Existing Wording: The use of FHIR operations as the protocol for defining artifact evaluation requests and responses. In particular, the ability to bundle multiple requests into a single operation, as well as the use of a generic FHIR operation for any service module evaluation, versus defining an evaluation specific to a given knowledge artifact.

Comment:

I think the rule of thumb should be that we should perhaps have at most dozens or hundreds of operations to cover 90-95% of CDS use cases, vs. thousands or tens of thousands. This would imply that the re-use of operational structures should happen to at least some extent. Also, the ability to minimize processing time, such as through bundling, is critically important and must be a priority for the specification to support. In any case, we should make sure the proposed way forward is feasible for scalable, high-performance use.
