 # Collection
 
-We start the collection process by scraping **10500** public repositories using the [GitHub API](https://docs.github.com/en/rest/search/search?apiVersion=2022-11-28). We specifically look for repositories released under a strong copyleft license such as **GPL-2.0**, **GPL-3.0**, or **AGPL-3.0**. We use copyleft licenses to ensure our dataset is not contaminated with training data from Stack v2. This issue occurred with other publicly available file-level code datasets, including Stack v1, which claimed to contain only permissively licensed code, however, they were [contaminated with copyleft-licensed code](https://dl.acm.org/doi/10.1145/3650105.3652298). Stack v2 also [claims to exclude copyleft-licensed code](https://arxiv.org/abs/2402.19173) due to community stance uncertainty and its low volume. Nevertheless, we still deduplicated our dataset against Stack v2 to ensure there was no overlap and that our data was safe for training.

By selecting an extra **500** repositories we can ensure that we collected at least **10,000** repositories as some repositories can be deleted/made private between fetching the list of repositories, and the actual downloading of the content.

 We extract repositories **created** up until **April** **2024** in **decreasing order** of their **star counts**. To avoid **GitHub rate limits**, we use **timeouts** and **pagination** to fetch the repositories.
 The search is based on the **repository license type**, **star count**, and **creation date**.
