Lafcadio is an object-relational mapping library for Ruby.

It currently supports MySQL and PostgreSQL.

Features include:

In development since 2002, Lafcadio is still in active development, but is mature enough to be used in production systems. Most notably, it's used at Rhizome.org, an online arts website that gets more than a million pageviews a month.
