Sometimes we need mail merge on inkscape, usually to make id card or certificate in bulk. You need to install extension on Inkscape. Find the extension here : http://wiki.colivre.net/Aurium/InkscapeGenerator.

In ink-generator directory you will find two files, generator.inx and generator.sh. Just copy them files to /usr/share/inkscape/extensions. Then on Inkscape, this extension can be accessed from Extensions menu > Misc > Generator. Using this extension, you also need csv files containing list such as name or number or so on that will be using on mail merge.
