Patricia,
I haven't seen either a BR100 or BFA for OTM to date. You'll find that most of the people currently working on OTM actually began working with the product when it was called GC3 (prior to Oracle's acquisition of G-Log) - so most of the Oracle standard processes, documentation and methodology aren't available for the application yet. G-Log officially became part of Oracle in November of 2005 - so it will take a while before the assimilation is complete
Hope this helps!
