Topic: Composition with image and a contained Binary
Rik Smithies (Feb 02 2021 at 19:23):
Composition can have an image that uses data from a Binary.
<td>
<img src="#imageResource" alt="an image"/>
</td>
Does this have to be a contained resource, and not just another resource in the Bundle? The latter is not mentioned as a possibility and I can't see how it would work.
http://build.fhir.org/narrative.html#id
However a contained resource has to be referenced from the containing, but servers don't seem to be able to detect the image to resource link, and reject it because of constraint dom-3.

@Ward Weistra the firely server cannot recognise that a contained Binary resource is referenced by its container, either by noticing the "src" link (as above), or by this trick of using a dummy extension
<contained>
<Binary>
<id value="imageResource"/>
<contentType value="image/png"/>
<data value="iVBORw0-snip-="/>
</Binary>
</contained>
<!-- If there is a contained resource that is not referenced by its container, servers may reject this.
Servers may not recognise that it is referenced by id, from the text.
This extension ensures there is a reference to the contained Binary that servers can see -->
<extension url="http://example/fhir/extension/dummyValidationReference">
<valueReference>
<reference value="#imageResource"/>
</valueReference>
</extension>

@Rik Smithies Thanks for the pointer, let me ask a real Firely Server expert!

Hi @Rik Smithies : Could you send me the full resource and the http request you're issuing?
Plus the version of Firely Server you're using (or is it the public one, hence currently version 4.0.0)?
Rik Smithies (Feb 03 2021 at 15:52):
sent, thanks
