### FHIR RESTful Capabilities

The Da Vinci CDex Data Source Server SHALL:

1. Support at least one of the CDex approaches for exchanging clinical information:

   1. Direct Query
   2. Task-Based Approach
   3. Attachments

2. Support JSON source formats for all Da Vinci CDex interactions.

3. Follow the guidelines for Generating and Verifying Signed Resources if signatures are required.

4. Declare a CapabilityStatement identifying the scenarios, transactions, and profiles supported.

   - Follow the guidelines for Conforming to CDex Task Based Approach if supporting this exchange.
   - Follow the guidelines for Conforming to CDex Attachments if supporting this exchange. The Da Vinci CDex Data Source Server MAY:

5. Support XML source formats for all Da Vinci CDex interactions.

   > Implementers that choose to support XML need to be aware that JSON Web Signatures can only be created and validated in the original native JSON. Transforms to and from XML will invalidate signatures.

Security:

1. For general security consideration refer to the FHIR Security and Privacy Considerations.
2. For security considerations specific to this guide refer to the Security and Privacy section.
