Smart City Data Fusion
Part 2.Data Coding Specification
1 Scope
This part of GB/T 36625 specifies the coding structure and coding rules of smart city data identifiers.
This part is applicable to standardize the coding of data identifiers from different sources in the process of smart city data fusion.
2 Normative references
The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article
Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document.
GB/T 7027-2002 Basic principles and methods of information classification and coding
GB/T 26231 Information Technology Open System Interconnection Object Identifier (OID) National Numbering System and Operating Regulations
GB/T 36625.1 Smart City Data Fusion Part 1.Conceptual Model
3 Terms and definitions
The following terms and definitions defined in GB/T 36625.1 apply to this document.
3.1
Dataidentifierforsmartcity
A set of symbols or codes used to uniquely identify smart city data.
4 Abbreviations
The following abbreviations apply to this document.
OID. Object Identifier (ObjectIdentifier)
5 Identifier coding structure
5.1 The composition of the identifier code
The smart city data identifier code consists of four parts. prefix code, data source system code, data status code and data extension code
to make. Use "." to separate each part.
5.2 Representation of identifier encoding
The representation of the identifier code is shown in Figure 1.
6 Identifier coding rules
6.1 Prefix code
6.1.1 Encoding method
The prefix code is used to uniquely identify legal persons, other organizations, and natural persons that provide smart city data. Encoding method of prefix code
It is. the main body code of the main body type code of the smart city data node.
6.1.2 Smart City Data Node
Smart city data nodes are represented by OID codes, and the format is. 1.2.156.3008.1.Among them, "1.2.156" is the national OID node,
"3008" is a node in the smart city field, which is allocated by relevant state agencies in accordance with GB/T 26231, and "1" is a data node in the smart city.
6.1.3 Subject type code
The subject type refers to the classification of the subject of smart city data, and its code is represented by 1 digit. Use "0" for legal persons and other groups
Weaving; Use "1" to represent natural persons.
6.1.4 Main body code
The subject code refers to the unique identification code of the subject under a specific classification, and the country is used to uniquely identify legal persons and other organizations and natural persons.
The standard code of knowledge.
Example 1.For legal persons and other organizations registered in the People's Republic of China, my country adopts a unified social credit code identification, that is, it is identified by 18 Arabic numerals
Or capitalized English letters, represented by the registration management department code (1 digit), the organization category code (1 digit), the registration management agency administrative division code (6 digits), and the main body identification code
(Organization code) (9 digits) and check code (1 digit) are composed of 5 parts. See GB 32100-2015 for the numbering system.
Example 2.For citizens of the People's Republic of China, my country adopts the identification of the resident ID number, that is, it is composed of a 17-digit body code and a check code.
The column sequence from left to right is 6-digit address code, 8-digit date of birth code, 3-digit sequence code and 1-digit check code. See the numbering system
GB 11643-1999.
6.1.5 Coding structure
The coding structure of the prefix code is shown in Figure 2.
Example 1.The prefix code "1.2.156.3008.1.0.12100000400009880K" identifies "the unified social credit code data service center of national organizations". its
Middle. "1.2.156.3008.1" means smart city data node, "0" means legal person and other organizations, "12100000400009880K" means unified social credit code.
Example 2.The prefix code "1.2.156.3008.1.0.12100000400002195R" identifies "China Electronics Standardization Institute". Where. "1.2.156.3008.1"
Represents smart city data nodes, "0" represents legal persons and other organizations, and "12100000400002195R" is the unified social credit code.
6.2 Data source system code
The data source system code can be represented by numbers, letters or a combination thereof, and the total length should not exceed 14 digits. Code of data source system
The code rules are as follows.
a) The system that can obtain the software copyright registration number uses the software copyright registration number identification, and the software copyright registration number is composed of.
Four-digit year number SR The serial number of the year;
b) For systems that cannot obtain the software copyright registration number, a custom numbering identification can be used. The custom numbering rule is. the first time the system is uploaded
Line four-digit year number UN serial number.
6.3 Data status code
The data status code is used to identify whether data from different sources has undergone fusion processing, and "N" is used to indicate the number of data that has not been processed by multi-source fusion.
Data is the source data; "Y" represents the data that has undergone multi-source fusion processing.
6.4 Data extension code
The data extension code is allocated by the smart city data fusion unit as needed, and the allocation should follow the following basic requirements.
a) The data extension code should not be empty, and variable length characters can be used, but the structure should be as simple as possible and the length as short as possible;
b) The data extension code should be unique within the same "prefix code/data source system/data status/" code;
c) If the data extension code contains several sections, each section should express different category attributes to facilitate the realization of different dimensions
Search;
d) The data extension code should be able to reflect the main characteristics or attributes of smart city data, and be sustainable and scalable;
e) The data extension code should meet the requirements of GB/T 7027-2002, or use the existing code preparation standard.
