We suggest that we make more specific guidelines for how to handle resource integrity and lifecycle management. We suggest that we give clear guidelines for at minimum read and other resource level interactions on merged content, and search behavior when resource identifiers are used as parameters. For the former case, we suggest performing content redirection where possible, or if not possible, to provide specific OperationOutcomes to indicate content modification caused the HTTP error. For the latter, we request guidance on specific search outcomes when resource identifiers used in the search parameters have been merged, deleted, or otherwise modified, and suggest additional OperationOutcomes specifying these particular conditions
