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.
There are currently generators, validators, viewers, and converters to enable more projects to be able to be included in the semantic web. Freshmeat's 43 000 projects are now available published with DOAP. It is currently used in the Mozilla Foundation's project page and in several other software repositories, notably the Python Package Index.
Major properties include: doap:homepage, doap:developer, doap:programming-language, doap:os
The following is an example in RDF/XML:
Other properties include Implements specification, anonymous root, platform, browse, mailing list, category, description, helper, tester, short description, audience, screenshots, translator, module, documenter, wiki, repository, name, repository location, language, service endpoint, created, download mirror, vendor, old homepage, revision, download page, license, bug database, maintainer, blog, file-release
and release.
There's war in the heavens
Rebellion on high
the son of the morning
Descends from a black sky
Severed and broken
His wings burned to dust
His coverings of diamonds and gold
In a moment in time dissolve to rust
Thunder and lightning
Shatter the night
The dragon of darkness
Appears cursed by the keeper of the light
The dark is chosen
The scroll has been sealed
Hidden in verses of prophets
His face is revealed
Songs of glory
Shout across the land
I can take you there
Child of mine, take my hand
Down through the ages
The story's been told
The daughter of wisdom
Beguiled by the serpent of old
Born into sin in a valley of thorns
Torn from enchantment and
Tossed into the eye of the storm
Heaven's garden
Made by God for man
This is paradise
Child of mine, take my hand
Glory to glory
Sin after sin
The rider of death
Pushes on to the place where
The battle must begin
Songs of glory
Shout across the land
This is paradise
Won't you take my hand
Heaven's garden
Made by God for man
This is paradise
Child of mine, take my hand
Oh, take my hand
