Export glossary

Complete list of definitions for the fields included in exports.

Labelbox exports give you more flexibility and control to retrieve the most valuable information from your projects. You can now select and export a subselection of the data rows of most interest based on your predefined or new parameters in the Data Rows tab. You can also export more detailed information from these data rows, and include or exclude relevant attributes in your export. We also simplified and standardized the annotation formats.

For more details on how to create exports, along with complete samples, please view the following pages:

Below is a glossary of the fields that can appear in an export.

Export fields

Labelbox exports aligns with the data-row-centric paradigm, thus every line, regardless of the export time, will include information on each included data row.

FieldIncludedDescription
data_rowAlwaysA dictionary containing the fields explained the data_row table below.
media_attributesOptionalSee Media attributes
attachmentsOptionalSee Attachments
metadata_fieldsOptionalSee Metadata
embeddingsOptionalA list of dictionaries containing precomputed and custom embeddings

data_row

FieldIncludedDescription
idAlwaysThe ID of the data row.
global_keyIf utilizedThe global key of the data row.
external_idIf utilizedThe external ID of the data row.
row_dataAlwaysThe URL to your cloud-hosted file
detailsOptionalA dictionary containing the fields explained in the details table below. When exporting through the SDK, these fields are included by setting the data_row_details parameter to True.

FieldIncludedDescription
dataset_idAlwaysThe ID of the dataset to which the data row belongs.
created_atAlwaysA timestamp that indicates when the data row was created.
updated_atAlwaysA timestamp indicating when the data row was most recently updated.
last_activity_atAlways*A timestamp indicating the last time any activity was performed on the data row.
created_byAlwaysThe email address of the user that created the data row.

* The last_activity_at field is not included in exports from a model run.

projects

The projects field contains a dictionary in which the keys are project IDs and the values consist of the fields explained below.

In a project-based export, there will only be a singular project ID in this dictionary. Yet, when exporting from the Catalog, consider that a data row may have been labeled in multiple projects, and thus the dictionary will have multiple keys.

Project IDs are used in favor of project names in order to enforce uniqueness.

idAlwaysThe ID of the label.
label_detailsOptionalA dictionary containing the fields explained in the label_details table below.
performance_detailsOptionalA dictionary containing the fields explained in the performance_details table below.
annotationsAlwaysSee the annotation export formats broken down by asset type, beginning here with images.

benchmark_scoreSituationalThe agreement score between the label and the associated benchmark label. After label submission or updates, there could be a 30-minute delay before this field gets updated.
consensus_scoreSituationalThe agreement score between the label and the associated consensus labels made on the same data row. After label submission or updates, there could be a 30-minute delay before this field gets updated.

experiments

The experiments field contains a dictionary in which the keys are model experiment IDs, and the values consist of the name and a dictionary of model runs.

runs

The model runs field contains a dictionary in which the keys are model run IDs, and the values consist of the fields explained below.

Model run IDs are used in favor of model run names to enforce uniqueness.

FieldIncludedDescription
nameAlwaysThe name of the model run.
