DirectTrust FormatCode Code System

The system of codes to express formatCode metadata defined by implementation guides published by DirectTrust. A formatCode specifies the technical format that a Direct message’s content conforms to. A formatCode is a further specialization more detailed than the mime-type. A formatCode provides sufficient information to allow any potential Content Consumer to know if it can process and/or display some or all of the content of the Direct message based on the content encoding, structure and conformance indicated by the formatCode. The set of formatCodes used across the healthcare ecosystem is intended to be extensible to easily expand interoperability.

urn:dt-org:dsm:map:cda:maternal-health-birth-notification:1.0	MAP Maternal Health Birth Notification CDA — Version 1.0	Identifies the MAP Maternal Health Birth Notification CDA content profile used as the primary document in TX3. The mother is the document recordTarget and the newborn is the subject of the newborn-information section. This is a provisional project assignment while the document, section and entry templates are established; the format code alone does not assert conformance to a finalized template.
