Where to store external links and IDs?

When registering data in LaminDB, you might want to store a reference link or ID to indicate the source of the collection.

We have reference and reference_type fields for this purpose, they are available for Collection, Transform, Run and ULabel.

# !pip install lamindb
!lamin init --storage testreference

→ initialized lamindb: testuser1/testreference

import lamindb as ln

→ connected lamindb: testuser1/testreference

Let’s say we have a few donor samples that came form Vendor X, in order to chase back the orders, I’d like to keep track the donor ids provided by the vendor:

ln.ULabel(
    name="donor 001", reference="VX984545", reference_type="Donor ID from Vendor X"
)

ULabel(uid='vy0un1Au', name='donor 001', is_type=False, reference='VX984545', reference_type='Donor ID from Vendor X', space_id=1, created_by_id=1, created_at=<django.db.models.expressions.DatabaseDefault object at 0x7fce63b1f2b0>)

!lamin delete --force testreference

• deleting instance testuser1/testreference
