[Mattmann, Chris A (388J)]

Hi Eric,

Thanks for passing this along. Specific comments below:

+1, I didn't know about this but was pleased to hear about it. 

At one point, in 2005, we implemented Open Search in Nutch, see:

http://s.apache.org/il

+1.

Couldn't this be handled via XML Schema and XSD?

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?

I think it should be an interface too...I don't have any in mind off the top of my head but would be great to know
if other folks do.

Cheers,
Chris
