Description:

 """Get remote resource information. Creates a local directory for the resource if this is the first access to the resource. Downloads the resource Json representation and writes it into a .json file in the cache directory. Raises ValueError if resource is not cached and does not exist. If the resource no longer exists on the server but in the local cache, a reference to the local copy is returned and the value of the is_active flag is False. Parameters cache_id : string Unique cache identifier resource_url : string Url of the resource Returns ------- (string, Json, Boolean, string) Returns a 4-tuple containing local resource directory, the Json object representing the resource, an active flag indicating if the resource still exists on the remote server or only in the local cache, and the resource unique cache identifier.
