Change Tracking is a way to keep a history of the changes made to a document. When change tracking is enabled, the inserted and deleted content is highlighted in the document allowing you to easily identify the affected regions. Tracked changes can be rendered in callouts (balloons) displayed at the side of the document, with connecting lines pointing to the changed content.
<oXygen/> has some advanced change tracking features: it keeps record of the changes made to attribute values and element breaks (splits) and also renders changes from reused content, like DITA content reference, XIncluded modules, or XML Entities.
<oXygen/> supports changes from multiple authors, rendering each author changes with different colors.
For each change <oXygen/> stores the author and the date when that change was performed. The name of the author who is currently making changes and the colors can be customized from the Track Changes preferences page. It is possible to add comments to the changes.
In the screenshot you can see how various insert/delete changes made by various authors are displayed (the option to display changes as balloons is on).
You can review the changes made by you or other authors and then accept or reject them using the Track Changes toolbar buttons or by using the change management dialog.
When you annotate your XML documents, the comments are displayed in the Author view as side callouts (balloons) showing also additional information like the author and the comment time.
The comment support is not limited to a document type (DocBook or DITA for instance). You can use it on any document that is opened in the Author editing mode. The comment data is stored in the XML document as processing instructions, so it will not interfere with your XML tool chain.
You can access the comments actions from the application toolbar:
The Review panel provides a simplified way of monitoring all the inserted content, deleted content, comments, and highlights in an XML document. This handy tool is especially useful for large teams that work on the same project and need to gather and manage all the edits. The Review panel offers a wide range of reviewing actions and a search filter.
With the Color Highlighting feature you can use the digital marker to emphasise important fragments of your documents. This is especially useful when you want to mark XML document sections that need further work or just the attention of others.
