through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

Introduction

With the application of information technology to traditional Chinese medicine, the collections of data

produced in TCM clinical practice, scientific research, administrative management and other activities

involved in TCM are increasingly rich. The data come from various organizations including hospitals,

institutions, universities, enterprises and governments, etc. The data range from ancient times to the

present. Classification should be established to give better management of these data sets, including

the processing, integration, indexing and storage of data resources. Classification of traditional Chinese

medicine data sets is a prerequisite and is vitally important in data retrieval, sharing and exchange.

Making use of this classification and coding rules, traditional Chinese medicine data sets with the

same features can be classified together, while those without any similarity can be kept separate. Thus,

the data sets of traditional Chinese medicine can be managed effectively and accessed according to

various retrieval approaches, which is beneficial for highly efficient query services. The order of all the

classifications and codes in this standard only label their position in the classification system, and is

not related to the importance.

exhaustive set of mutually exclusive categories to aggregate data at a pre-prescribed level of

hierarchical classification

classification of objects using hierarchical taxonomy. Hierarchical classification systems are developed

classes that are subdivided from the most general subject to the most specific

3.5
faceted classification

system that allows the assignment of multiple classifications to an object, enabling the classifications to

be ordered in multiple ways, rather than in a single, pre-determined, taxonomic order

Note 1 to entry: Faceted classification may actually employ hierarchy in one or more of its facets. Faceted

classification systems allow the assignment of multiple classifications to an object, and enable those

classifications to be applied by searchers in multiple ways, rather than in a single, predetermined order.

properties or characteristics of a class or specific subject”.

4 Classification scheme and coding scheme
4.1 Classifying and coding Principle
4.1.1 Scientificity

TCM data sets include the collection of various data recorded in TCM activities such as clinical practice,

scientific experiments, literature resources digitalization and statistic data report, etc. The most

stable and essential properties or characteristics of TCM data sets should be identified as the basis of

classification.
4.1.2 Systematicness

The attributes or characteristics of TCM data sets are systematically arranged according to internal

relations to ensure reasonable categories, clear hierarchy and reduced redundancy. Classification

should put the partial problems into the system as a whole from the point of view of system engineering

to achieve system optimization.
4.1.3 Scalability

The categories are set up to ensure that the established classification system will not be disturbed

when a new code element and code value was added. The classification codes allow sufficient space

for expansion for the subordinate information management system which is built based on this

classification system.
4.1.4 Practicability

The classification and codes should satisfy the requirement of simple, clear and ease of use, and conform

to the common sense of the users.
4.2 Classification scheme

Hierarchical classification and faceted classification were combined together in this standard in order

to fully reveal the feature of TCM data sets. A TCM data set can be classified into different kinds of

types by data creator type, data source type and subject type, and each kind of type which is a ‘facet’

can be combined together to a new complex classification by the sequence of data creator type, data

source type and subject type. For data source type and subject type themselves, they use hierarchical

classification respectively.
4.3 Coding scheme
The classification code structure consists of four parts:
— Traditional Chinese medicine (TCM) label,
— creator type code,
— data source type code,
— subject type code.

Period “.” is used as separator between each part (Figure 1). Code value is Arabic numerals with fixed

digits which is half-width character except for TCM label.

5 Classification and code list
5.1 TCM label

In order to identify data sets of traditional Chinese medicine, three characters, namely 'TCM', are used

to represent all the data sets generated by the activities in the business domain of traditional Chinese

medicine.
5.2 Creator type

The creator type relates to the type of an entity primarily responsible for making the content of the

data set. According to the business domain of the traditional Chinese medicine, 10 types are specified

with two-digit codes, including universities and educational agency, academic Institutions, hospital

and medical centre, commercial company and manufacturer, government, international organization,

professional association/society, publishers, individual and others (Table 1).

01 Universities and Educational agency
02 Academic Institutions
03 Hospital and Medical centre
04 Commercial company and Manufacturer
05 Government
06 International organization
07 Professional Association/Society
08 Publishers
09 Individual
99 Others
5.3 Data source type

Data source type represents the type of the original source which the data were derived from. Data

source type can be divided into two category hierarchies (top level categories, sub-categories if desired).

The top level categories are specified in this document, but the sub-categories are not specified so that
