Metadata Versioning Implementation

Examples and support material for the Metadata Versioning White Paper.

Example Metadata Update

A Metadata Update Request is carried in a ebRS SubmitObjectsRequest with a ws:Action of urn:ihe:iti:2008:UpdateDocumentSet. SubmitObjectsRequest is required since both new (SubmissionSet and Association) and updated (ExtrinsicObject) content is included. The use of new ws:Action allows implementations to handle the request differently and apply different policy and security assertions as needed. Note that the UpdateDocumentSet request is always carried in a SIMPLE SOAP package as shown below. Since this transaction only carries metadata, MTOM/XOP is not necessary.
