I noticed an inconsistency between HAPI server and Health Intersections FHIR server for the population of - HAPI includes the $ prefix and Health Intersections does not.

A ticket has been raised on the specification, because it isn't very clear likely resulting in this inconsistency.

I also posted a message on Zulip and got a response from Grahame Grieve (included below) that the $ is a prefix and the actual operation name does not include the $, hence it should not be included. That seems reasonable, but I've left the ticket open on the FHIR spec because the section in question isn't clear about this and could be better.

However this means that HAPI should not include the $ prefix in

Dion McMurtrie: FYI @grahame Grieve and @james Agnew, I just created on inconsistency. The question is whether the "$" should prefix the name in this attribute - HAPI includes the "$", Health Intersections test FHIR server doesn't. Which is right?

Grahame Grieve: DIon - I think that the docuemntation is specific, and that the name does not include the $

Dion McMurtrie: Not from what I can see at - it says "The name of a query, which is used in the _query parameter when the query is called." and the comments are "The name here SHOULD be the same as the name in the definition, unless there is a name clash and the name cannot be used."

Dion McMurtrie: But maybe I'm not reading something into that I should be? Or perhaps there is another part of the spec which clarifies it?

Grahame Grieve: "Most Operations are a POST to a FHIR endpoint, where the name of the operations is prefixed by a "dollar sign" ('$') character"

Dion McMurtrie: OK, that works for me. I think a slightly more specific comment at could avoid this inconsistency, even just a link to the text you just quoted. I'll raise a bug on HAPI.
