Hi all,

Having just happened across these COCOMO metrics*** on Ohloh for Saxon and XQilla
XSLT/XQuery/XPath products/projects, I thought the list might be interested in the
"bean count" estimates assuming a developer salary of $55000 p.a. to write these projects
from scratch.

*** http://en.wikipedia.org/wiki/COCOMO

For Saxon (and presumably this just the Open Source Non-SA codebase)


50 Person Years $ 2,743,467

And for XQilla


35 Person Years $ 1,899,031

Obviously it's anyone's guess if there's more than zero significant digits in the
$ values let alone 7 digits! Actually I stumbled across the XQilla page first and,
given the friendly URL, took a stab at seeing if Saxon was there too. And it was!

Any comments, people?
