This project provides a set of Perl modules to create simple RDF-based web applications. It is in a very premature state of development and will not be published as "official" Perl module on CPAN before further testing and discussion. If you are interested in Perl and RDF in general, you should have a look at the RDF and Perl page.
The priority of RDF::Light is ease of use, but not 100% conformance with every aspect of the RDF technology stack.
Make sure you have installed Perl and you have
a command line interface (the following statements after $ are commands). I
recommend cpanminus
to install required Perl modules. To use all of RDF::Light you need:
With cpanminus you should be able to install these with the following commands:
$ cpanm RDF::Trine
$ cpanm Task::Plack
$ cpanm Template
Download RDF::Light from github via the web interface (the "Downloads" button at the right) or clone via git:
$ git clone git://github.com/nichtich/RDF-Light.git
$ cd RDF-Light
Once you have extracted all files in a directory you can run one of the example applications:
$ plackup -Ilib -r examples/countries/app.psgi
$ plackup -Ilib -r examples/lobid/app.psgi
Browse to http://localhost:5000 and you should get an HTML page with a list of country names as example. Have a look at the source code in the examples directory, modify them and see the results, and read the documentation.
RDF::Light consists of the following (sets of) classes, that can each be used independently. Some of them may get renamed or merged to existing Perl modules:
- RDF::Light - a PSGI Middleware for Linked Data
- RDF::Light::Source - a method to combine sources of RDF data
This list is not complete or stable. If you have suggestions or comments, you are welcome to submit an issue!
