Vr. RBO with THREDDS data store

Paths & URLs • THREDDS server http: //spidrd. ngdc. noaa. gov/thredds • THREDDS data directory spidrd: /mnt/sdb 2/devel/content/thredds/vir bo • Vi. RBO http: //spidrd. ngdc. noaa. gov/virbo

Net. CDF granules • Store catalog level metadata in VO • Store granule level metadata in a section of the VO database • Search the granules metadata using product-specific web form (link from a catalog metadata record) • Upload Net. CDF files into the Data Store • Access data granules using Open. DAP

Vi. RBO file upload

Time series as THREDDS joins of Net. CDF files • Store catalog level metadata in VO • Create a folder in the Data Store to store multiple Net. CDF files • Create a folder. ncml file in the Data Store to join multiple Net. CDF files into one time series “database” • Subselect (hyper-slab) time series from the joined “database” using Open. DAP protocol and clients (link from catalog metadata record)

Enhanced THREDDS Catalog • Adds XML (NCML) metadata file to the binary granule • NCML metadata can be used in WCS or rendered into HTML for a web client • NCML granule data CAN NOT be searched using x. Query or x. Path

Open questions • What granule-level metadata schema? – – NCML? Can’t get it directly from THREDDS… CDFML? Can’t get only header using CDF 2 XML… ECHO? No software extractors… SPASE? No CDFML 2 SPASE, no use cases/samples • How manipulate folders in the THREDDS Data Store? • What Open. DAP viewer to use as default?
