# Common Pile v0.1 — Parquet Consolidated

## Description
This dataset bundles **all “raw” corpora from the Common Pile v0.1 Raw Data [collection](https://huggingface.co/collections/common-pile/common-pile-v01-raw-data-6826b454a5a6a445d0b51b37)**, converted to Apache Parquet and consolidated in a single repository.

Nothing has been filtered or modified; the only changes are:
* **Format:** original JSON → Parquet  
* **Layout:** many repositories → one consolidated dataset  
* **Extra column:** a `len_category` bucket for quick length-based filtering

Only the three original columns (`id`, `text`, `source`) are carried over; `len_category` is derived from `text` length.

## Dataset Schema

| Column | Type   | Notes                                                         |
|--------|--------|---------------------------------------------------------------|
| `id`           | string | Original document ID               |
| `text`         | string | UTF-8 plain text                                      |
| `source`       | string | Name of the originating corpus (e.g. `library_of_congress`) |
| `len_category` | string | Bucketed document length (bytes)|


## License Issues
Licensing follows the individual corpora.

While we aim to produce datasets with completely accurate licensing information, license laundering and inaccurate metadata can cause us to erroneously assign the incorrect license to some documents (for further discussion of this limitation, please see [our paper](https://huggingface.co/papers/2506.05209)). If you believe you have found an instance of incorrect licensing in this dataset, please [start a discussion](https://github.com/r-three/common-pile/discussions/new) on this repository.
