The Rule Book (GE/RT8000) and other National Operations Publications are documents that contain direct instructions for railway staff. The Rule Book is held in printed copy by over 100,000 people from a number of companies across the rail industry. Even greater numbers of people are known to use it as a reference and information document both from the United Kingdom and abroad using the online PDF version. The Rule Book is a vital safety document. It comprises a set of modules and handbooks which contain direct instructions for railway staff. It sets out the operational rules for application on the GB mainline railway, which are necessary to enable the safe and timely delivery of people and goods to their destination and to provide the framework to enable safe engineering operations. We a seeking a supplier to convert our existing Rule Book documents (PDF derived from Quark) into structured DITA XML topics and maps, which supports a single source approach for writing and publishing to multiple formats. Converted content will then be migrated into our content management system (RMDB) to support the ability to update and publish information via RMDB to mobile devices such as tablets, smart phones and supported on any windows, mac and android devices with standard browsers. The vision is to create a digital product that enables the user to access current content (and beyond) in a variety of ways, providing them with the flexibility to tailor the offering to suit their personal learning styles and preferences. A space that provides access to relevant information (while online and offline), but where text is contextualised through the integration of diagrams, images, audio and video. A platform that enables information to be communicated accurately in a concise and consistent manner. RSSB will be holding a supplier engagement day at the RSSB offices on Tuesday 16 February 2016 at 1100 – 1600 with opportunity to have a 1-1 meeting (20 mins) following an RSSB presentation. Please can you confirm if you would like to attend the event by 14.00 hours Friday 12 February 2016.
