In a blog posting earlier in January Richard Pop descibed the difficulty to get started with Linked Data for the average programmer: „there is a new format (RDF), new query language (SPARQL) and new code libraries to learn and install (if you can find them in the first place)“. For this reason Pop created a challenge to come up with documentation for the basic steps of developing a Linked Data/RDF/SPARQL application. You can find contributions by Bill Roberts, Christopher Gutteridge, Pezholio, Gunnar Aastrand Grimnes, Tom Morris, Jeni Tennison (and here), Niklas Lindström, Felix Ostrowski, and John Goodwin. Meanwhile there are £50 prizes for solutions in PHP, Ruby, and Phython.
I have engaged in RDF since years, but mostly from a theoretical point of view. This year I started creating Linked Data applications with RDF::Trine, a powerfull programming library by Gregory Williams to handle RDF data in Perl (see more at perlrdf.org). I contributed some minor patches to further simplify usage. Next month I will write a tutorial on how to create an RDF based application in Perl. Meanwhile I work on a Perl module (limited preview) to create classifications and thesauri in SKOS/RDF.
