Use the {increment-metadata} macro to increment major.minor.patch metadata value for a single approval using three triggers.

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 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 macrothe increment-metadata macro

Info
The example only works when the workflow is applied as a space workflow on creation of a page. The space workflow must be active to listen for the `pagecreated` event to initialize the metadata value. The `pagecreated` event trigger will not fire if the workflow is applied to existing content and the metadata value will not be initialized.

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.

In this example, the workflow must be applied in space mode on creation of a page.

Here's how each trigger action works

Trigger Event	Action macro	Notes
`pagecreated`	{set-metadata}	sets the metadata `current-version` and initializes the value to 1.0.0 on the creation of the page metadata displayed on the page using `{pageheader}` macro only occurs if the workflow is applied in space mode	o
`pageapproved\|`... ... `@Update type@=Major`	{increment-metadata} {set-metadata}	increments the composite `current-version` metadata major value by 1 each time the content is approved, the approver sets the required parameter value to Major update and transitions to Approved minor and patch value are reset to zero three separate `set-metadata` action macros update values for each of the following metadata `@last-approver@` `@last-date@` `@current-type@`	o o
`pageapproved\|`... ... `@Update type@=Minor`	{increment-metadata} {set-metadata}	increments the composite `current-version` metadata minor value by 1 each time the content is approved, the approver sets the required parameter value to Minor update and transitions to Approved patch value is reset to zero three separate `set-metadata` action macros update values for each of the following metadata `@last-approver@` `@last-date@` `@current-type@`	o o
`pageapproved\|`... ... `@Update type@=Patch`	{increment-metadata} {set-metadata}	increments the composite `current-version` metadata patch value by 1 each time the content is approved, the approver sets the required parameter value to Patching update and transitions to Approved three separate `set-metadata` action macros update values for each of the following metadata `@last-approver@` `@last-date@` `@current-type@`	o o
`statechanged\|`... ... `state=Review`	{set-metadata}	clears the value of the workflow parameter Update type on transition to the Review state the `{set-metadata` `:Update type}{set-metadata}` action macro with an empty body clears any value for the Update type workflow parameter. This means that before each Approved transition can occur the user will be required to set the Update type parameter value for that approved version.
