The PTS has a [[Linked Data]] / [[RDF]] interface.

See http://packages.qa.debian.org/common/RDF.html for the "RDF homepage" of the PTS.

The PTS produces RDF descriptions (as Turtle and RDF/XML) of Debian source packages (based on the same reference version as the PTS, i.e. usually the "latest" version in unstable).

Every package has a "stable" reference RDF document available (through content-negociation) at the "same" place as the human-readable variant, at {{{http://packages.qa.debian.org/SRC-PACKAGE-NAME}}}.

In practive, the HTML variant is generated (statically) by the PTS at {{{http://packages.qa.debian.org/PREFIX/SRC-PACKAGE-NAME.html}}} and the RDF variant at {{{http://packages.qa.debian.org/PREFIX/SRC-PACKAGE-NAME.[ttl|rdf]}}} (the {{{PREFIX}}} being computed depending on the source package name first letters.

Content-negociation for RDF/XML is classically done with the {{{'text/turtle'}}} {{{'application/rdf+xml'}}} content type requested (in the HTTP {{{'Accept'}}} header.

To view the Turtle document, issue : 
{{{ $ curl -L -H 'Accept: text/turtle'  http://packages.qa.debian.org/SRC-PACKAGE-NAME}}}

For other format, use 'rapper', for instance (from package 'raptor2-utils') :
{{{ $ rapper -o nquads http://packages.qa.debian.org/SRC-PACKAGE-NAME}}}

The RDF data uses the ADMS.SW 1.0 ontology, which includes DOAP properties and relations.

The structure of the RDF model is the following :

 * every source package is modeled as interlinked resources :
  * a "source packaging project" (SoftwareProject) resource : {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME>}}}
  * "source package versions" (SoftwareRelease) resources for every version of the source package known by the PTS (present in the different suites) : {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#SRC-PACKAGE-NAME_DEBIAN-PKG-VERSION>}}}
   * For one of these only (the "latest" one known by the PTS) there's, in that SoftwareRelease 2 includedAsset SoftwareReleases :
    * one for the upstream sources {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#upstreamsrc_UPSTREAM-VERSION>}}}
     * with resources for all archives of upstream sources as SoftwarePackages (typically {{{SRC-PACKAGE-NAME_UPSTREAM-VERSION.orig.tar.gz}}}) at URIs like {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#FILENAME>}}}
    * one for the Debian packaging files {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#debiansrc_DEBIAN-PKG-VERSION>}}}
     * with resources for all files comprising the Debian packaging source archive (typically {{{SRC-PACKAGE-NAME_DEBIAN-PKG-VERSION.debian.tar.gz}}}) at URIs like {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#FILENAME>}}}
    * and a resource pointing to the Upstream release (SoftwareRelease) for that version with a URI in the form {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#upstreamsrc_UPSTREAM-VERSION>}}}
  * one resource for the .dsc file at a URI like {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#SRC-PACKAGE-NAME_DEBIAN-PKG-VERSION.dsc>}}}
  * one resource for the Upstream project (SoftwareProject) {{{<http://packages.qa.debian.org/SRC-PACKAGE-NAME#upstream>}}} whith a doap:homepage if it's known by the PTS
  * resources (blank nodes at the moment) for the contributors (maintainers)
  * resources for the Ubuntu packaging project and latest release known by the PTS as SoftwareProject and SoftwareRelease
