Foreword
ISO (the International 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 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 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 International
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 document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO/IEC 23000-7:2008 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.

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 Introduction
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 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 Digital 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 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 part of the reference software.

8.2 Architecture
The following picture shows the high-level architecture of the open access application format reference
software:
GUI
Application
Data Model File Manager Model Manager
JAXB Library
I / O
DOM Library
Figure 2 — Reference software architecture
The software is structured in the four main parts: the GUI, the Data Model, the File Manager and the Model
Manager.
The GUI package 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
representation 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 Manager. 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 save 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 modification 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 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. 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 File and Model Managers. The main functions of
these Managers are described in Table 2.
