12、ional Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established
13、 by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field
14、 of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft I
15、nternational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this doc

It is designed for the cases where users own rights to a piece of content and have an interest in releasing it in such a way that other users can freely access it. However, the users do not want to make the con

This type of release is called “open access” and the set of technologies that support it is called open access application format. Examples of open access contents are publicity material and tease

Another important application is in the scientific area, where publications, research results or e-learning material are published. Open access is an application format (AF) and is specified as
