This category of information refers to the data or information related to a specific occurrence of a taxon (usually a species), whether in nature, in a collection or in a data set.Darwin Core is a set of standards developed and promoted by the international organization TDWG (Biodiversity Information Standards) and used by the network of the Global Biodiversity Information Infrastructure (GBIF) to facilitate the exchange of information on biological diversity.Darwin Core Archive (DwCA) is a compressed file (Zip), composed of several information files:Flat text file with the information, separated by a separator character (coma, dot and coma or tabulator). It is a file in XML format, which complies with the GMP standard (GBIF Metadata Profile), based on the EML standard (Ecological Metadata Language).Descriptor file (meta.xml), which describes the organization of the previous files. It is a file in XML format that indicates how the information of the previous files is organized, as well as the composition of the compressed file.In addition to Darwin Core format, the information is offered in excel and csv.

此类信息指与某一分类单元（通常为物种）的特定发生记录相关的数据或信息，无论该记录源自自然环境、馆藏标本还是数据集。达尔文核心标准（Darwin Core）是由国际组织TDWG（生物多样性信息标准，Biodiversity Information Standards）制定并推广的一套标准，被全球生物多样性信息基础设施（GBIF，Global Biodiversity Information Facility）的网络体系采用，以促进生物多样性信息的交换。达尔文核心归档文件（Darwin Core Archive，DwCA）为Zip格式压缩文件，由多个信息文件组成：包含以分隔符（逗号、分号或制表符）分隔信息的纯文本文件；以及符合基于生态元数据语言（EML，Ecological Metadata Language）标准制定的GBIF元数据概览（GMP，GBIF Metadata Profile）规范的可扩展标记语言（XML）格式文件。描述符文件（meta.xml）用于阐释前述文件的组织结构，该文件为可扩展标记语言（XML）格式，可说明前述文件的信息组织方式以及该压缩归档文件的构成。除达尔文核心格式外，相关信息还可通过Excel和CSV格式获取。
