# p.data

## Syntax

**p.data**

 

## Purpose

The p.data annotation is used to tag an element as being a property of a topic. This tag is highly customizable and can be altered to be as specific as the topic requires. Content tagged as data is contained within a prolog. Applying this annotation will tag content as a generic data element.

 

A more specialized form of the <data> element should be applied if possible.

## Examples

The following is an example of a time when you might want to use the annotation:
