TableInfo: file.tsv

The file.tsv table will contain one row for each file in your program.

Field	Field Description	Required?	Field Value Type	Extra Info
id_namespace	A CFDE-cleared identifier representing the top-level data space containing this file [part 1 of 2-component composite primary key]	Required	string	id_namespace is a unique URI prefix pre-registered with CFDE and attached to your program (or a subset of your program) that identifies anything labeled with it as belonging to you. Please see the technical documentation for a full discussion of how this information is built and used.
local_id	An identifier representing this file, unique within this id_namespace [part 2 of 2-component composite primary key]	Required	string	The string formed by concatenating the id_namespace and local_id field values must be unique for each row in this table. Please see the technical documentation for a full discussion of how this information is to be used.
project_id_namespace	The id_namespace of the primary project within which this file was created [part 1 of 2-component composite foreign key]	Required	string	This will be the value of id_namespace in the row in project.tsv corresponding to the primary project that generated this file. If your program has not registered multiple CFDE identifier namespaces, this will be exactly the same value for all rows.
project_local_id	The local_id of the primary project within which this file was created [part 2 of 2-component composite foreign key]	Required	string	This will be the value of local_id in the row in project.tsv corresponding to the primary project that generated this file.
persistent_id	A persistent, resolvable (not necessarily retrievable) URI or compact ID permanently attached to this file	Optional	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 through which the file can be accessed. 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. Please see the technical documentation for a full discussion of how this information is to be used.
creation_time	An ISO 8601 -; RFC 3339 (subset)-compliant timestamp documenting this file's creation time	Optional	(string) YYYY-MM-DDTHH:MM:SS±NN:NN	Examples: 2021-01-08 ("Jan 8, 2021") 2021-00-00T00:00:00-00:00 ("2021") 2021-01-08T00:45:40-04:00 ("Jan 8, 2021, 12:45:40AM, Zulu minus 4") Please see the technical documentation for a complete treatment.
size_in_bytes	The size of this file in bytes	Non-required: Any number of rows after the header can be filled	Value type is integer	do not include decimal places or decimal sign (.)
uncompressed_size_in_bytes	The total decompressed size in bytes of the contents of this file	Non-required: Any number of rows after the header can be filled	Value type is integer	do not include decimal places or decimal sign (.)
sha256	(preferred) SHA-256 checksum for this file [sha256, md5 cannot both be null]	Either this field OR md5 must be populated	Value should be HSA-256 hash or nothing; If you have both please use sha256	You may populate both md5 and sha256 for a given row, but only one is required
md5	(allowed) MD5 checksum for this file [sha256, md5 cannot both be null]	Either this field OR sha256 must be populated	Value should be MD5 hash or nothing; If you have both, please use sha256.	You may populate both md5 and sha256 for a given row but only one is required
filename	A filename with no prepended PATH information.	Non-required: Any number of rows after the header can be filled	Value type is string	Filenames do not need to be unique. Uniqueness is ensured by the local_id
file_format	An EDAM CV term ID identifying the digital format of this file (e.g. TSV or FASTQ)	Non-required: Any number of rows after the header can be filled	Value must be a valid EDAM ID	EDAM format lookup Example valid EDAM IDs: format:1930 format:3712 format:2310
data_type	An EDAM CV term ID identifying the type of information stored in this file (e.g. RNA sequence reads)	Non-required: Any number of rows after the header can be filled	Value must be a valid EDAM ID	EDAM data type lookup Example valid EDAM IDs: data:2044 data:2050 data:2082
assay_type	An OBI CV term ID describing the type of experiment that generated the results summarized by this file	Non-required: Any number of rows after the header can be filled	Value must be a valid OBI ID	OBI lookup service Example valid OBI IDs: OBI:0000366 OBI:0001177 OBI:0002763
mime_type	A MIME type describing this file	Non-required: Any number of rows after the header can be filled	Value must be a valid MIME type	Common MIME types Tutorial for bulk MIME type identification Example valid MIME types: image/jpeg text/html application/octet-stream
