@Singleton
 @Path(value="/pref")
public final class Preference
extends AbstractOryxResource

Responds to a POST request to /pref/[userID]/[itemID]. The first line of the request body is parsed as a strength score for the user-item preference. If the request body is empty, the value is 1.0.

Also responds to a DELETE request to the same path, which will signal the removal of a user-item association.
