[Esip-discovery] Impact of Discovery services

[Mattmann, Chris A (388J)]

Hey Chris,

We just used the default SOLR Response Writers (one of which is RSS, and others being XML, JSON, etc.) on those projects. In some prior projects, I did use Apache Nutch's OpenSearch response writer (circa 2005) and found it to be quite effective:

http://s.apache.org/DfZ

Here's some docs on the SOLR Response Writers:

http://wiki.apache.org/solr/QueryResponseWriter

It would be really useful to write an ESIP Federated Search response writer and maybe contribute it back to the SOLR community so that downstream users of SOLR (us and any other NASA project) could get the ESIP Federated Search protocol for free.

I've created:

https://issues.apache.org/jira/browse/SOLR-2419

to track this.

Cheers,
Chris
