the Subversion revision control system, there has not been any substantial update to the codebase since 2003. Apache Tapestry has a design and philosophy similar to that of WebObjects. Tapestry is frequently combined with Apache Cayenne, a persistence framework inspired by EOF. GETobjects is another framework with an API similar to WebObjects 5.x that is related to SOPE.
