At this summer's FDSN meeting in Montreal, EIDA and IRIS presented a prototype data center registry to be hosted on www.fdsn.org http://www.fdsn.org/. The registry contains a listing of data centers, which services are offered, and optionally which data sets are available from each. Each data center registers and controls their own entry. We anticipate this information being used by data collection software, federating and brokering systems, etc. to enhance the discovery of centers, their services and the data they offer.
At the meeting the proposal was well received with a few comments and suggestions, which have now been addressed, including the ability to include citation information for a data center.
