determine versioning behavior
• Understand server capabilities before making requests

​

Notes

• The capability statement is always available at /fhir/metadata
• It reflects the current server configuration
• Use it to build dynamic clients that adapt to server capabilities
• The statement may change as the server is updated or configured
