    String summary 
"[Normally, the summary describes the dataset. Here, it describes 
the server.] 
The OCEANS IE -- formally approved as an OGC Interoperability 
Experiment in December 2006 -- engages data managers and scientists 
in the Ocean-Observing community to advance their understanding and 
application of various OGC specifications, solidify demonstrations 
for Ocean Science application areas, harden software 
implementations, and produce candidate OGC Best Practices documents 
that can be used to inform the broader ocean-observing community. 

Initiators: SURA (lead), Texas A&M University, MBARI, GoMOOS and 
Unidata.

Specific goals:
* Compare Sensor Observation Service (SOS) from the OGC's Sensor 
  Web Enablement (SWE) initiative to the Web Feature Service (WFS) 
  as applied to ocean data in a variety of data formats including 
  text files, netCDF files, relational databases, and possibly 
  native sensor output; (see Experiment #1 for details)
* Make use of semantic mediation via Semantic Web technologies to 
  allow plurality of identification for source types (platforms 
  and sensors) and phenomena types;
* Test aggregation services and caching strategies to provide 
  efficient queries; 
* Explore possible enhancements of THREDDS server, so that THREDDS 
  resident data sources might be made available via SOS or WFS;";

Using tabledap to Request Data And Graphs from Tabular Datasets

tabledap lets you request tabular data (for example, buoy data) and graphs of tabular data, via specially formed URLs.
The URLs specify everything: the dataset, the desired file type for the response, and the subset of data that you want to receive.
You can form these URLs by hand or with a computer program,
or (much easier) you can use the dataset's "Data Access Form" (oriented to requests for data)
or the dataset's "Make A Graph" form (oriented to requests for graphs and maps),
both of which generate the URL when the form is submitted.
tabledap is a superset of the OPeNDAP DAP constraint protocol.

tabledap request URLs must be in the form
   http://cwcgom.aoml.noaa.gov/erddap/tabledap/ datasetID fileType {?query}
For example,
   http://cwcgom.aoml.noaa.gov/erddap/tabledap/pmelTao.htmlTable?longitude,latitude,time,sea_surface_temperature&longitude>180&longitude<180.2&latitude>0&latitude<0.2&time>2007-06-01

For details, see the tabledap Documentation.
