Tutorial: ArtifactsΒΆ
Biology is measured in samples that generate batches of data.
LaminDB provides a framework to transform these batches into more useful representations: validated, queryable datasets, machine learning models, and analytical insights.
The tutorial has two parts, each is a Jupyter notebook:
Tutorial: Artifacts - register & access
Tutorial: Features & labels - validate & annotate
SetupΒΆ
Install the lamindb
Python package:
pip install 'lamindb[jupyter,aws]'
Init a LaminDB instance with a directory ./lamin-tutorial
for storing data:
!lamin init --storage ./lamin-tutorial # or "s3://my-bucket" or "gs://my-bucket"
Show code cell output
π‘ connected lamindb: anonymous/lamin-tutorial
import lamindb as ln
ln.settings.verbosity = "hint"
Show code cell output
π‘ connected lamindb: anonymous/lamin-tutorial
What else can I configure during setup?
Instead of the default SQLite database, use PostgreSQL:
db=postgresql://<user>:<pwd>@<hostname>:<port>/<dbname>
Instead of a default instance name derived from storage, provide a custom name:
name=myinstance
Beyond the core schema, use bionty and other schemas:
schema=bionty,custom1,template1
For more, see Install & setup.
Track a data sourceΒΆ
The code that generates a dataset is a transform (Transform
). It could be a script, a notebook, a pipeline or a UI interaction like an upload.
Letβs track the notebook thatβs being run:
# copy-pasted identifiers for your notebook or script
ln.settings.transform.stem_uid = "NJvdsWWbJlZS" # <-- auto-generated by running ln.track()
ln.settings.transform.version = "0" # <-- auto-generated by running ln.track()
# track the execution of your notebook or script
ln.track()
Show code cell output
π‘ notebook imports: lamindb==0.72.1
π‘ saved: Transform(uid='NJvdsWWbJlZS6K79', version='0', name='Tutorial: Artifacts', key='tutorial', type='notebook', created_by_id=1, updated_at='2024-05-25 15:25:09 UTC')
π‘ saved: Run(uid='P9kYEqYnPcIMvDW9mZZE', transform_id=1, created_by_id=1)
π‘ tracked pip freeze > /home/runner/.cache/lamindb/run_env_pip_P9kYEqYnPcIMvDW9mZZE.txt
Run(uid='P9kYEqYnPcIMvDW9mZZE', started_at='2024-05-25 15:25:09 UTC', is_consecutive=True, transform_id=1, created_by_id=1)
By calling track()
, the notebook is automatically linked as the source of all data thatβs about to be saved!
What happened under the hood?
Imported package versions of current notebook were detected
Notebook metadata was detected and stored in a
Transform
recordRun metadata was detected and stored in a
Run
record
The Transform
class registers data transformations: a notebook, a pipeline or a UI operation.
The Run
class registers executions of transforms. Several runs can be linked to the same transform if executed with different context (time, user, input data, etc.).
How do I track a pipeline instead of a notebook?
transform = ln.Transform(name="My pipeline", version="1.2.0")
ln.track(transform)
Why should I care about tracking notebooks?
If you can, avoid interactive notebooks: Anything that can be a deterministic pipeline, should be a pipeline.
Just: much insight generated from biological data is driven by computational biologists interacting with it.
A notebook thatβs run a single time on specific data is not a pipeline: itβs a (versioned) document that produced insight or some other form of data representation (with parallels to an ELN in the wetlab).
Because humans are in the loop, most mistakes happen when using notebooks: track()
helps avoiding some.
(An early blog post on this is here.)
Manage artifactsΒΆ
Weβll work with a toy collection of image files and transform them into higher-level features for downstream analysis.
(For other data types: see Data types.)

Our goal is to turn these directories into a validated & queryable dataset that can be used alongside many other datasets.
Register an artifactΒΆ
LaminDB uses the Artifact
class to manage datasets & models that are stored as files, folders, or arrays. Artifact
is a registry to manage search, queries, validation & storage access.
Letβs create a Artifact
object for one of the studies:
artifact = ln.Artifact(
"s3://lamindata/iris_studies/study0_raw_images"
)
artifact
Show code cell output
π‘ path in storage 's3://lamindata' with key 'iris_studies/study0_raw_images'
Artifact(uid='1D5EmvL1nq5sTzpEY7Vy', key='iris_studies/study0_raw_images', suffix='', size=658465, hash='IVKGMfNwi8zKvnpaD_gG7w', hash_type='md5-d', n_objects=51, visibility=1, key_is_virtual=False, created_by_id=1, storage_id=2, transform_id=1, run_id=1)
Which fields are populated when creating an artifact record?
Basic fields:
uid
: universal IDkey
: storage key, a relative path of the artifact instorage
description
: an optional string descriptionstorage
: the storage location (the root, say, an S3 bucket or a local directory)suffix
: an optional file/path suffixsize
: the artifact size in byteshash
: a hash useful to check for integrity and collisions (is this artifact already stored?)hash_type
: the type of the hash (usually, an MD5 or SHA1 checksum)created_at
: time of creationupdated_at
: time of last update
Provenance-related fields:
created_by
: theUser
who created the artifacttransform
: theTransform
(pipeline, notebook, instrument, app) that was runrun
: theRun
of the transform that created the artifact
For a full reference, see Artifact
.
Upon .save()
, artifact metadata is written to the database:
artifact.save()
Show code cell output
Artifact(uid='1D5EmvL1nq5sTzpEY7Vy', key='iris_studies/study0_raw_images', suffix='', size=658465, hash='IVKGMfNwi8zKvnpaD_gG7w', hash_type='md5-d', n_objects=51, visibility=1, key_is_virtual=False, created_by_id=1, storage_id=2, transform_id=1, run_id=1, updated_at='2024-05-25 15:25:11 UTC')
What happens during save?
In the database: A artifact record is inserted into the artifact
registry. If the artifact record exists already, itβs updated.
In storage:
If the default storage is in the cloud,
.save()
triggers an upload for a local artifact.If the artifact is already in a registered storage location, only the metadata of the record is saved to the
artifact
registry.
We can get an overview of all artifacts in the database by calling df()
:
ln.Artifact.df()

View data lineageΒΆ
Visualize data lineage with view_lineage()
:
artifact.view_lineage()

Or directly access its linked Transform
& Run
records:
artifact.transform
Show code cell output
Transform(uid='NJvdsWWbJlZS6K79', version='0', name='Tutorial: Artifacts', key='tutorial', type='notebook', created_by_id=1, updated_at='2024-05-25 15:25:09 UTC')
artifact.run
Show code cell output

(For a comprehensive example with data lineage through UI uploads, pipelines & notebooks of multiple data types, see Project flow.)
Access an artifactΒΆ
path
gives you the file path, a UPath
object:
artifact.path
Show code cell output
S3Path('s3://lamindata/iris_studies/study0_raw_images')
Typically, your artifact is in cloud storage - to cache it locally, call cache()
:
artifact.cache()
Show code cell output
PosixUPath('/home/runner/.cache/lamindb/lamindata/iris_studies/study0_raw_images')
If the data is large, youβll likely want to query it via backed()
or shard the adata across many array-like artifacts. For more on this, see: Query arrays.
How do I update an artifact?
If youβd like to update metadata:
artifact.description = "My new description"
artifact.save() # save the change to the database
If youβd like to replace the underlying stored object, use replace()
.
Filter & search artifactsΒΆ
You can search artifacts directly based on the Artifact
registry:
ln.Artifact.search("iris").df().head()
Show code cell output
uid | version | description | key | suffix | accessor | size | hash | hash_type | n_objects | n_observations | visibility | key_is_virtual | storage_id | transform_id | run_id | created_by_id | updated_at | |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
id | ||||||||||||||||||
1 | 1D5EmvL1nq5sTzpEY7Vy | None | None | iris_studies/study0_raw_images | None | 658465 | IVKGMfNwi8zKvnpaD_gG7w | md5-d | 51 | None | 1 | False | 2 | 1 | 1 | 1 | 2024-05-25 15:25:11.501744+00:00 |
You can also query & search the artifact by any metadata combination.
For instance, look up a user with auto-complete from the User
registry:
users = ln.User.lookup()
users.anonymous
Show code cell output
User(uid='00000000', handle='anonymous', updated_at='2024-05-25 15:25:07 UTC')
How do I act non-anonymously?
Filter the Transform
registry for a name:
transform = ln.Transform.filter(
name__icontains="Artifacts"
).one() # get exactly one result
transform
Show code cell output
Transform(uid='NJvdsWWbJlZS6K79', version='0', name='Tutorial: Artifacts', key='tutorial', type='notebook', created_by_id=1, updated_at='2024-05-25 15:25:09 UTC')
What does a double underscore mean?
For any field, the double underscore defines a comparator, e.g.,
name__icontains="Martha"
:name
contains"Martha"
when ignoring casename__startswith="Martha"
:name
starts with"Martha
name__in=["Martha", "John"]
:name
is"John"
or"Martha"
For more info, see: Query & search registries.
Use these results to filter the Artifact
registry:
ln.Artifact.filter(
created_by=users.anonymous,
transform=transform,
suffix=".csv",
).df().head()
Show code cell output
uid | version | description | key | suffix | accessor | size | hash | hash_type | n_objects | n_observations | visibility | key_is_virtual | storage_id | transform_id | run_id | created_by_id | updated_at | |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
id |
You can also query for directories using key__startswith
(LaminDB treats directories like AWS S3, as the prefix of the storage key
):
ln.Artifact.filter(key__startswith="iris_studies/study0_raw_images/").df().head()
Show code cell output
uid | version | description | key | suffix | accessor | size | hash | hash_type | n_objects | n_observations | visibility | key_is_virtual | storage_id | transform_id | run_id | created_by_id | updated_at | |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
id |
Note
You can look up, filter & search any registry (Registry
).
You can chain filter()
statements and search()
: ln.Artifact.filter(suffix=".jpg").search("my image")
An empty filter returns the entire registry: ln.Artifact.filter()
For more info, see: Query & search registries.

Version artifactsΒΆ
If youβd like to version an artifact or transform, either provide the version
parameter when creating it or create new versions through is_new_version_of
.
For instance:
new_artifact = ln.Artifact(data, is_new_version_of=old_artifact)
Are there remaining questions about storing artifacts? If so, see: Storage FAQ.
CollectionsΒΆ
Often times, several artifacts together represent a collection.
Letβs seed a growing Collection
of artifacts:
collection = ln.Collection(
artifact,
name="Iris collection",
version="1",
description="Iris study 0",
)
collection.save()
Now, we collect more data in subsequent studies.
We want to keep track of their data as part of a growing versioned collection:
artifacts = [artifact]
for folder_name in ["study1_raw_images", "study2_raw_images"]:
# create an artifact for the folder
new_artifact = ln.Artifact(f"s3://lamindata/iris_studies/{folder_name}").save()
artifacts.append(new_artifact)
# create a new version of the collection
collection = ln.Collection(
artifacts, is_new_version_of=collection, description=f"Now includes {folder_name}"
)
collection.save()
Show code cell output
π‘ path in storage 's3://lamindata' with key 'iris_studies/study1_raw_images'

Most functionality that you just learned about artifacts - e.g., queries & provenance - also applies to Collection
.
Collections become powerful if you directly leverage them for training models: Train a machine learning model on a collection.
