# Usage |
|
|
- `ds.parquet` : Aggregated dataset information. |
|
|
- `co/` directory: Configuration rows each include a structure, calculated properties, and metadata. |
|
|
- `cs/` directory : Configuration sets are subsets of configurations grouped by some common characteristic. If `cs/` does not exist, no configurations sets have been defined for this dataset. |
|
|
- `cs_co_map/` directory : The mapping of configurations to configuration sets (if defined). |
