Drafting.

This document is Part 3 of GB/T 18391 "Metadata Registry System for Information Technology (MDR)", which has been published.

The following section.

---Part 2: Classification;

---Part 3: Metamodel of Public Facilities in the Registration System;

---Part 4: Formation of Data Definitions;

---Part 5: Naming and Identification Principles;

This document replaces GB/T 18391.3-2009 "Information Technology Metadata Registry System (MDR) Part 3: Registry System Metadata".

Compared with GB/T 18391.3-2009, the main technical changes in "Type and Basic Attributes" are as follows, except for structural adjustments and editorial changes.

---Added a metadata registry system modeling method (see Chapter 5).

---The content of Chapter 4 of GB/T 18391.3-2009 has been modified and supplemented, and then split into.

- Basic core packages (see Chapter 6);

- Identification package (see Chapter 7);

- Referencing and defining packages (see Chapter 8);

- Registration package (see Chapter 9);

- Categorized packages (see Chapter 10);

- Item mapping package (see Chapter 11).

This document is equivalent to ISO/IEC 11179-3:2023 "Information technology – Metadata registry system (MDR) – Part 3: Registry system".

Introduction

Data processing and electronic data interchange rely heavily on the accuracy, reliability, controllability, and...

Verifiability. A consensus between data providers and users regarding the meaning and representation of the data is a prerequisite for its correct and appropriate use and interpretation.

To foster this consensus, it is necessary to define several characteristics or attributes of the data. These characteristics of data are collectively referred to as "metadata," or...

"Data that describes data".

The attributes and related metadata of data elements can be standardized and recorded as registration items in a metadata registry (MDR). Metadata the registration system is used to store information about data elements and their associated concepts, including concepts such as "data element concept," "conceptual domain," and "value domain" (see...).

ISO/IEC 11179-31). Generally, the above are all referred to as "metadata items". This metadata is essential for clearly describing, recording, analyzing, and distributing...

Classes and data management are essential.

GB/T 18391 addresses the semantics of data processing, data representation, and the registration of these data descriptions. Through these descriptions, semantics can be obtained.

A precise understanding and a useful description of the data.

The purpose of GB/T 18391 is to promote.

---Standard description of data;

---A consistent understanding of data within and between organizations;

---Reuse and standardization of data across time, space, and application;

---Collaboration and standardization of data within and between organizations;

---Management of data description components;

---Reuse of data description components.

Each part of GB/T 18391 is designed to address one aspect of the aforementioned requirements.

GB/T 18391 is proposed to consist of twelve parts.

---Part 1: Framework. This section presents the overall framework of this series of standards, including data elements, value ranges, data element concepts, conceptual domains, and concepts and generalizations.

It introduces fundamental concepts such as the concept system, providing context that connects the various parts.

---Part 2: Classification. This section elaborates on the meaning and significance of classification, and explains how to apply a classification scheme to other aspects of the registration system.

Classification standards.

---Part 3: Metamodel of the Registration System's Public Facilities. The Metadata Registry (MDR) is defined using the Unified Modeling Language (UML).

The core metamodel.

---Part 30: Basic Metadata Attributes. Describes the basic attributes of data elements and related metadata in order to avoid issues that may arise from a lack of complete metadata.

Used according to the registration system.

---Part 31: Data Specification Registration Metamodel. Provides extensions to the Metadata Registry (MDR) system for registering descriptive data elements.

Metadata for related concepts.

---Part 32: Conceptual System Registration Metamodel. Provides extensions to the Metadata Registry (MDR) system for registering descriptive conceptual entities.

Metadata of the system.

---Part 33: Dataset Registration Metamodel. Provides extensions to the Metadata Registry (MDR) system for registering descriptive datasets, Metadata of a dataset.

---Part 34: Computable Data Registry Metamodel. Provides extensions to the Metadata Registry (MDR) system for registering computable data descriptions.

Metadata of the calculation data.

---Part 35: Model Registration Metamodel. Provides extensions to the Metadata Registry (MDR) system for registering descriptive models and related metadata.

Metadata of the metamodel.

---Part 4: Forming Data Definitions. Provides guidance on how to develop clear data definitions.

---Part 5: Naming and Identification Principles. These guidelines provide direction on how to assign names to managed items.

---Part 6: Registration. Provides information on assigning a unique identifier to each data component and how registration applicants can register with the registration authority.

(RA) Operation Guide for Registering Data Components.

This document defines the information recorded in the metadata registry system in the form of a conceptual data model. This document also specifies the methods used for processing...

This document outlines the common infrastructure for the identification, naming, definition, and registration of items in various registration systems. Therefore, it also applies to systems outside of metadata registries.

Registration system. Other parts of GB/T 18391 extend this model to support specific types of metadata items, such as. data elements, data types, etc.

According to meta-concepts, data specifications, concept systems, etc. (see 1.2).

Note. For situations where a complete metadata registry system is not applicable, ISO/IEC 11179-30 describes the basic attributes of registry system items.

This document is intended for information developers, information managers, data administrators, standards developers, application developers, and business modelers.

Personnel and others responsible for making data easy to understand and share. GB/T 18391 has broad applicability across interdisciplinary fields and information technology.

Use sex.

GB/T 18391 applies to the following activities.

a) Definition, specification, and registration of metadata registration system content, including the exchange or...

Quotation;

b) Exchange or referencing between various metadata collections, including models;

c) Registration and management of semantic components useful for data management and data analysis;

d) Conceptual frameworks and relational databases, XML databases, knowledge bases, text, and graphs that may originate from natural language text understanding systems.

The relationships between data stored in a graphical database;

e) Providing services for semantic computing. semantic service-oriented architecture, semantic mesh, semantic-based workflow, semantic web, etc.

f) Support for addressing semantic web considerations such as AAA (Anyone Can Say Anything), non-unique names, and openness.

The World Hypothesis.

In Chapters 5 through 11, as well as Appendices B and C, this document uses.

--- Bold text highlights terms that represent metadata objects specified in the metamodel;

---The terms representing the concepts defined in Chapter 3 are displayed in plain font.

Example. Concept (6.4.2.2) is a class, and each instance of it builds a model of the concept.
