14、l 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 by
15、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 of
16、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 Inter
17、national 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 documen
18、t may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

20、09(E) ISO/IEC 2009 All rights reserved 1 Information technology Multimedia application format (MPEG-A) Part 7: Open acces application format AMENDMENT 1: Conformance and reference software for open access application format After Clause 6, add the following two new clauses: 7 Conformance 7.1 Introdu
21、ction This clause defines the conformance of implementations to the open access application format specified in the previous clauses. 7.2 File conformance Conformant files shall be readable by the open access application format compliant implementations including the reference software as described
22、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 conformance A player application for content consumption is conformant to this standard, if the application can correctly read the file format, parse the Di
23、gital Item Declaration in the xml-box and display this information. 7.4 Creator application conformance A file creator application is conformant, 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
24、 for creating and consuming conformant open access application format compliant files. The Java programming language is used for the implementation 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
25、 part of the reference software.

26、:2009(E) 2 ISO/IEC 2009 All rights reserved 8.2 Architecture The following picture shows the high-level architecture of the open access application format reference software: The software is structured in the four main parts: the GUI, the Data Model, the File Manager and the Model Manager. The GUI p
27、ackage contains the user interface for the interaction with the user. The inputs from the user are processed as events that call the respective functions in the Managers to process the Data Model. The Data Model can be divided into the Content Model and the User Data Model. The Content Model is a re
28、presentation of the data contained in the file format, which contains information about the resources and the metadata. The User Data model stores the information about the user of the application and also contains application preferences. The Managers are divided in the File Manager and the Model M
29、anager. The File Manager can be used to create, parse and save open access application format compliant files. These Open Access files are based on the MPEG-21 file format and shall be conformant to the specification in 6.8. Additionally the File Manager also provides functions to add, delete and sa
30、ve contents that are packaged within an Open Access file. The Model Manager is specialized to process xml data and is used for the generation and parsing of XML using the JAXB and the DOM library. The Model Manager provides methods for the extraction of specific data from the model and the modificat
31、ion of the model. 8.3 Functional description The reference software has two modes of operation: The content creation and the content consumption. The modes of operation are controlled in the GUI, which uses the functions of the Model Manager to process the data model for the creation and consumption
32、 of items. The functions of the File Manager are applied for the file creation and parsing and also for the resource handling. 8.3.1 Content creation For the content creation the user can create a package file and add content files as items into the package. These content files can be arbitrary data
33、. When the user finishes the packaging, an Open Access file can be generated, that can be released and consumed afterwards. The user can specify the metadata for the item within the application. The information in the user interface is saved into the data model with the functions provided by the Fil
34、e and Model Managers. The main functions of these Managers are described in Table 2.

Furthermore the u
44、ser can extract the content out of the file, which includes the transmission of Event Reports. The main functions of the reference software for content consumption are described in Table 3.
