// URN is a friendly, but unique, URN for a resource, most often auto-assigned by Pulumi. These are
// used as unique IDs for objects, and help us to perform graph diffing and resolution of resource
// objects.
//
// In theory, we could support manually assigned URIs in the future. For the time being, however,
// we have opted to simplify developers' lives by mostly automating the generation of them
// algorithmically. The one caveat where it isn't truly automatic is that a developer -- or
// resource provider -- must provide a semi-unique name part.
//
// Each resource URN is of the form:
//
2022-09-14 02:12:02 +00:00
// urn:pulumi:<Stack>::<Project>::<Qualified$Type$Name>::<Name>
//
// wherein each element is the following:
//
2022-09-14 02:12:02 +00:00
// <Stack> The stack being deployed into
// <Project> The project being evaluated
// <Qualified$Type$Name> The object type's qualified type token (including the parent type)
// <Name> The human-friendly name identifier assigned by the developer or provider
//
// In the future, we may add elements to the URN; it is more important that it is unique than it is
// human-typable.
