Agenda

Implement the following changes per 2 new CPs

  • CP 1: Align AuditEvent and Provenance action/activity element name and definition. Recommend changing to "activity".

AuditEvent.action [Change to AuditEvent.activity

Question: What to do with the definitional differences - e.g., possibly combine. Current AuditEven.action Definition: Indicator for type of action [Change to "activity".] performed during the event that generated the audit. Control 0..1 Binding AuditEventAction: Indicator for type of action[Change to "activity".] performed during the event that generated the audit. (Required) Type code Requirements This broadly indicates what kind of action [Change to "activity".] was done on the AuditEvent.entity by the AuditEvent.agent.

Definition: An activity is something that occurs over a period of time and acts upon or with entities; it may include consuming, processing, transforming, modifying, relocating, using, or generating entities. Control 0..1 Binding ProvenanceEventCurrentState: The activity that took place. (Extensible) Type Coding

Current Audit.entity.lifecycle Definition Identifier for the data life-cycle stage for the entity. Control 0..1 Binding AuditEventObjectLifecycle: Identifier for the data life-cycle stage for the object. (Extensible) Type Coding Requirements Institutional policies for privacy and security may optionally fall under different accountability rules based on data life cycle. This provides a differentiating value for those cases. Comments This can be used to provide an audit trail for data, over time, as it passes through the system." Possible Provenance.entity.lifecycle would be the same as the Audit.entity.lifecycle.

Minutes

  • Kathleen cochaired.
  • After a quick review of the agenda, participants decided to defer discussion until John Moehrke, the Security FHIR Facilitator, is able to join.
  • Kathleen submitted CP 9407 which reads: Consider aligning AuditEvent and Provenance by changing "AuditEvent.action" to "AuditEvent.activity" per Security WG objective to align concepts/elements/definitions across FHIR AuditEvent, Provenance, and Security Labels and FHIR Consent Directive with W3C PROV to the extent that alignment makes sense. And/or provide more documentation about how the AuditEvent.action relates to the Provenance.activity associated with the same event.

Consider harmonizing or bi-referencing AuditEvent.action/activity and Provenance.activity definitions. For example: AuditEvent.action/activity Definition: Indicator for type of action [Change to "activity"?] performed during the event that generated the audit. The AuditEvent.action/activity is a system view of all or a component activity in the same event's Provenance.activity. Provenance.activity Definition: An activity is something that occurs over a period of time and acts upon or with entities; it may include consuming, processing, transforming, modifying, relocating, using, or generating entities. The Provenance.activity is a workflow view of an audited single or multiple component system event.

  • Kathleen submitted CP9417which reads:  Add a new Provenance.entity.lifecycle element to align with Audit.entity.lifecycle.  This element would track a Provenance.entity's lifecycle stage prior to the Provenance.activity by which an agent generates the Provenance Target.

That target's lifecycle stage as authenticated may be updated if it is an entity input to a succeeding legally authenticated version of the same Resource. E.g.,an authenticator signs a completed resource input, thereby creating the Provenance target,. That target may then become the authenticated entity in a Provenance Resource on a legally authenticated verson of that entity [new Provenance target] by way of a legal authenticator's signature. Provide documentation explaining the relationship of Provenance.activity to Provenance.entity.lifecycle, and its concurrent relationship to any associated AuditEvent.entity.lifecycle.

  • Call adjourned early.
