Inspect, download, and validate
Prove release integrity in the downstream consumer.
Prove release integrity in the downstream consumer.
Unitlab processing success confirms the release was created; downstream validation confirms the release is useful. Both are required for acceptance.
Know the expected item count, schema, geometry conventions, group behavior, splits, and source path model.
Use the same parser or consumer that production will use.
Define acceptance tolerances and the owner of a failed validation.

Inspect release metadata and sample content before download, then reproduce the same checks in the actual downstream environment.
Data Space contains My Releases and Public Releases, toggled from the page header. A release detail contains Overview, Data, and—on private workspace releases—Settings.
Opening a release item uses a separate read-only annotation viewer for Image, Video, Audio, Text, Medical, or Document. It reuses the familiar modality surface but disables mutation. This lets teams inspect exactly what a release contains without accidentally changing the project history that produced it.
Making a release public requires license selection. Release deletion is permission- and subscription-gated. If the latest release version is deleted, the previous version becomes latest.
Working converters include:

Audio
Audio JSON, RTTM, UUEF
Native single-family formats apply to one compatible family. A release containing more than one family must use UUEF or Standard Bundle.
UUEF is the universal full-fidelity format. It preserves properties, attributes, relations, item properties, tags, page/frame context, and the richer annotation graph.
Standard Bundle creates one ZIP containing a native output per selected family plus a manifest describing the release, source scope, selected types, split ratios, written files, and omitted empty combinations.
Default Standard Bundle choices are COCO for image/video/medical, JSONL for text, and Audio JSON for audio. Document data uses UUEF.
The SDK can:
create a release from a project;
specify export_type="UUEF";
define split ratios such as 80% train and 20% test;
list and retrieve releases;
download annotations for a selected split;
download associated files to a destination folder.
The SDK supports UUEF creation and split-aware annotation and file downloads. The complete release format matrix is shown above.
Mismatch
Stop consumption, isolate the scope, and determine whether the cause is source, project state, format mapping, processing, or parser behavior.
Correction
Create a new controlled release rather than altering a delivered artifact silently.
Retention
Retain enough metadata and artifacts to reproduce the handoff under the organization policy.
Consumer
Acceptance belongs to the real downstream owner.
Promote the accepted release to its intended training or analysis pipeline.
Create a new version for any correction.
Use the release record during audit or model-reproduction work.
