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.
Benno, Just an fyi...To get the DIF, you just need to use this url: http://gcmd.nasa.gov/getdif.htm?entry_id where entry_id is the GCMD entry_id. In the case of HELLERMAN, it would be: http://gcmd.nasa.gov/getdif.htm?HELLERMAN This returns the html version of the DIF. You could also use the http api and construct a complete query in the url: http://gcmd.nasa.gov/servlets/md/get_entry_ids.py?query=[Project:Short_Name='DODS']+AND+[Source_Name:Short_Name='NOAA*'] you can also retrive the "raw' DIF that can be edited or even an XML DIF by specifying the format in the URL.
