Planning: work through it, ballot it in September http://bit.ly/argo-auth

How is this related to CDS Hooks? It would enable presenting relevant app functionality based on the context (e.g. a diagnosis the clinician is typing is).

Just EHR -> App? That is the abstraction: app just accesses the 'EHR' being one FHIR endpoint. Under the hood multiple servers and services (FHIR and OAuth2) may be involved.

Open issues:

GF#8776 Chris gives an overview. Links to searching through a tree, and to searching through a chain. Also relates to a closure in a vocabulary search (with an 'is-a' traversal) This limits to a 'partOf' element, so a relation to itself.

It looks like comparable concepts for Url (simple) and Token (that requires terminology evaluation). More generic solutions: add expressions to say how many levels you want to descend. Chris has implemented it just for 'partOf' relations. Circularity means an error. Go further: · mention in the SearchParameter somehow if this is possible for that parameter. · try it in a connectathon

GF#5173 Is-Modifier Idea: keep it, but add a property to the concept itself stating whether it actually modifies meaning. Problem: some concepts are used in different places, with different meaning (most notably: boolean) Resolution filed.
