Overview OpenSearch Methodology Description Document Search Document Parameters in a Search operation request Search operation request URL parameters Best Practice Demonstrator ETS Resources OGC TC Geneva / HMA-S /FP

OpenSearch Specify how to query a web resource & additional metadata Description documents Contain parameterized URL templates that indicate how the search client should make search requests Search clients to learn about the public interface of a search engine OpenSearch provides a way to define where that search term goes. http://www.example.com?q={searchTerms} Description element provides some basic metadata about Contents of the service Contact information pertaining to it Set of URL Templates which illustrate the parameters accepted by the service and the variety of output formats Request interface Simple, Consisting of a description of a HTTP GET request Series of optional key-value parameters that can be used to constrain the search.

OpenSearch Description The OpenSearch description document for the satellite Tasking is an aggregation of the information available via the GetCapabilities, the DescribeTasking, the DescribeSensor operations of the EO-SPS standard. SPS GetCapabilities SPS DescribeTasking SPS DescribeSensor OpenSearch Description OGC TC Geneva / HMA-S /FP

OpenSearch Search SPS GetFeasibility SPS GetTask OpenSearch Search The OpenSearch search operation is mapped to the GetFeasibility operation, the response of the search operation provide for each of the results a summary and the link to their dedicated EO-SPS GetTask operation.
