These notes contain the current thinking on how to map Document Sharing attributes to FHIR. This page will be updated as we learn more.

In the tables below, the left side is the current ebRIM content and the right side is the proposed FHIR content.

DocumentEntry

DocumentEntry Wrapper

<ExtrinsicObject

<DocumentReference>
   <text>
      <status value="generated"/>
      <div  xmlns="http://www.w3.org/1999/xhtml">
      </div>
   </text>
 </DocumentReference>

The text element represents an HTML rendition of the DocumentReference. This example shows that the HTML has been generated.

  </author>

The contained elements go after the text element and before the masterIdentifier. These are formed as contained elements because this content would normally already be in a FHIR repository and simply referenced by this DocumentReference resource. Note that these items are referenced by the id attribute on the Practitioner elements.

mimeType

    mimeType="text/plain"

   <mimeType value="text/plain"/>

uniqueId

<ExternalIdentifier
  identificationScheme="urn:uuid:2e82c1f6-a085-4c72-9da3-8640a32e42ab"
  value="1.3.6.1.4.1.21367.2005.3.7"
  objectType="urn:oasis:names:tc:ebxml-regrep:ObjectType:RegistryObject:ExternalIdentifier"
  id="id_10" registryObject="Document01">
  <Name>
    <LocalizedString value="XDSDocumentEntry.uniqueId"/>
  </Name>
</ExternalIdentifier>

  <masterIdentifier>
    <system value="urn:ietf:rfc:3986"/>
    <value value="urn:oid:1.3.6.1.4.1.21367.2005.3.7"/>
  </masterIdentifier>

The uniqueId is represented by the masterIdentifier. The big different is that in XDS the value is an OID and in FHIR it is a fully qualified OID.
