Web Services – key to interoperability RESTREST –Service description: URI path – WADL –Interface: many custom clients derived from simple uniform pattern –Extensible: expose new resource –Semantics: browser defined service methods (get,post,delete,etc.) –Use case: navigate URI directories/hyperlinks –Entry: easy, http/ftp construct, no language dependencies SOAPSOAP –Service description: WSDL –Interface: many custom clients from a single endpoint (complex) –Extensible: add new service methods in WSDL –Semantics: implicit operations definition and implementation –Use case: SOA (publish – find – bind) –Entry: not easy, language dependencies

NCDC Services Daily DataDaily Data –COOP, ASOS, AWOS for US networks –Up to 50 variables observed per day (station dependent) –Output types: csv, xml –1870 to present –Last observation: available after final QC ~2 weeks Integrated Surface DataIntegrated Surface Data –Hourly observations from global networks –Potentially 35 variables observed per minute –Output types: csv, xml, waterML –1900 to present –Last observation: yesterday’s data

NCDC Services Global Summary of the DayGlobal Summary of the Day –Integrated Surface Data (global network) –12 variables available –Output types: csv, xml, json –1900 to present –Last observation: yesterday’s data Drought IndexDrought Index –COOP, ASOS networks –15 variables available –Output types: csv, xml, json –1890 to present –Last observation: updated weekly DEMO
