I have also noticed that many of the experiment properties are 
annotation-like and that it would be better to simply use annotations 
instead. Unfortunately, it's too late to include this in the BASE 3 
release, so I guess it will have to wait for BASE 3.1. Making the 
experiment annotable is fairly easy. The existing information must stay 
as it is.

Regarding default annotation types, I think it is best to not include 
any in a standard installation. Ontologies tend to change every now and 
then, so it's better to let administrators handle that.


The demand for IT networking professionals continues to grow, and the
demand for specialized networking skills is growing even more rapidly.
