The Sample object may be a surrogate for taxonomy accession or an anonymized individual identifier. Or, it may fully specify provenance and isolation method of the starting material. Short text that can be used to call out sample records in search results or in displays. NCBI Taxonomy Identifier. This is appropriate for individual organisms and some environmental samples.

Links to resources related to this sample or sample set (publication, datasets, online databases). Properties and attributes of a sample. These can be entered as free-form tag-value pairs. For certain studies, submitters may be asked to follow a community established ontology when describing the work. SAMPLE_SET serves as a container for a set of samples and a name space for establishing referential integrity between them.
