The original CORBA-based AT-SPI (git module at-spi) is being replaced by the DBus port, which is hosted on git.gnome.org under at-spi2-core, at-spi2-atk, and pyatspi2.  there is currently a bugzila product called at-spi, but it is no longer in synch with the AT-SPI2 git repositories.

I am not sure how best to handle this; perhaps an AT-SPI2 product could be created and the product description for the original AT-SPI could be updated to indicate that it refers to the deprecated CORBA-based AT-SPI.  The components for AT-SPI are applicable to AT-SPI2 with the exception of the Java-related components; I am not sure why those are included in the AT-SPI product, since java-atk-wrapper is its own module and is simply an ATK implementation that does not touch AT-SPI.
