Currently there is no way include a digital signature in the document header along with the identity of an author, authenticator, or legal authenticator. This information is often mandatory for legally binding documents.
High: The workaround "Signature" section (see Dicussion) is inefficient and duplicative of metadata specified in the HL7 RIM (Participation.signatureText). CBCC WG Wiki
- Add "signatureText" attribute to Participation occurrences in the document header.
Needed for Consent Directive representations. The current workaround is to specify a "Signature" section in structure body of a document because we cannot use the Participation.signatureText for legalAuthenticator, authenticator, etc. specified in the header. The following workaround would be eliminated in CDA R3 if this proposal were approved:
<section classCode="DOCSECT" moodCode="EVN">
<title>Signatures</title> <text> This section contains the signatures of the relevant authenticators</text> <entry typeCode="COMP"> <observationMedia classCode="OBS" moodCode="EVN"> <value mediaType="application/pdf" representation="B64"> ... </value> </observationMedia> </entry> </section>
This method, however, does not specify how to which authenticator is belongs, the narrative block has to specify using references.
The item was introduced during the SDWG meeting - Nov. 17th, 2009.
