Databoard is a software library built upon a simple but well formulated and expressive type system. The design is a compromise of expression power, advanced functions, and performance. In contrast to XML's rich and uninhibited type system, databoard's simple and controlled model has enabled more practical features. Besides the norm features ''binary serialization'', ''human readable type and value notation'', ''network communication'', there are also more advanced features such ''class binding'', ''annotations'', ''recursion'', ''type conversion'', ''value conversions'', ''value comparisons'', ''variant types'' and ''random access''.
