4 Metadata composition
iiiKAa~cJouaKAa
According to the aggregation level of meteorological archives, archive metadata is divided into three levels: category metadata, case metadata, and file metadata. Their associated characteristics are as follows:
a) Category metadata: data that describes the basic conditions such as attributes, characteristics, and status of archives of the same type. Its attributes and characteristics can be inherited by the case metadata of archives of this type:
b) Case metadata: data that describes each volume of meteorological archives. Data on basic conditions such as attributes, characteristics, and status, consisting of one or more files in the same volume at the same time, or in the same region, or in the same formation unit, or in the same project, or related in content, whose attributes and characteristics can be inherited by the file metadata in the volume of the case file; c) File metadata: data describing the attributes, characteristics, and status of each file, and the file is the smallest unit of the archive. 5.1 Category metadata consists of 11 elements: archive code, archive name, category name, category definition, classification number, category abbreviation, category alias, start year, end year, number of files, and storage capacity. 5.2 See Appendix A for the attributes of category metadata. In Appendix A, there are three types of constraints: \M” \C” and “O”. Among them, \M\ is a mandatory option, and the element cannot be empty; "C" is a conditional option, and it cannot be empty when the element meets certain conditions; "O" is an optional option, and it can be empty when the element has no content. 6 Case file metadata description method
6.1 Case file metadata consists of 3C elements: archive code, archive number, name, standard name, classification number, region number, formation unit, start date, end date, file number, file file number, keywords, filing unit, filing date, filing method, number of pieces, number of pages, storage capacity, confidentiality level, confidentiality agency, storage period, in-library status, storage location, box number, content description, change status, information status, archiving medium, update cycle, and usage rights.
6.2 Case file metadata attributes are shown in Appendix B. The constraint types in Appendix B are given according to the provisions of 5.2. 7 File metadata description method
7.1 File metadata consists of archive code, archive number, classification number, sequence number, file name, formation unit, region The domain number, formation time, file number, document number, document type, main recipient, copy recipient, confidentiality level, confidentiality agency, retention period, file type, creation method, keywords, file summary, file page number, file size, change status, storage medium, information status, library status, storage location, box number, and usage rights are composed of 29 elements.
7.2 See Appendix C for file metadata attributes. The constraint types in Appendix C are given in accordance with the provisions of 5.2. 8 Metadata file format
8.1 File type and naming
8.1.1 Metadata is stored in the form of ".XML" files. 8.1.2 The metadata file name consists of 7 parts: meteorological industry characteristics, archive industry characteristics, metadata type identifier and archive code, the earliest year of the archive collection, the year when the metadata file was formed, and the file type. 8.1.3 Archive metadata file name format: "QXDA_ZLBHY,YYY-Y, Y, Y. Y.XML", its meaning is as follows: 2
iiiKAa~cJouaKAa=
-1st to 2nd digit: fixed character QX", meteorological industry characteristic identifier;-4th to 5th digit: fixed character \DA", archive industry characteristic identifier QX/T514-2019
-7th to 8th digit: "ZL" is the archive metadata type identifier. Among them, when the metadata type is category metadata, the category identifier is "LB"; when the metadata type is file metadata, the category identifier is "AJ", and when the metadata type is file metadata, the category identifier is "WJ";
10th to 11th digit: "BM\ is the meteorological archive code (see Appendix D): 13th to 16th digit: the earliest year of the archive collection; 18th to 21st digit: the year when the metadata file was formed:-23rd to 25th digit: fixed character "XML", file type identifier. 8.2 File structure
8.2.1 The archive metadata file consists of comment lines and text. The first line of the file is a comment line, which is used to explain the XML version number and file encoding method; the text consists of a Metafile root node and multiple element sub-nodes, which are used to describe metadata attribute characteristics. 8.2.2 The Metafile root node attribute Type is the archive metadata type identifier and is a required item. When the category identifier is LB\, it is a category metadata file; when the category identifier is "AJ\, it is a case metadata file; when the category identifier is WJ\, it is a file metadata file. 8.2.3: Each element sub-node contains all elements of various metadata, corresponding to the metadata of each volume of archives (each type of archives, each file). 8.2.4 The number, element name, definition, length, data type, constraint conditions and other attributes of each element are given according to the provisions of Appendix A, Appendix B and Appendix C respectively according to the metadata type. 8.2.5 Elements with mandatory constraints cannot be omitted in the element sub-node; elements with optional constraints can be omitted in the element sub-node; elements with conditional constraints cannot be omitted in the element sub-node when the conditions are met. Example:
\QX_DA_LB_BH_YIY1Y1Y1-Y2Y2Y2Y2.XML\MetafileType=\LB\>

A set of digital numbers uniformly allocated by meteorological archives across the country. The numbers of national and provincial meteorological archives are shown in Appendix D.
Full name of the current meteorological archives in Chinese: such as China Meteorological Administration Meteorological Archives, Hebei Provincial Meteorological Archives, etc.
According to the definition of each type of archives and the observation specifications, relevant technical regulations and documents of different periods, the category names of each type of archives specifications are given, and the definition rules of each type of archives are given according to the connotation and extension of each type of archives. According to the provisions of QX/T223-2013, a set of character codes for each type of archives are given. Different media archives are distinguished by archive expansion and re-marking according to the provisions of Chapter 7 of QX/T223-2013: Among them: the first digit is the first-level classification code, the second to the third digits are the second-level classification code, the fourth to the fifth digits are the third-level classification, and the sixth to the tenth digits are the re-marking digits. Record archives can be classified and coded according to three levels; party affairs, comprehensive management, business management, scientific research management, infrastructure archives, instruments and equipment, specifications and standard measurement 7 types of archives can be classified and coded according to two levels. When the archive storage medium is a large-capacity storage medium such as a magnetic tape or hard disk, the archive classification number can cover its content by reducing the classification level. The brief description of each type of archive: For example, other names that are different from the standard category name of this type of archive, such as gas meter-1, gas meter-2, etc.: When the cover name is inconsistent with the standard alias, the archive cover name can be used as the category alias to maintain the connection with the name of the archive cover (cover), such as: the cover name of a certain type of archive is "rainfall self-recording paper". The name on the archive cover is "precipitation self-recording paper", and "precipitation recording paper" can be recorded as the category alias. The earliest year of each type of archive in the collection is based on the Gregorian calendar. The latest year of each type of archive in the collection is based on the Gregorian calendar. The total number of files of each type of paper meteorological archive: counted in volumes. Paper files are required.
Storage capacity of each type of electronic archives: Statistical unit: \M". Electronic archives are mandatory. Data
