Code4lib 2007, Eric Hatcher, Day 2 Keynote 2007 March 1
Eric started off we a Southern preacher-type monologue which was pretty funny. Eric said his mission at his job is based on the fact that “you can’t use what you can’t find.” Eric discussed Solr Flare. Eric defined the basic idea with facets is to show the entire universe (or some subset) of object divided into subsets based on attributes. Really, when it comes to it, facets are really just basic set theory. The Flare part of Solr Flare is only a small bit of code that runs on top of Solr.
Eric showed of f Delicious Library (An OS X application to keep track of your books). He then exported the content for Delicious library and placed it into Solr. The results were pretty neat. I think this would be a great way to put your personal library on the Web. It may also work well with a LUG library 
. He mentioned he is working at doing this with iTunes data as well.
The URL for Flare is: http://wiki.apache.org.solr.Flare
At this point they still have a lot of work to do to increase scalability. They are still at a “proof on concept” stage, however the future is bright.
