Document vs encounter to implement health information exchange

what is the best way to exchange data (implement health information exchange)
I choose to do it using the document way, but I saw other organizations implement data exchange using encounter resources, is it right to do to use encounter?

@lloyd can you help, please?

This section of HRex provides a nice decision tree highlighting the many mechanisms FHIR offers for data sharing and how best to choose between them. There are certainly places where document-based exchange is appropriate, but it’s rarely my first choice.

can you attach the link to the section you mentioned, please @lloyd

Bizarre. It renders like it knows it’s a link, but doesn’t let you navigate it. The URL is: http://build.fhir.org/ig/HL7/davinci-ehrx/exchanging.html
