Analysis and Display Software
Compound Documents
i.e.,electronic publications with embedded
pointers to datasets and tools
Discovery CenterCatalog Systemse.g. DLESE,
NSDL, GCMD
e.g. IDV, VGEE,LAS, INGRID, IDL, GDS
Discovery and Usage Metadata Middleware e.g.
THREDDS catalog generators, servers, harvesters
Data Server Software e.g. FTP, OPeNDAP, ESG,
OpenGIS, Web services
Data Storage System e.g., Disk, RAID, Mass

Browser-base Thin Client Access

• LDEO/IRI web site publishes catalog of datasets
  available on server at UCAR
• Catalog resides and is updated at UCAR
• Browsing of datasets on UCAR server from LDEO
  server
• Also enables analysis and display of datasets on
  UCAR server using tools on LDEO server
