TableInfo: biosample.tsv

The biosample table will contain one row per biosample in your Program

Field	Field Description	Required?	Attributes	Extra Info
id_namespace	A CFDE-cleared identifier representing the top-level data space containing this biosample [part 1 of 2-component composite primary key]	Required	Value type is string	If you have not implemented multiple namespaces every row will have the same value
local_id	An identifier representing this biosample, unique within this id_namespace [part 2 of 2-component composite primary key]	Required	The value in each row must be different for a given namespace Value type is string
project_id_namespace	The id_namespace of the primary project within which this biosample was created [part 1 of 2-component composite foreign key]	Required	Value type is string	If you have not implemented multiple namespaces, this will be the same as id_namespace.
project_local_id	The local_id of the primary project within which this biosample was created [part 2 of 2-component composite foreign key]	Required	Value type is string	For each row (each biosample), this will be the value of 'local_id' in the project table for the project this biosample came from
persistent_id	A persistent, resolvable (not necessarily retrievable) URI or compact ID permanently attached to this biosample	Non-required: Any number of rows after the header can be filled	The value in each row must be different Value type is string	Meant to serve as a permanent address to which landing pages (which summarize metadata associated with this file) and other relevant annotations and functions can optionally be attached, including information enabling resolution to a network location from which the file can be downloaded. Actual network locations must not be embedded directly within this identifier: one level of indirection is required in order to protect persistent_id values from changes in network location over time as files are moved around.
creation_time	An ISO 8601 -- RFC 3339 (subset)-compliant timestamp documenting this biosample's creation time: YYYY-MM-DDTHH:MM:SS±NN:NN	Non-required: Any number of rows after the header can be filled	Value must be datetime	Example valid dates: 2021-01-08 2021-01-08T00:45:40Z 2021-01-08T00:45:40+00:00
anatomy	An UBERON CV term ID used to locate the origin of this biosample within the physiology of its source or host organism	Non-required: Any number of rows after the header can be filled	Value must be a valid UBERON ID	UBERON lookup service Example valid UBERON IDs: UBERON:0001988 UBERON:0001052 UBERON:0006956
