This dataset contains seven csv files:


A project is a piece of software available on any one of the 34 package managers supported by


A version is an immutable published version of a Project from a package manager. Not all package managers have a concept of publishing versions, often relying directly on tags/branches from a revision control tool.


A tag is equivalent to a tag in a revision control system. Tags are sometimes used instead of Versions where a package manager does not use the concept of versions. Tags are often semantic version numbers.


Dependencies describe the relationship between a project and the software it builds upon. Dependencies belong to Version. Each Version can have different sets of dependencies. Dependencies point at a specific Version or range of versions of other projects.


A repository represents a publically accessible source code repository from either, or Repositories are distinct from Projects, they are not distributed via a package manager and typically an application for end users rather than component to build upon.

Repository dependencies

A repository dependency is a dependency upon a Version from a package manager has been specified in a manifest file, either as a manually added dependency committed by a user or listed as a generated dependency listed in a lockfile that has been automatically generated by a package manager and committed.

Projects with related Repository fields

This is an alternative projects export that denormalizes a projects related source code repository inline to reduce the need to join between two data sets.
