NCBI BioSample

The NCBI BioSample database stores submitter-supplied descriptive information, or metadata, about the biological materials from which data stored in NCBI’s primary data archives are derived. NCBI’s archives host data from diverse types of samples from any species, so the BioSample database is similarly diverse; typical examples of a BioSample include a cell line, a primary tissue biopsy, an individual organism or an environmental isolate. The BioSample database promotes the use of structured and consistent attribute names and values that describe what the samples are as well as information about their provenance, where appropriate.NCBI BioSample数据库（NCBI BioSample Database）存储由提交者提供的描述性信息，即元数据（metadata），这些信息对应NCBI一级数据档案中所存储数据的来源生物材料。NCBI一级数据档案收录了源自任意物种的各类样本数据，因此BioSample数据库同样涵盖丰富多样的样本类型；BioSample的典型示例包括细胞系、原发性组织活检样本、单一生物体或环境分离株。BioSample数据库倡导采用结构化且统一的属性名称与属性值，以清晰描述样本本身的特征，并在适用情况下提供样本的来源溯源信息。
