Sahana Standards

Welcome to the Sahana standards homepage. Here we build and agree on cross-Sahana project development and interop standards which increases the bar of the quality and flexibility of the Sahana projects towards our end goals. The evolution of these standards beyond the scope of just Sahana will be to the H-FOSS group and groups such as W3C and OASIS. We strive to support Open Standards as much as possible where we can.

What makes an Open Standard?

For a standard to be truly open (at least for us) it should have the following going for it in order of priority.

  1. A liberally licensed specification - Not all standards are free and some require royalties to obtain. Licenses should be aligned to the Free and Open Source principles.
  2. An Open Community Process - Not all standards are defined and refined in an open community process. Some require exclusive memberships before you can participate
  3. An Open Source implementation - This is not a must, but it certainly helps assure that the standard has been implemented transparently. It also help propagate the standard as any one can adopt these libraries into their products.
