DOAP

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

It was created and initially developed by 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. Freecode's 43 000 projects are now available published with DOAP.[1] It was used in the Python Package Index but is no longer supported there.

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

Examples

The following is an example in RDF/XML:
