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: 2021-01-08T00:00:00-00:00 ("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 | Optional | integer | |
| uncompressed_size_in_bytes | The total decompressed size in bytes of the contents of this file | Optional | integer | |
| sha256 | (preferred) SHA-256 checksum for this file | At least one of sha256 or md5 must be populated | SHA-256 hash string | |
| md5 | (deprecated but allowed) MD5 checksum for this file | At least one of sha256 or md5 must be populated | MD5 hash string | |
| filename | A filename with no prepended PATH information. | Optional | string | filename values do not need to be unique: record uniqueness is ensured by local_id. |
| file_format | An EDAM CV term ID identifying the digital format of this file (e.g. TSV or FASTQ) | Optional | A valid EDAM format: term | EDAM format: term lookup Example: format:1930 |
| compression_format | An EDAM CV term ID identifying the compression format of this file (e.g. gzip or bzip2): null if this file is not compressed | Optional | A valid EDAM CV term | EDAM format: term lookup Example: format:3615 |
| data_type | An EDAM CV term ID identifying the type of information stored in this file (e.g. RNA sequence reads) | Optional | A valid EDAM data: term | EDAM data: term lookup Example: data:2044 |
| assay_type | An OBI CV term ID describing the type of experiment that generated the results summarized by this file | Optional | A valid OBI term | OBI lookup service Example: OBI:0002763 |
| analysis_type | An OBI CV term ID describing the type of analytic operation that generated this file | Optional | A valid OBI term | OBI lookup service Example: OBI:0002763 |
| mime_type | A MIME type describing this file | Optional | string | Common MIME types --- Tutorial for bulk MIME type identification --- Examples: image/jpeg text/html application/octet-stream |
| bundle_collection_id_namespace | If this file is a bundle encoding more than one sub-file, this field gives the id_namespace of a collection listing the bundle's sub-file contents. Null otherwise. | Optional | 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. |
| bundle_collection_local_id | If this file is a bundle encoding more than one sub-file, this field gives the local_id of a collection listing the bundle's sub-file contents. Null otherwise. | Required for row if bundle_collection_id_namespace is filled for row | The value in the local_id column for the collection that describes the sub-files in this compressed file | |
| dbgap_study_id | The name of a dbGaP study ID governing access control for this file, compatible for comparison to RAS user-level access control metadata | Optional | String | Example: phs000710 |
