How to access archival data at NODC in under 5 minutes! NODC ↔ Data Consumers Steve Rutz NOAA/NESDIS National Oceanographic Data Center NODC Observing Systems Team Leader June 21, 2011
Archival Information Package (aka, NODC Accessions) • Accession Tracking Database • Tracks metadata relevant to data discovery • Records version control for long term stewardship • Producer's SIP • Data set is preserved exactly as submitted to Archive • Archive's supplementary files • Browse graphic of geographic coordinates • FGDC metadata records • May generate more interoperable file formats of the data for long-term stewardship
Discovery Discovery Human to Machine Interfaces Machine to Machine Interfaces Discoveryis enabled through numerous interfaces designed for both humans and their machine clients. Human-to-machine interfaces include government-mandated generalized portals like Data.gov and Geospatial One-Stop (GOS) Google Data.gov GOS OAS Geoportal Server Web App CSW Geoportal Server REST API OpenSearch SRU/ISO23950 The NODC Ocean Archive Discovery services are available for ALL of the NODC Archive holdings, but better metadata supports better discovery!

Access and Use Get your DIPs! LAS, GIS, KML Enhanced online access, visualization, and analysis tools: These capabilities require more structured metadata and standardized file formats, so are available to the fewest archive holdings. WCS, WMS, SOS DAP Data Access Protocol (DAP): Requires standard file formats so is available to fewer archive holdings. FTP and HTTP Basic FTP/HTTP access for all Archival Information Packages (AIP) in the NODC Ocean Archive: These distribution methods have no format or metadata requirements so they work for all archive holdings, but they provide only basic download capability.

(or your supervisor’s, or the NODC you knew while in grad school…)
