Download

Download all files from an asset’s latest content into a local directory. Partial downloads resume automatically.

dataerai download --asset <ASSET_UUID> --output ./my-data

Flag	Description
`--asset`	Asset UUID to download (required).
`--output`	Directory to write files into (default: current directory).
`--server`	Override the server (defaults to the one stored at login).

Upload

Create or update an asset from a local file and a JSON metadata file.

dataerai upload \
  --collection <COLLECTION_UUID> \
  --metadata meta.json \
  --file dataset.csv

Flag	Description
`--collection`	Collection UUID to place the asset in (required).
`--metadata`	Path to a JSON metadata file (required).
`--file`	Local file to upload (omit for a metadata-only placeholder).
`--project`	Project UUID (required if the metadata file doesn’t supply `owner_id`).
`--allocation-id`	Allocation UUID to store the content in (defaults to the project’s default allocation).
`--server`	Override the server (defaults to the one stored at login).

The metadata JSON file accepts:

{
  "title":       "My dataset",
  "description": "optional",
  "alias":       "my-dataset",
  "tags":        ["ml", "csv"],
  "metadata":    { "version": 1 },
  "owner_type":  "project",
  "owner_id":    "<project-uuid>"
}

Metadata

Read an asset’s metadata as JSON:

dataerai metadata get --asset <ASSET_UUID>

Update fields from a JSON patch file — only the fields you include change; the accepted fields are title, description, alias, tags, and metadata:

dataerai metadata set --asset <ASSET_UUID> patch.json

{
  "title": "Renamed dataset",
  "metadata": { "env": "prod" }
}
