Not just a DITA diff tool. DITA Compare is an enterprise solution for finding and processing changes between two DITA documents. Output differences to a number of pre-defined outputs, including our HTML side-by-side view or output to a DITA file and process diffs within your editors however you wish, wherever you need.
DITA Compare’s algorithms allow you to compare two DITA documents, analysing their content and structure and matching up all the corresponding elements between them to accurately identify and represent changes in your documents.
DITA Compare’s configurability allows you to focus on differences important to you, and represent them in DITA markup. This representation combines your original content with the new markup making it possible to see the individual changes in your content.
Accessed through Java or REST APIs integrate into any enterprise workflow or content management system.
There’s no need to change your existing DITA publication workflows for DITA Compare. The comparison process is tailored specifically for DITA content producing valid DITA output, where changes are marked using native DITA markup. Elements are marked with the @status and @rev attributes and text changes are wrapped in elements (or pre-DITA 1.3) to enable the change markup to be applied at the word level.
DITA Compare handles structural markup like b and i and semantic inline markup such as cite and term with specific processing so that the focus is on content change without any adverse effects from formatting. The list of elements to handle is fully configurable, allowing you to add or remove elements from our predefined list or replace the whole list with your own.
MathML handling is built into DITA Compare as standard. When MathML content inside your documents is compared, change highlighting is created using MathML syntax adding colouring and styling to your MathML. Three different output styles allow you to choose the one that best suits your publication.
Comparison results can be configured to show in any form you need, whether for automated processing or human review.
DITA tables are complex enough without having to worry about how to compare them. We process CALS and HTML tables to make sure that the results are valid against the table models while still delivering accurate comparisons.
When editing documents it’s commonplace to move chunks of content from one location to another. In these circumstances, it can be useful to understand that this was a move operation rather than a deletion and an addition. DITA Compare uses element ids to identify this type of change and mark it as a move so that you have the option to style it differently if needed.
Understanding when externally referenced content changes is just as important as understanding text changes within a document. DITA Compare can identify when a referenced image has changed but can also identify when a modified href actually points to the same image.
What is DITA Compare?
DITA Compare is a complete toolkit for reliable DITA comparison. It is the most efficient and dependable way of comparing and finding all of the changes within your DITA content.
How do I integrate or embed DITA Compare?
DITA Compare is optimised for integration into enterprise workflow and content management systems. All of its functionality is accessed through its Java or REST APIs, which are fully documented and come with complete, working examples. On top of these API’s we have created plugins for popular XML authoring tools, including oXygen and FrameMaker for seamless content authoring and reviewing.
Can I ignore changes I know about?
Yes. DITA Compare can be configured to tell you about the differences that matter to you and ignore those that don’t, including changes to attributes, the order of content, differences in whitespace and external links.
How is DITA Compare different from other diff tools?
DITA Compare works at the map or topic level, bringing comparison functionality for reusable components or complete documents.
Rather than comparing line-by-line, it identifies and matches up all the elements across your DITA content within the document context. This pairing process uses a combination of element names, parent names, position in the XML tree and the structure of child elements to provide you with an easily understandable and accurate comparison result.
How are found differences represented?
DITA Compare generates well-formed, valid DITA content so the resulting output is compatible with your existing DITA tools. It has been designed to make all your content changes easy to work with. Where this involves tables, a sophisticated process works out the best way of showing all the changes, while still generating a valid table.
