A code specifying how concurrent Acts are resynchronized in a parallel branch construct.

Discussion: This attribute is part of the workflow control suite of attributes. An action plan is a composite Act with component Acts. In a sequential plan, each component has a sequenceNumber that specifies the ordering of the plan steps. Branches exist when multiple components have the same sequenceNumber. Branches are parallel if the splitCode specifies that more than one branch can be executed at the same time. The joinCode then specifies if and how the braches are resynchronized.

The principal re-synchronization actions are (1) the control flow waits for a branch to terminate (wait-branch), (2) the branch that is not yet terminated is aborted (kill-branch), (3) the branch is not re-synchronized at all and continues in parallel (detached branch).

A kill branch is only executed if there is at least one active wait (or exclusive wait) branch. If there is no other wait branch active, a kill branch is not started at all (rather than being aborted shortly after it is started.) Since a detached branch is unrelated to all other branches, active detached branches do not protect a kill-branch from being aborted.

Properties

This code system defines the following properties for its concepts

Name

Code

URI

Type

Description

Specializes

Coding

The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.

Generalizes

Coding

Inverse of Specializes. Only included as a derived relationship.

internalId

http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id

code

The internal identifier for the concept in the HL7 Access database repository.

Status

status

http://hl7.org/fhir/concept-properties#status

code

Designation of a concept's state. Normally is not populated unless the state is retired.

Concepts

This case-sensitive code system http://terminology.hl7.org/CodeSystem/v3-ActRelationshipJoin defines the following codes in a Is-A hierarchy:

Code	Display	Definition	internalId	Status
D	detached	Detach this branch from the other branches so it will not be resynchronized with the other branches.	10364	active
K	kill	When all other concurrent branches are terminated, interrupt and discontinue this branch.	10362	active
W	wait	Wait for this branch to terminate.	10361	active
X	exclusive wait	Wait for any one of the branches in the set of exclusive wait branches to terminate, then discontinue all the other exclusive wait branches.	10363	active
