A little bit of history. Manuals have always included images, parts diagrams, and references to other documents. Those links and metadata are a significant part of what makes a manual effective. The internet is perfect for making these documents come alive, making it possible to connect procedures with tools and reference specifications. Unfortunately, the vast majority of manuals distributed online don't take advantage of this flexibility. PDF documents are static, have no structure to their data.
A huge amount of useful data is buried, trapped in static documents where it cannot be leveraged, built upon, and repurposed.
oManual is an XML-based data standard that solves this problem. Publishing manuals as both user-friendly PDF / HTML and machine-friendly oManual files allows for the best of both worlds: manuals that retain their ease of use, but are also easy to maintain and build upon.
