10、ssion) 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 by the respective organization to deal with particular fields of technical activity. ISO
11、 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 of information technology, ISO and IEC have established a joint technical committee, ISO
12、/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 International Standards adopted by the joint technical committee are circulated to nationa
13、l bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

18、formance Conformant files shall be readable by the open access application format compliant implementations including the reference software as described in Clause 8. The general file-level structure of the files shall conform to the normative file structure defined in 6.8. 7.3 Player application co
19、nformance A player application for content consumption is conformant to this standard, if the application can correctly read the file format, parse the Digital Item Declaration in the xml-box and display this information. 7.4 Creator application conformance A file creator application is conformant,
20、if the application can produce files conformant to the specification in Clause 6. 8 Reference Software 8.1 Introduction The reference software can be used for creating and consuming conformant open access application format compliant files. The Java programming language is used for the implementatio
21、n of this software. The application can be used to package arbitrary files as contents into a standard conformant file. The creation of these files is not part of the reference software.
