Dataset Contribution

Use this subskill when the task is about packaging a new OGB-compatible dataset with DatasetSaver, generating a meta_dict.pt, or validating the layout of a submission archive.

Use this subskill when

• The task names DatasetSaver or save_graph_list / save_target_labels / save_split / copy_mapping_dir / get_meta_dict.
• The task asks how to prepare meta_dict.pt, mapping/, or a release zip for an external dataset contribution.
• The task needs a tiny end-to-end smoke of the export pipeline.

First decisions

1. Read references/workflows.md for the step order and family constraints.
2. Read references/data-formats.md for graph, split, label, and mapping directory shapes.
3. Read references/api-reference.md for the method order and parameter expectations.
4. Read references/troubleshooting.md when a shape, mapping, or zip step fails.
5. If you want a safe end-to-end smoke, run scripts/datasetsaver-tiny-smoke.py.

Main workflow

• Decide whether the dataset is graph-, node-, or link-oriented.
• Build the graph list in the format OGB expects.
• Save labels and splits in the same order that the export helper expects.
• Copy the mapping directory only after the raw and split files are present.
• Generate the meta_dict.pt and zip the prepared directory.
• Reload the tiny smoke dataset to confirm the archive structure still works.

Common routing choices

• Use this subskill for new OGB-compatible releases.
• Use the graph/node/link subskills when the user only needs to consume an existing OGB dataset, not package a new one.

What not to do here

• Do not tell the user to hand-edit the packaged release after the zip step.
• Do not assume heterogeneous ogbg export is implemented.
• Do not depend on the original checkout for final runtime guidance.
