Classify the rooms with custom properties

Hi,

I've created an index (data source: /documents/myfolder) with a taxonomy and the documents are well classificated by the taxonomy query builder.

Then I add a new data source that points to /rooms and make a query to do automatic classification but the room folders are never classified.

(looking in Trex monitor-> display queue entries says that they are indexed, that's not the problem)

My questions about this are:

Are the room folders right resources to be indexed, or have a special behavior?

Maybe my custom properties that i applyed in the taxonomy query builder are not applicable to the room folders?

Have I to create a properties in a special way to apply to a rooms?

In short, what I have to do to classify the rooms with my properties?

Thank you very much

Guillermo.
