How to use the `DatasetLinks` key

[Mark Mikkelsen]

Hi,

In the dataset_description.json file, one is required to use `DatasetLinks` if BIDS URI are used (which I have in my dataset). However, I'm a bit unclear what to enter in the field. I'm I supposed to link every single data file that has BIDS URI?

which BIDS URIs you have? (give examples)

have you looked at examples in https://bids-specification.readthedocs.io/en/stable/common-principles.html#bids-uri ?

Hi Mark,

The idea of DatasetLinks is that if you use, e.g.
`bids:MySourceDataset:path/to/reference/file`, then DatasetLinks
should have an entry `MySourceDataset` that points to the dataset
containing that file. If you just use `bids::` to refer to local
files, it is not needed.

Best,
Chris

Hi Chris,

So I have, as an example, this for a `mrsref`file: "AnatomicalImage": "bids::sub-02/ses-01/anat/sub-02_ses-01_T1w.nii"

Does this mean `DatasetLinks` is not needed in my dataset_description.json file?

Correct. We probably want to clarify that in the spec.

Best,
