You can InstallDoapfiend using distutils, easy_install or subversion. There is also a Gentoo Linux ebuild available.

Example command-line usage

Fetch DOAP for SourceForge project named ‘nut’:

$ doapfiend -s nut

You have a project’s homepage, display DOAP if any has been spidered:

$ doapfiend -o http://librdf.org/raptor/

You have the URL to a DOAP file:

$ doapfiend -d http://librdf.org/raptor/raptor.rdf

Display DOAP as RDF/XML for the SourceForge project ‘nut’:

$ doapfiend -xs nut

Display DOAP as N3 (Notation Three) for the SourceForge project ‘nut’:

$ doapfiend -ns nut

Example library usage

Use a Freshmeat project name to fetch and display DOAP:

>>> from doapfiend.doaplib import get_by_pkg_index

>>> print get_by_pkg_index('fm', 'nut')

Get some DOAP and access its metadata:

>>> from doapfiend.doaplib import get_by_pkg_index, load_graph
>>> doap = load_graph(get_by_pkg_index('fm', 'nut'))
>>> print doap.name
'nut'
>>> print doap.created
'2008-04-19'

Use a project’s homepage to fetch DOAP and print the RDF/XML. Note there may be more than one DOAP profile out there; we just use the first found in our example.

>>> from doapfiend.doaplib import query_by_homepage, print_doap
>>> url = query_by_homepage('http://news.tiker.net/software/tagpy')[0][1]
>>> print fetch_doap(url)

Same as above but display DOAP in human readable text:

>>> print_doap(fetch_doap(url))
