Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Re: granularity I don't have an answer on what level of granularity is appropriate - only to mention that the harvester will have simple check boxes that allow you to harvest services, collections and atomic dataset metadata - its a device to which other options could be added. The whole concept of searching/identifying and displaying hierarchical relations between dataset metadata records as well as relationships between services records and the datasets they deliver is still at a very early stage of development (at least in GeoNetwork :-)).
