Description

Provide a mechanism to describe valid and invalid inputs for query elements in ESIP Discovery services.


Problem Addressed

OpenSearch does not have a mechanism for indicating valid options for search parameters. The OpenSearch Parameter extension (http://www.opensearch.org/Specifications/OpenSearch/Extensions/Parameter/1.0) has options for specifying the number of times a particular parameter may or should be included in the search request, but this does not meet our needs.


Proposed Solution

Add a validpatterns role to the OpenSearch <query> element, and specify valid values for attributes with a regular expression.

Example:

<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">
  <Url type="application/atom+xml" template="http://somedataprovider.com/?q={searchTerms}&datum={datum?}&gridSize={gridSize}&format=atom"/>
  <Query role="example" searchTerms="map" datum="WGS84" gridSize="1km" />
  <Query role="http://esipfed.org/ns/discovery/1.1/#validpatterns" searchTerms="WGS84|EGM96" gridSize="1m|10m|100m|500m|1km|10km" />
</OpenSearchDescription>
