CWIC client
IDN/CMR
(metadata registry) 3
1. Data provider registers collections to be searchable through CWIC in IDN/CMR
2. CWIC synchronizes from IDN/CMR for registered collections
3. CWIC client performs first-step search for collection metadata (granule metadata endpoint)
4. CWIC client performs second-step search for granule metadata (data access options)
5. CWIC delegates CWIC client’s request by searching against back- end data provider
6. CWIC client accesses (order/download) granules through endpoints (native access protocols) returned in CWIC metadata
