As part of participating in the Sedona Framework community, consider joining the Sedona Framework discussion group on Google. This group is a great place to ask questions about the open source Sedona software. You can also ask questions here about using the open source software to port Sedona to your own platform.
Any questions regarding integration of Sedona with NiagaraAX™, or any other product offering from Tridium, should instead be asked on the Niagara Central Forums, under the Sedona Framework category. A Niagara Central account is required to participate in these forums. (Create one for free if you don't already have one.)
