Lunar Information Element Data Dictionary
This standard specifies the framework, structure and content of the lunar information element data dictionary. GB/T33991—2017
This standard applies to the design and compilation of lunar information element data dictionary, and can be used as the basis for the description, processing, exchange, publication and application of lunar information elements.
2 Terms and Definitions
The following terms and definitions apply to this document. 2.1
Lunar Information
lunarinformation
Information about lunar resources obtained by lunar probes. 2.2
lunarinformationelement
Lunar information element
Basic unit of lunar information.
Note: A lunar information element is unique in a lunar information entity. 2.3www.bzxz.net
Lunar Information EntitylunarinformationentityA group of lunar information elements that describe the same characteristics of lunar information. Note: It can contain one or more lunar information elements. 2.4
lunarinformationsubset
Lunar information subset 1
Subset of lunar information, consisting of related lunar information entities and metadata. 2.5
Lunar information elements lunarinformationessentials Basic objects for describing lunar resource information, which are a combination of lunar information elements and lunar information entities, including basic lunar parameters, lunar environmental information, lunar rock and mineralogy information, and lunar morphology information. 2.6
datadictionaryforlunarinformationessentials Data dictionary for lunar information elements
A collection that defines and describes the composition structure and content of lunar information elements. Framework of lunar information element data dictionary
The framework of lunar information element data dictionary consists of three layers: lunar information subset, lunar information entity and lunar information element. Among them, the lunar information element is the smallest unit of lunar information. The lunar information entity is composed of lunar information elements, and other lunar information entities can be nested. The lunar information subset is composed of multiple lunar information entities and lunar information elements whose description contents have a logical relationship. The composition relationship between the lunar information subset, lunar information entity and lunar information element is shown in Figure 1. 1

4.1 Attribute structure
There are moon information
Information elements
List the attribute items contained in each moon information element in the form of a table. Each attribute item can be either an independent moon information element or a moon information entity. Each attribute item is defined by name, English name, description, constraint/condition, maximum number of occurrences, data type, and value range.
Note: The attribute items listed in the attribute table are not all, and users can expand them as needed. 4.2 Name
The name of the attribute item must be unique in the moon information element it describes. 4.3 English Name
The English representation of the attribute item name, which is unique in the lunar information element it describes. The English name of the attribute item is expressed in uppercase English full name, and multiple English words are connected by "". 4.4 Description
Explanation of the meaning of the attribute item. If the attribute has a measurement, the unit should be indicated. 4.5 Constraints/Conditions
Specify that the attribute item is a required attribute or a conditionally optional attribute of the element. When the attribute item is a required attribute of the element, it is represented by the letter "M", and when the attribute item is a conditionally optional attribute of the element, it is represented by the letter "O". 4.6 Maximum Number of Occurrences
The maximum number of instances that the attribute item can have in the lunar information query it describes. Those that appear only once are represented by 1\, those that can appear repeatedly are represented by "N", and those that appear a fixed number of times are represented by the corresponding number. 2

4.7 Data Type
GB/T33991—2017
Specifies the data type of the attribute item. The data types used in this standard include character type, numeric type, Boolean type, date type, class (a complex representing multiple data), etc.
4.8 Range
The range of the attribute item is the range of possible values ​​of the attribute item. The range of the value of the attribute item is given in the following way: if it can be listed in full by simple enumeration, list all its values, and separate multiple values ​​with ""; if the value of the attribute item is specified or explained in other materials, it is indirectly given by reference to the material (see Appendix B); if there are certain rules or conditions for the value of the attribute item, it is indirectly given by rules or conditions.
