Political Memory : Implemented Software Framework

Pages on this wiki related to Political Memory are based upon a Berkeley DB XML database (BDB XML). Some Perl scripts are run to create this database, to extract informations from this database in order to crate wiki pages, or to update this database from updates made on the wiki pages. Hence these wiki pages can be viewed as a frontend to this database. However there is no real time synchonizations between the database and the wiki pages. Updates of the wiki from the database, and conversely, are frequently made in a semi-automatic way.

A dump of the database, the directory tree, and Perl scripts can be downloaded freely. These scripts are licensed under GNU General Public License version 3 or higher.

Database Setup

• Untar directory tree tarball (tar zxvf skeleton_memoire_politique.tgz)
• Download Berkeley DB XML.
• Install BDB XML with Perl support (sudo sh buildall.sh --enable-perl)
• Untar dump of the database (tar zxvf dumps_memoire_politique.tgz)
• Load the following containers from this tarball:
  • container for MEPs: dbxml_load -h <target_directory> -f dump/en_meps.dump en_meps.dbxml
  • container for the votes : dbxml_load -h <target_directory> -f dump/votes.dump votes.dbxml

You can access to this database with shell (dbxml) provided by BDB XML (see tutorial) or by writing your own programs in C++, Java, Perl, Python, PHP or Tcl. Of course, the Perl scripts described below can be use as examples.
