In their new stategy for Global Relevance (See also the article on noooxml.org) the International Standard Organization ISO have declared a new aim: the elimination of duplicate standards.
According to Haakon Meland Eriksen, the ISO member states have adopted a policy to ensure only one global ISO standard in any field. This has been done due to prior bad experiences with the several ISO standards in a single field, which lead to increased costs on the implementors because usually, devices need to support all standards and must in some cases even be able to convert products of one standard to the other, depending on the field of science the standard applied to.
According to ANSI, this policy «provides International Solutions to Market Needs».
The question that remains to be asked is whether, and if so, how this will affect the standardization process of ISO/IEC DIS 29500.
