Agenda

To align with Provenance, Contract and ConsentDirective agent definition updates [Contract/CD CP 9566], revise current AuditEvent.agent definition as follows: "Several agents may be associated (i.e. has some responsibility for an activity) with an activity and vice-versa. For example, in cases of actions initiated by one user for other users, or in events that involve more than one user, hardware device, software, or system process. However, only one user may be the initiator/requestor for the event." Need documentation or modeling approach to tell which of possibly several AuditEvent.agent(s) is the initiator/requestor

Revision to above to include both an update to definition and comment Change Definition to:  "An actor taking a role in an activity  for which it can be assigned some degree of responsibility for the activity taking place. Description: An agent can be a person, an organization, software, device, or other entities that may be ascribed responsibility." To align with Provenance, Contract and ConsentDirective agent definition updates [Contract/CD CP 9566], revise current AuditEvent.agent COMMENT as follows: "Several agents may be associated (i.e. has some responsibility for an activity) with an activity and vice-versa. For example, in cases of actions initiated by one user for other users, or in events that involve more than one user, hardware device, software, or system process. However, only one user may be the initiator/requestor for the event." Need documentation or modeling approach to tell which of possibly several AuditEvent.agent(s) is the initiator/requestor.


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

Security CP 9570 - Change AuditEvent.agent definition

  • Security CP 9571 Change Provenance.agent definition
  • Kathleen did walk through of harmonization map among these Resource "agent" definitions and comments. John explained how the additional fields such as Notes, Requirements, etc. are used.
  • WG decided to wait until FM reviews CP 9566 before approving these definitions to make sure that all align before committing to Build.
  • Discussed the various approaches to ranking and typing "bags of agents" including situation where the ranking is between a delegator and a delegatee. This impacts approaches to use of a Signature Datatype "who" as a delegatee such as a Device, which cannot be a signer party, to sign on behalf of the legal party. Tabled until next call after issue is reviewed by FM on 2/19 call.
