What We Do


RSGP designs, develops and implements state of the art software for several industry sectors, including scholarly publishing, and Engineering. RSGP believes in the philosophy of open knowledge and promotes the use of Open source software. Some of the tools we use are PHP, Python, JavaScript, TeX, MySQL, XML, XSLT and Tikz.


We put our 25 years experience in composing complicated scholarly pages into a series of cloud-based modules, resulting in a complete end-to-end publishing system. It took us 8 years but we didn’t compromise. We are proud to say that as with any good software, there are no instructions for users! And it allows publishers to save up to 80% in time and money. Our platforms allow authors, copy editors, peer reviewers and publishers to create more accurate content, using a delightful interface, faster and more cost effectively.


It may come as no surprise that we favour ePub as the single format for publishing eBooks. ePub is a comprehensive XML specification, and standardizing on this single open format will make it easier for all in future.

Our XML-first technology is ideally suited to rendering ePub on the fly, and our “filters” can generate ePub dynamically from the definitive XML file. Our strategy is to use TeX as the rendering engine. As part of this programme, we have succeeded in porting TeX to the iPhone and iPad.


We are market leaders in technical typesetting, with an emphasis on mathematical typesetting. Our speciality, almost unique in the world of typesetting, is true and automated XML first conversion of complex text to any format that the publisher desires, be it PDF, HTML, or ePub.


RSGP is part of River Valley Technologies which was set up in the UK by Dr Kaveh Bazargan in 1988. A physicist by training, his intense interest in the emerging area of desktop publishing led him to start a service company for publishers, with the aim of delivering cutting edge technology to academic publishers. 28 years later, the company has expanded internationally, and remains at the forefront of technology.

River Valley Technologies has always had a reputation for cutting edge technology. We were one of the first users of Adobe Illustrator. In 1989, we created the artwork for a book published by Blackwell Science (“Linear Algebra and Ordinary Differential Equations“). To our knowledge this was the first book published in the UK with computer generated illustrations. We pioneered the practice of scanning figures at high resolution and at print quality, directly from the desktop. This allowed full camera-ready copy to be delivered to publishers.

In 1999 River Valley Technologies came up with the revolutionary new idea of using “structured” TeX for delivering composition work to STM publishers. The system has stood the test of time to this day, and allows the efficient delivery of the most complex XML content.
