Overview

Different events can be used to increment a composite version number using the increment-metadata macro.

You can add a condition to a trigger to increment one element of a composite version.

In this approval workflow the approver in the Review state chooses the element of the composite version update being approved.

• the composite version number is set as a metadata value of 1.0.0 for @current-version@ on the page creation
• a workflow parameter Update type is created as a list type parameter with a choice of three values, one for each composite version element - Major, Minor, Patch
• the content review approve decision requires the setting of the Update type  workflow parameter value prior to the approved transition
• the required parameter value for the Approved transition is selected from the list options of a Major update, a Minor update or a Patch update

• the choice of Major, Minor or Patch parameter value acts as a condition for one of three triggers to update the appropriate metadata version component of @current-version@ using the increment-metadata macrotype  workflow parameter value prior to the approved transition
• the required parameter value for the Approved transition is selected from the list options of a Major update, a Minor update or a Patch update

Use of triggers

The workflow uses the following trigger actions

• a pagecreated event trigger initializes a version value using the set-metadata macro
• three pageapproved event triggers increment the component version value using the increment-metadata macro. Each trigger updates a different element of the composite metadata version number
• a statechanged event trigger clears any existing value for the @Update type@ workflow parameter on a transition to the Review state

Each of the three pageapproved event triggers listen for the approval decision for the Approved content review in the Review state. But each trigger has a condition based on the type of version update set by the approver.

• the condition is the value of the workflow parameter Update type=Major update or =Minor update or =Patching update.

Using set-metadata macros, values for the following metadata are also updated in each of these three triggers.

• @last-approver@
• @last-date@
• @current-type@

These are displayed on the content using the pageheader macro.

You may need to refresh the page content to view changes in the displayed metadata values.

Workflow parameter value trigger condition

Major, Minor and Patch are workflow parameter values set as a list option choice for the workflow parameter @Update type@.

Once confirmed the approved transition occurs.
