where to add binary resources?

[joofio]

how do we link them to the main resources besides the composition?

if nowhere, where do we add those resources in the composition? thoughts on this?
tagging @jkiddo and @cander2 at least.
Feel free to tag someone else.

I suggest to have a binary as part of the bundle - not composition. Then have a document reference referenced from the composition and have the document reference referencing the binary

[cander2]

That's what I originally wanted but apparently we need to incorporate them into the Composition.
https://chat.fhir.org/#narrow/stream/179252-IG-creation/topic/Getting.20base64.20images.20to.20display.20in.20IG

In summary, the FHIR document specification requires us to put them in the Composition in a element and then you have the with the reference value.

    <contained>
      <Binary>
        <id value="imageResource" />
        <!-- example format -->
        <contentType value="image/png" />
        <!-- data is base 64 encoded, actual bytes of the image png file -->
        <data value="Base64 Content here" />
      </Binary>
    </contained>
    <!-- this extension is necessary per image -->
    <!-- Image 1-->
    <extension url=http://ema.europa.eu/fhir/extension/dummyValidationReference>
      <valueReference>
        <reference value="#imageResource" />
      </valueReference>
    </extension>

Then add the following wherever you want the image to appear:

<img src="#imageResource" alt="an image" />

I would prefer to have the Binary as a separate resource in the Bundle and then the Composition cross-references to it. Doesn't look like that is allowed though.

Can add this to the list of things to update in the coming IG update
