As a key element of technological innovation, scientific data is experiencing a rapid increase in the scale and frequency of its sharing and exchange, creating a greater need for efficient and timely scientific data exchange. The need is becoming increasingly urgent. Scientific data harvesting, as a method of scientific data interoperability between systems, is initiated by the party acquiring the scientific data. Scientific data or information from another scientific data platform can be obtained through an application programming interface (API). Harvesting operations can be automated and multi-functional. Frequent, on-demand processing reduces manual workload while improving data exchange efficiency. Scientific data management institutions can act as data collection... The party that harvests data can also be the party whose data is being harvested, thereby achieving the goal of on-demand exchange of scientific data between scientific data management institutions. It can effectively improve the standardization and efficiency of scientific data aggregation and exchange among scientific data management institutions. Scientific Data Harvesting Standards

1 Scope

GB/T 46411-2025 is the Chinese national standard covering harvesting metadata from one repository into another - the protocol and the request and response formats, the incremental harvesting since the last run, the handling of deleted records, and the identifiers that keep a harvested record tied to its source. First edition, already in force. Issued on 5 October 2025, it has been in force since 5 October 2025.

This document specifies the content, process, and requirements for the harvesting of scientific data. This document applies to scientific data management institutions conducting scientific data harvesting, biological germplasm and experimental material resource banks, and other physical scientific and technological resources. The platform is used for scientific data harvesting and reference.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 scientific data In the fields of natural sciences and engineering technology, scientific research activities produce results, as well as those obtained through observation, monitoring, investigation, and testing. Records of original and derived information obtained through methods such as [list of methods], or other data that can be used for scientific research activities. [Source: GB/T 43708-2025, 3.1]

3.2 A set of characters used to uniquely identify scientific data.

3.3 metadata Data that defines and describes other data. [Source: GB/T 18391.1-2009, 3.2.16]

3.4 data entity A set of data content that has a specific theme, can be uniquely identified, and can be processed by a computer.

Note. It generally consists of one or more forms such as data files and databases. [Source: GB/T 39912-2021, 3.7, with modifications]

3.5 Initiated by the party acquiring scientific data, the system proactively obtains scientific data from the other party through interoperability of application programming interfaces between platform systems.
