Topic: Influencing canonical URLs

From http://hl7.org/fhir/uv/shorthand/reference.html#canonical-url:
Each project MUST have an associated canonical URL, used for constructing canonical URLs for items created in the project. It is up to implementations to decide how this association is made.
With sushi is there a way for me to control the canonical URL of extensions I define in a project (e.g., so they omit the /StructureDefinition path segment)?

Hey @Josh Mandel. By default, SUSHI will create extension definition URLs using the following formula:
${canonicalBase}/StructureDefinition/${id}
If you want to override that, you must do it on a case-by-case basis by assigning the ^url in the extension definition. E.g.:
Extension: MyExtension
Title: "My Extension"
Description: "Didn't I already tell you it's my extension?"
* ^url = "http://example.org/stuffthatismine/thisextension"
* value[x] only boolean
Chris Moesel (Feb 17 2022 at 18:53):
We could provide a mechanism to globally override the basic format that is automatically applied by SUSHI, but there really hasn't been much (any?) demand for that.

That example accomplishes just what I want -- and it's straightforward enough syntax. Thank you!

NP. In FSH profiles and extensions you can always use * ^sdElementName to get directly at an element in the StructureDefinition or * elementPath ^edElementName to get directly at an element in the ElementDefinition. (Well, almost always. We don't allow you to directly muck with ^snapshot.element or ^differential.element in SDs because we really want to manage those element arrays on our own).
