RDF dumps are usually about weekly, but sometimes may not occur for some weeks if there is server downtime, or the process is switched off or delayed because the CPU cycles were needed for some other task. There is a lot of work going on at the moment, so don't rely on any new RDF anytime soon.
Additionally, the ODP search is not being updated regularly at the moment as it is low priority among many other jobs.
The public side of the ODP is also frozen, now with two week old data. The editor side is fully operational at this time. The public side may not be relinked to the main database for another week or two yet.
