Metadata Search in Python TileDB SOMA Package

1

I have a question regarding the Python TileDB SOMA package. Is there a method or function available to search metadata?
For instance, let’s say I have registered a SOMA Experiment with the metadata {“analyst”: “Johnny Bravo”}. I’m looking for a method such as: ‘search_in_soma_experiments_metadata(query=“analyst == ‘Johnny Bravo’”)’.

tiledbsoma.Experiment objects are abstractions of tiledb.Groups, so you can use tiledb-py to open up the experiment as a group object and look at its metadata:

import tiledb

with tiledb.Group(soma_uri) as grp:
    print(grp.meta)

In tiledbsoma you follow a similar pattern:

with tiledbsoma.open(soma_uri) as soma_exp:
    print(soma_exp.metadata)

For users of our cloud platform, you can query all asset metadata ultra-fast using our python REST api:

import tiledb.cloud

response = tiledb.cloud.client.list_groups(
    namespace, 
    group_type="soma", 
    per_page=500,
    search="T cell",
    with_metadata=True,
)
