The increment-metadata macro increments a numeric metadata value. 

...

Where to use it?

One or more increment-metadata macros can be put in a trigger macro.

The metadata value must have been already set e.g. at page creation using the set-metadata macro.

Parameters

Parameter	Required	Default	Notes
metadata name		none	The metadata item. The metadata item value is numeric and can be:  simple (e.g. whole number) composite (eg 2.1 or 2.1.1) A non-numerical character can be used to separate "-" the metadata numeric values e.g. 1__2-4. The separator can be any non-numeric character. A suffix may be used after the last numeric element e.g. 2.1.1-BETA. This can be any set of characters (including letters, symbols, and numbers).
increment		increment last numeric element by 1	The increment expression, if specified, is a numeric expression to increment element(s) of the numeric value. If no increment value is specified the last numeric element of the current metadata value is incremented by 1. The expression can be: a simple integer number (e.g. 2) composite number (e.g. 1.2  or 1.2.3) A composite number cannot be more than 3 numeric elements e.g. 1.2.3.4 is not supported. When defining the increment expression the format MUST match the metadata item value format including any separators and suffix identifiers. increment or a change for non-numeric elements is not supported. incrementing a single higher-order element of a composite numeric value will reset any lower-order elements to zero e.g. a metadata value of 1.2.3 with an increment expression of 1.0.0 will update the value to 2.0.0.

Increment expression examples

...

The increment expression format including any separator characters and the suffix identifier MUST match the metadata item value being incremented. 

An <empty> increment expression simply includes the name of the metadata value to increment.

The This example shown uses the increment-metadata macro to support the custom versioning of a page using a simple numeric metadata value.

...

A version change will occur : on a state change to the Approved state.

{increment-metadata:my-version}

 The metadata is associated with the page. At any one point in time, the metadata value will be the same in any workflow state.

• for in our example, the my-version metadata value for a user viewing previously published content in the content currently in a draft state (if that content has been previously published), is the value set by the increment-metadata action on the last transition to the workflow final state whilst content in the draft state, Approved. It will be the same metadata value seen for the content by a view-only user when viewing the final state content

The Confluence version metadata value may however be different if the page has been updated or edited in one of the workflow states.

In the simple increment example, this can be seen if you use one one get-metadata macro to display the metadata my-version and a second  get-metadata macro to display the Confluence version on a page.

...

The Confluence version value is currently 9. This reflects that there have been multiple edits on the content but only one version has been approved in the workflow.

Other examples

 The metadata value set and updated using these macros is linked to the page not a page version. Viewing a previous page version will show the current metadata value.
