Definitions for "Open Standard"
An open standard is a specification whose description is freely available, e.g., HTML, XML. This means that developers are free to create applications which are valid according to the specification and which will therefore work with software designed for it. It is recommended best practice to use open standards and open source software, since documentation so created has the best chance of being intelligible to future generations.
Refers to a published standard that is made freely available to any person or business.
a specification to enable interoperability or portability developed through a consensus process
a detailed, descriptive overview of a process, protocol or format
