DOAP

Description of a Project

Summary

Description of a Project

Description of a Project (DOAP) is an RDF Schema and XML vocabulary designed to describe software projects, particularly free and open-source software.

It was created and initially developed by Edd Wilder-James (Edd Dumbill) to convey semantic information associated with open source software projects.

Adoption

There are currently generators, validators, viewers, and converters to enable more projects to be able to be included in the semantic web. In 2007 Freecode listed 43 000 projects as published with DOAP. It was used in the Python Package Index but is no longer supported there.

As of 2025, inclusion of DOAP files is common in the source code of GNOME projects.

Major properties include: homepage, developer, programming-language, os.

Examples

The following is an example in RDF/XML:
