[Esip-discovery] java api for opensearch

[Eric Rozell]

FYI, I have been using an OpenSearch API from the Abdera OpenSearch extension (also an Apache project).  It has some good features, but is definitely lacking in some areas.

One of the failures in particular is that the API should support retrieval of XML attributes by namespace.  For instance, if I want to read the role attribute of a opensearch:Query tag, it should be retrievable as opensearch:role (rather than just the local part of the curie).

I think we may also need this kind of attribute retrieval feature for the ESIP Discovery if we come up with some new Query tag attribute for "valid parameters" (e.g., esip:validparams).  

Looking briefly at the source code for Terradue, it looks like the OpenSearch Description API has been encapsulated in a class (com.terradue.jcatalogue.client.CatalogueDescription).  I think it would make a lot more sense to have a very generic OpenSearch API as its own separate project, rather than coupling with this jcatalogue project for Catalogue Satellite products.  Anyone know of any such projects?

Cheers,
-Eric
