Package-URL

A minimal specification and implementation of PURL (Package URL) and VERS (Version Range Specifier)
README.md

Welcome to Package-URL on GitHub

Package-URL is an open source community that develops and supports the Package-URL (PURL) and Version Range (VERS) specifications.

  • The PURL specification is an Ecma standard: ECMA-427.
  • The VERS specification will be proposed as an Ecma standard in 2026.
  • Both standards are managed by the Ecma Technical Commmittee 54

We currently host repositories for 12 tools that implement PURL and 2 that implement VERS.

We welcome your participation. Some ways to get started are:
