OpenSearchlight: a JavaScript OpenSearch client library

[Ian Truslove]

Hi all, I just wanted to highlight that we (at the National Snow and Ice Data Center) have released a JS library that provides an API around OpenSearch services.  It's still in 0.x release status, but it is fully functional.  Point it at an OSDD, specify template parameter replacements and content type, and provide a callback to get the results.

Hope this is of use to you. Please let us know if you have any suggestions or see any bugs.

Cool!  Does it also support the draft Time and Spatial extensions to OpenSearch?

Hi Chris, in a simplistic way, yes it does.  Some code taken from one of our apps:

query.set("searchTerms", st)

.set("geo:box", osParams.geoBoundingBox.toOpenSearchString())

.set("geo:relation", osParams.osGeoRel)

.set("time:start", osParams.osDtStart)

.set("time:end", osParams.osDtEnd)

By simplistic, I mean "unaware of the semantics of XML namespaces".

Very cool! How are you working around same-origin policy restrictions?

[Ian Truslove]

Hi DeWitt, thanks!

Getting around same-origin isn't an issue for us - our client app is hitting our own data services on the same origin.  Obviously that's not really the most useful; HTML5 CORS is on the todo list in the back of my head, but not done yet.  I'd like to bundle a functional app with the lib source that hits our data services, but there's infrastructure to put in place first.

Makes sense. And you're right, this could still be very useful for people building webapps against their own search service.

When you have a chance, you may want to link to it from http://www.opensearch.org/Community/OpenSearch_software.

Thanks for contributing it!
