Hi Florent,

if you encounter bugs in Hormiga, which will very likely happen as I
didn't have time yet to use it in a real project, please catch me on
IRC (abustany) or by mail. I'll try to be quick in fixing them.

As for your questions:
- passing an array of subjects seems a sane idea, they don't have to be
  InformationElement though, rdfs:Resource should be fine.
- about numericRating, if you look at
  http://www.semanticdesktop.org/ontologies/nao/#mozTocId4771, you can
  see that the value should be between 0 and 10, 0 meaning "unset"

Cheers

Adrien
