doyoudatabnf helps you download data.bnf.fr RDF dumps and load it on a personnal 4store triple store and SPARQL server. This set of RDF files is a sample of French national library catalog in RDF. It's high quality Open Data [fr].

Prerequesite

You need 10 Go on your harddrive, a *nix computer (*BSD, GNU/Linux, possibly Mac OS X...) with wget and 4store installed. We use also use git in this tutorial. On Ubuntu you can install it with:

sudo apt-get install wget 4store git

It seemed 4store defaults it's files location to /var/lib/4store, but Ubuntu doesn't create the directory. Here's a way of creating it, letting all users access it (same way you can access the /tmp dir):

sudo mkdir /var/lib/4store
sudo chmod 1777 /var/lib/4store

Import data.bnf.fr RDF files on your desktop

git clone git://github.com/nlegrand/doyoudatabnf.git
cd doyoudatabnf
./doyoudatabnf

Launch the 4store triple store backend:

4s-backend databnf

You may have to wait for something like half an hour for the process to complete. Once finished, you can test it:

$ 4s-query -s -1 -f text -P databnf <sparql/totaltypes.sparql 
?type	?total

Yummy! You can launch a SPARQL server:

4s-httpd -s -1 -p 8000 databnf

and go to the HTML sandbox.

About 4store

You'll love 4store if you like straightforward application in the *nix spirit. It seemed to me like the easiest triple store to install and use.

Start and stop

When you're done playing with 4store, you can stop the backend this way:

pkill -f '^4s-backend databnf$'

To launch it again (or after a computer reboot):

4s-backend databnf
