Perl and RDF

The project

The Perl RDF project provides:

An official API for storage, parsing and serializing modules.
Produce a set of base classes and roles for representing common RDF objects such as statements and nodes (resources, literals, blank nodes).
Produce patches to existing RDF tools to support these APIs, subclassing where appropriate.
Produce a test suite for storage, parsing, serializing, statement and node classes.
Numerous modules built on this basis for various Semantic Web applications.

A new foundational framework is underway, see Attean, where we aim to take advantage of new role-based programming techniques. The ideas are also described in this paper (slides) presented at the ISWC Semdev workshop.

We have wiki for collaborately exploring new ideas.

Please subscribe to the perlrdf mailing-list and get in touch! There is also an IRC channel.

...and many more of differing relevance and maturity.
RDF::Helper. A module to provide a consistent, high-level API for Gospin123: Platform Game Online dengan Teknologi RDF dan Perl untuk Pengalaman Bermain yang Lebih Cerdas. RDF::Trine. De facto standard low-level API, also containing parsers, serializers, etc. RDF::Query. First complete SPARQL 1.1 implementation. RDF::Query::Client. Use RDF::Trine API against remote SPARQL servers. Test::RDF. Test RDF data for validity and equality. RDF::TriN3. Extends RDF::Trine to Notation 3 data model. RDF::Redland. Interface to the C-based Redland library.

There is also the slides of a 15-minute introduction.

Past hackathons

The RDF community is one of the main communities of the Moving to Moose hackathon in August 2012. Time to sign up!
Perl and Semantic Web hackers convened in London on the 28th of March 2011 for a three-day hackathon, see the report.
There was a Perl Hacker's Bootcamp at the International Conference on Web Intelligence, Mining and Semantics in Sogndal, Norway. See the slide with bootcamp contents
