Voici une traduction en français d’un court document introductif au Linked Data, originellement écrit par Luca Matteis :

Bonne lecture.
I’ll be presenting “Authoritative linked data descriptions of debian source packages using ADMS.SW” at OSS 2013.
Here’s the abstract :
The Debian Package Tracking System is a Web dashboard for Debian contributors and advanced users. This central tool publishes the status of subsequent releases of source packages in the Debian distribution.
It has been improved to generate RDF meta-data documenting the source packages, their releases and links to other packaging artifacts, using the ADMS.SW 1.0 model. This constitutes an authoritative source of machine-readable Debian “facts” and proposes a reference URI naming scheme for Linked Data resources about Debian packages.
This should enable the interlinking of these Debian package descriptions with other ADMS.SW or DOAP descriptions of FLOSS projects available on the Semantic Web also using Linked Data principles. This will be particularly interesting for traceability with upstream projects whose releases are packaged in Debian, derivative distributions reusing Debian source packages, or with other FLOSS distributions.
Update: If you are interested, a preprint is available here in HTML form. See also previous installments on ADMS.SW in this blog.
Update: The slides of the presentation I made at Isola are here.
I’ve given a lightning talk at Distro Recipes 2013 about what I’ve been working on for several months: adding Semantic meta-data to Debian PTS, and stuff.
Here are my slides :
And the same, downloadable in PDF.
Thanks to the Hupstream staff and other participants of Distro Recipes for the interesting discussions and contacts. Looking forward to participating to the next edition.
The Debian PTS now speaks the Turtle representation format for the export of RDF meta-data about Debian source packages.
Alongside HTML pages for humans, and the RDF/XML that had already been added to it this means that a new flavour of RDF is now available.
The Turtle format offers the benefits of both machine-readable meta-data, and a somehow human readable textual format too.
For instance, you may check the apache2 Turtle meta-data from the command-line with :
$ curl -L -s -H "Accept: text/turtle" http://packages.qa.debian.org/apache2
Here’s a link to a colorized HTML preview of http://packages.qa.debian.org/a/apache2.ttl.
Under the hood, the XSLT stylesheets of the PTS have been reworked to produce the Turtle format by default, and later convert them to RDF/XML.
Every Debian source package then has a reference URI in the Linked Data word, in the form http://packages.qa.debian.org/PACKAGE_NAME
, that redirects, through proper content-negociation (the HTTP Accept
header) to the HTML, RDF/XML or Turtle documents. For apache2, these are, resp. at http://packages.qa.debian.org/a/apache2.html, http://packages.qa.debian.org/a/apache2.rdf and http://packages.qa.debian.org/a/apache2.ttl.
The meta-data uses the model of the ADMS.SW ontology (1.0), and the content has also been slightly updated to make it more conformant to the ADMS.SW specifications (checks done with the ADMS.SW validator).
Let’s hope this makes RDF more familiar to Debian folks, and allows more Linked Data interlinking with other resources about FLOSS packages.
Maybe this could be of interest to a few of my readers who may have missed the announcement, in particular for ones related to forges which will be deployed for private administrations in Europe.
The recently started ADMS.F/OSS project is described as :
ADMS.F/OSS is an XML and RDF vocabulary to describe software, in
particular free and open-source software (F/OSS), making it possible to
more easily search and discover software. The ADMS.F/OSS specification is still under development.
It is developped in the frame of an EC (European Community) programme for interoperability between public administrations (more on the page above).
I’ll try and participate to the working group, bringing in some feedback from the efforts on similar issues conducted during the (now over) COCLICO project.
Hope this helps.
