Operators of publishing registries can use this service to request a re-harvest of their registry by pasting in their registry's IVOID below. If you paste in the magic value ``ivo://ivoa.net/rofr``, we will also fetch new registries from the RofR. You usually want to use this when you want to see the effect of some change in your registry on, say, TOPCAT. Note that you cannot start a full re-harvest of a registry from this interface. Contact the operators if you think you need that.
