Last improvement to milestone 0.1. Today we have :
* sources from .xml
* redundancy check and dealt with
* index key form : 00000000-n#lemma_with_space#lng

Nodes produced does not contain synset, should we add them ?

We just saw that http://compling.hss.ntu.edu.sg/omw/ now give us xml files. Should we now head toward lmf support or try to test db ( consistency, translation gaps ... ) ?
