[OT, slightly] Some interesting metrics on Lucene
http://www.ohloh.net/projects/3564 has some interesting metrics on
Lucene (and Solr and Nutch). Most interesting is that they estimate
it is 34 person years to develop at a cost of approximately $1.8
million dollars (using a salary of $55k)
One thing they do not do in their analysis is look at the help that
people give to the community. There are many people in the community
who contribute a whole lot of time answering questions, etc. who
never submit a single patch. They also don't properly credit the
people who created the original patch, merely giving credit to the
committer who applied it.
At any rate, I thought it was interesting.
Cheers,
Grant

Yep, I didn't really think the money was all that accurate, just
thought it was interesting that someone was trying to quantify it.
Like I said it also severely sells short the contributions of the
community, putting all credit into the committers (for all projects)
which is far from accurate.

before you get too excited, it estimates that Apache Labs (which is a
sandbox where people try things out) is worth $2.5m

FWIW.. I think the brand value of 'lucene' is worth at least 5-10x (if
not more) what ohloh thinks it is.
not to mention the amount of unseen development time corporates have
done around lucene, and the amount of revenue which depends on lucene
working correctly.
