Introduction

Since its release and implementation, GB/T 20092-2013 has been used in the application systems of many news media units. In recent years, the standard during the implementation process, some new application scenarios are constantly emerging, resulting in some new application requirements, and some application systems of the news media are gradually no longer available.

There are more and more applications to transfer manuscripts using XML format and JSON format. Because of the technical content defined by GB/T 20092-2013 it is mainly defined based on the XML format, which has gradually failed to meet the application requirements of the news media, so the main purpose of this revision is to avoid limit the standard content to a certain technology, separate the conceptual model of Chinese news information content from news metadata, and integrate news information the XML format and JSON format of the information content are standardized and defined separately, so that the scope of the standard is clearer and the definition is clearer.

GB/T 20092 aims to define the standards that are generally applicable to the collection, editing, generation, distribution, exchange, storage, retrieval, and evaluation of Chinese news information content.

In order to meet the actual needs of the latest technology in the news media, the standard to be more usable, the name of the standard is changed to "Chinese News Information Content", which is proposed to consist of four parts.

--- Part 1: Conceptual Model. The purpose is to establish an abstract conceptual model of Chinese news information in the news industry, and standardize Chinese news information. The overall structure and description of information documents provide guidance for users of news content.

--- Part 2: News metadata. The purpose is to standardize all kinds of metadata describing the content of Chinese news information, so as to facilitate the in the industry information system, the unified expression and consistent description of information content are realized.

--- Part 3: XML format for data exchange. The purpose is to specify the XML-based Chinese news information data exchange format, provide technical support for the construction of news media information system.

--- Part 4: JSON format for data exchange. The purpose is to specify the JSON-based Chinese news information data exchange format, provide technical support for the construction of news media information system.
