3.1
Encapsulation
The professional digital content data is combined in one package, and the implementation form of the data is hidden from the target user.
3.2
Professional content
According to the classification of subjects and the division of social occupations, content resources for specialized research or teaching are required.
3.3

3.6
Reflowing document
Streaming document
According to the logical order of the content, the content presents a file that can adapt to changes in the screen or window of the terminal device.
[CY/T 96-2013, 6.1.6]
4 Packaging Purpose
Encapsulation is an important principle that object-oriented methods should follow. It is to combine data and behavior in a package,
The user hides the implementation form of the data.
Professional content digital reading products integrate a variety of information such as content, content organization schemes, feature plug-ins, authorization and usage policies.
The product can achieve the same use effect on different systems, different programs and hardware. The above information needs to be complete, standardized and reliable.
Integrated together to form a relatively independent product package.
5 Packaging principles
5.1 completeness
The product package should contain at least the basic information for product use, such as. package list, authorization information, usage policy, product information, and product information.
5.2 Adaptability
The packaged product should be suitable for different operating systems, hardware platforms and applications. Encapsulated files can be compatible
High, widely used format. For content that is not compatible with multiple systems at the same time, try to provide multiple versions.
5.3 Moderation
Product packaging should try to select related content and function plug-ins around a theme to avoid missing or excessive selection of content and functions
Plug-ins affect the quality of the product.
5.4 Independence
The packaged product should be independently available for use by applications, without relying on other content or feature plug-ins outside the product.
5.5 Reliability
Product packaging should use reliable technical means and algorithms to ensure that the product will not be damaged and invalidated during storage, transmission and use.
