Fetch Project Info


oss-directory contains structured data on as many open source projects as possible, enumerating all artifacts related to the project, from source code repositories to published packages and deployments. You can get the data via our npm library, python package, or downloading the data directly from GitHub.

Directory Structure

The OSS Directory is organized into two main folders:

  • ./data/projects - each file represents a single open source project and contains all of the artifacts for that project.
    • See ./src/resources/schema/project.json for the expected JSON schema
    • Files should be named by the project name
    • A project's name must be globally unique. If there is a conflict in chosen name, we will give priority to the project that has the associated GitHub organization
    • In most cases, we adopt the GitHub organization name as the name. If the project is not associated with a GitHub organization, you try to use the project name followed by the repo owner as the name.
  • ./data/collections - each file represents a collection of projects that have some collective meaning (e.g. all projects in an ecosystem).
    • See ./src/resources/schema/collection.json for the expected JSON schema
    • Collections are identified by their unique name

Using as a library

We have also published this repository as a library that you can use in your own projects. This is useful if you want to build a tool that uses the data in this repository or perform your own custom analysis.

We have libraries for JavaScript and Python. We don't store the entire dataset with the package. Under the hood, this will clone the repository into a temporary directory, read all the data files, validate the schema, and return the objects. This way, you know you're getting the latest data, even if the package hasn't been updated in a while.

Note: These do not work in a browser-environment

JavaScript library
