The document discusses recommendations from the HIT Standards Committee's Power Team regarding metadata elements and standards for patient identity, provenance, and privacy. For patient identity, the Power Team recommends metadata elements such as name, date of birth, address, and patient identifiers, and suggests using HL7 CDA R2 format. For provenance, the recommended metadata elements are tagged data element identifier, time stamp, actor and actor's affiliation, and digital certificate. The Power Team suggests expressing these in HL7 CDA R2 format. For privacy, the document discusses use cases, a sensitive information model, rationale for suggested metadata including content metadata like data type and sensitivity, and compares standards like CDA R2
