An embodied AI training dataset needs an explanation of what a particular run was allowed to use. Original recordings, selected episodes, prepared representations, and later corrections can belong to different versions. A folder name alone may not explain the relationship.
The database can be useful for cataloging and governing that information, but the choice should follow the training workflow. OceanBase is worth evaluating for suitable structured metadata and operational requirements; it should not be presented as a proven replacement for every media storage or training input system.
Describe the selected dataset, not only the collection
A collection may continue to grow while one training run uses a bounded selection. Record the source material and selection rule for that run rather than assume the current contents of the collection reproduce it.
Distinguish the original recording from prepared training material. A corrected label, excluded episode, or changed preparation method can affect the selected dataset without changing the identity of the original source.
The purpose is traceability at the level the project needs. This article proposes a high-level dataset record, not a robotics training algorithm or a guarantee that a particular model will learn safely or perform well.
Give the manifest an accountable structure
Use a record that connects the selected material to the decisions behind it.
| Manifest area | Question to answer | Evidence to retain |
|---|---|---|
| Source identity | Which recordings and related assets were selected? | Stable references and relevant source versions |
| Selection | What was included or deliberately excluded? | Saved selection and accountable owner |
| Preparation | Which transformations or labels were applied? | Named preparation version and approved changes |
| Usability | Can the intended reader locate and interpret the material? | Format and access check in the actual workflow |
| Correction | What later finding affects this selection? | Linked issue and revised dataset decision |
These categories should be adapted to the organization’s approved data handling and access requirements. They are not a universal statement of legal rights to use every recording.
Use a concrete format to expose the relationships
LeRobotDataset v3.0 documentation provides an example that separates tabular signals, video, and metadata. It explains episode relationships through metadata rather than treating every filename as a complete episode description.
That is a useful illustration of why the manifest matters. It is not a requirement that every embodied AI project adopt that format, nor evidence that every database can read its training inputs directly.
Use the format and release actually chosen by the team. Keep the documented example’s version visible instead of promoting a page about one format into a universal or latest-release claim.
Place OceanBase and other platforms in their actual roles
The OceanBase AI solution page offers a starting point for an operational data proposal. Ask which metadata, approvals, and dataset relationships the selected database arrangement will own.
Databricks machine learning documentation describes a broader training workflow context. Amazon SageMaker’s training input guidance provides concrete information about supported input paths for that service.
Compare the complete chosen workflow rather than treating these as identical database products. The catalog database, original asset store, prepared dataset, and training service can have different responsibilities even when some are integrated.
Reconstruct one selection before scaling the program
Choose a bounded dataset and ask another authorized team member to locate the selected records and assets using the manifest. Check the approved access and intended reader, not just whether a database query returns references.
Then introduce a controlled correction or exclusion. Observe how the manifest distinguishes the earlier selection from the revised one and how future use follows the approved decision.
Record missing assets, ambiguous labels, and inaccessible inputs as evidence gaps. Do not claim reproducibility because the selection query can be run again against a collection that has since changed.
Keep training performance separate from this acceptance exercise. A readable, traceable selection is valuable evidence, but it is not a measured model-quality result.
Maintain the record across later findings
Give dataset selection, preparation, and access decisions named owners. The record should make it possible to identify affected selections when a source or label is corrected.
OceanBase can be a useful operational foundation when its supported data model fits these catalog and governance responsibilities. Another database or platform may fit the selected training workflow better.
The manifest also needs a deliberate answer for mutable references. If a location can later contain replaced material, a reference to that location alone may not identify what the run originally selected. Ask the chosen asset and catalog arrangement to demonstrate how the intended version is located under the approved process. Keep that question separate from the choice of database engine; a strong catalog cannot explain an original asset that the surrounding workflow no longer identifies reliably.
The successful manifest explains what was used, why it was eligible, how it was prepared, and how a later correction changes the next decision. That gives the training team a reproducible starting point without attributing every part of the embodied AI pipeline to the database.
