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.
If you’re wanting to try out DITA Compare’s powerful performance, try our online demo which offers fundamental functionality; Diff two of your own DITA files and compare the changes. If you’d like to see all DITA Compare has to offer book a one-to-one demo with a DeltaXML developer.
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
i and semantic inline markup such as
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.
When you publish documents, like standards, that are relied on as a key part of your customers’ work it can be difficult for them to manage the transition to an updated version. Many customers, including standards bodies (international, national and industry-specific), use DeltaXML’s products to drive a redline document workflow. DITA Compare identifies the changes between publication versions, marks them in the source XML and the resulting output feeds into the usual publication workflow where styling is added to changed content to help your customers to understand exactly what updates appear in this latest revision.
Reviewing document updates can be an onerous task, particularly when the documents are large. The task becomes much easier if you can see exactly what has changed since the last time the document was reviewed. DITA Compare identifies changes between two specific revisions, allowing you to produce a version specifically for reviewers that highlights the precise changes that you want them to review. Because it operates on the source XML there is no need for change tracking and you have the flexibility to edit and review on different platforms. If your reviewer is familiar with XML editors, DITA Compare can even generate PIs to show the changes it identified as if they were track changes in a range of popular tools.
Finding changes between your DITA files is just the beginning. When you’re working with multiple extensive files, the ability to accept found change and merge them into a single DITA document is a powerful application that saves you time. Try our DeltaDITA package which gives you the ability to find DITA diffs and then merge DITA files into a single repository.
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.
