Xopus: The web based WYSIWYG XML editor

Write structured content in a familiar, easy to use interface

Xopus is a WYSIWYG XML Editor that runs in your browser. Xopus enables authors to work with structured and complex content without the need for technical knowledge. Xopus presents the author with a friendly interface to XML. The author cannot break the XML structure or write content that does not conform to the XML Schema.

Xopus Benefits

Control your brand identity
Xopus is a structured editor that separates content and style, which means authors can write documents limited to styles you define in advance.
Target your audience more accurately
Attract more visitors and enjoy a higher ranking in search engines. Using Xopus, you can write high quality, accessible semantic documents.
Fortify your content investment
Content written in Xopus is of a higher quality and can be used for years, even in today's ever-changing digital environment. Xopus stores documents in XML, which has widespread support in computer systems. Xopus allows you to define your own XML flavor to leverage benefits specific to your organisation. Authors can edit existing XML documents in a rich user interface provided by Xopus.
Improve your workflow efficiency 
High quality document formats such as those supported by Xopus can be published in multiple ways. For example, one document can be published online, on mobiles, in print, and as e-paper or e-books. There's no need to copy and paste documents from one application to another. Xopus can track and show the changes authors make to shorten the review cycle.
Improve your content consistency
It's easy to share your documents with other authors. That's because Xopus runs in your web browser. Since you define what documents should look like in advance, you control the quality of the content. You can write documents that conform to enterprise standards such as DITA and DocBook without having to know about those standards, which allows you to focus on writing instead.
Complement your online strategy
Xopus runs in a web browser and is design to be integrated in your content management and workflow systems. Xopus can also be used in Application Service Provider (ASP) business models.
Get your development team excited
Developers can get up to speed quickly with Xopus because it's based on popular open standards such as XML, XML Schema, XSLT, Javascript and CSS stylesheets. And it's easy to integrate Xopus into web server environments such as Java, .NET or PHP.
Reduce your author training costs 
With Xopus, you don't have to worry about training authors to use it. That's because Xopus works like most word processors (like Microsoft Word). And since Xopus limits edits to a predetermined structure, authors don't need to have any technical savvy to get started writing.
Reduce your software maintenance costs
Getting Xopus set up within your organisation is easy. There's no need to install or maintain software on your computer. All you need is one of our supported web browsers and you're set.
