After a coding period spread over few weeks, I just released RPP-Parser, a script to parse and generate REAPER project files.
The original concept was designed by mrlimbic for Vordio and was written in Java, he supervised me for the Lua port. It is way easier and faster than our previous version.
It was a pretty intense coding project for sure but the results are very nice: you can gerenrate a 10 000 items references project in 1s or less!
I put all the doc on the ReaTeam/Reascripts wiki, as the script is shared there, free and open source.
