We are working with the MPAT project, http://mpat.eu 
The Telecom ParisTech team has a few specific contributions on github:
- mpat-explorer plugin, to explore the depths and details of the MPAT instance
- mpat-importexport plugin, to import and export pages and exchange them between content editors
- mpat-getinfofrompage, to recreate an importable package from a published MPAT page
- mpat-tvdebugserver, to help with debugging MPAT application even on relatively old TVs
- mbop-remover, to help with a bug relevant for old MPAT users
