Tools in Support of a National DMAC Derrick Snowden NERACOOS/ODP Annual Meeting 26 Sep 2012

IOOS DMAC Subsystem Implementation Guidance a) Open Data Sharing: b) Provision of Data to WMO GTS: c) Service-Oriented Architecture (SOA): d) Recommended Data Access Services: e) Common Data Formats: f) Common Vocabularies and Identifiers: g) Metadata: h) Storage and Archiving: i) Data Management Planning and Coordination: j) IOOS® Maturity Levels and Certification Standards: k) Consideration for Long-term Operations: ide.noaa.gov/wiki/index.php?title=IOOS_DMAC_Subsystem_Implementation _Guidance

Data Integration supports frameworks we can build useful services upon. 3 Illustrates the Publish, Find, Bind Pattern. OGC Reference Model (OGC r7) Discover Data/Service Register Data/Service Data/Service Registry Use Data/Service Data/Service e.g. Regional Association Data/Service Consumer

Technologies applied to Data Registries/Catalogs 4 ISO 191** Geospatial metadata standards ncISO – Harvester supporting netCDF  ISO 191** translation ESRI Geoportal Server GI-CAT, Geonetwork Opensearch, OGC CS/W ERDDAP THREDDS

The growing list of clients 5 nctoolbox Environmental Data Connector ERDDAP Javascript library for SOS Python library for SOS Java library for SOS IAI Proteus SOS Client and Community Hub

Data Services Tools and Technologies 6 netCDF – Climate and Forecast conventions – OPeNDAP THREDDS (data cataloging and distribution with a flexible plugin environment) Hyrax (opendap.org) Sensor Web Enablement (Framework/family of services, encoding standard, family of services) SOS (OGC Sensor Observation Service) ERDDAP W*S (OGC Web * Service, primarily WMS)

Technologies applied to Data Services: the short list 7

gridded model outputs HF radar In situ observations Points, Profiles, Collections, Trajectories Structured Grids (increasingly unstructured grids)‏ CF/ACDD SOS (Sensor Observation Service)‏ DAP (Data Access Protocol) WMS (Web Map Service)‏ THREDDS ISO (TDS Catalog  ISO 1911*)‏ WCS (Web Coverage Service)‏ Etc… ncSOS: A THREDDS plugin implementing the SOS interface Courtesy Eoin Howlett
