Joint Declaration 25 February 2008 in Geneva (Standards and the Future of the Internet)
Standards can only been declared Open if they are
1. subject to full public assessment and use without contraints in a manner equally available to all parties
2. without any components or extentions that have dependencies on formats or protocols that do not meet the definition of an Open Standard themselves;
3. free from legal or technical clauses that limit its utilisation by any party or in any business model;
4. managed and further developed independently of any vendor in a process open to the equal participation of competitors and third parties;
5. available in multiple complete implementations by competing vendors, or as a complete implementation equally available to all parties.
The Digistan definition of a free and open standard is based on the EU's EIF v1 definition of "open standard" with the language cleaned-up and made more explicit. Our analysis of the importance of vendor capture in determining the openness of a standard comes from this analysis.
