Moderate to severe precipitation were causing deviations within 50 miles of Boston airport. Arrivals were being rerouted back over KRANN intersection to fly the ROBUC 1 and the 22 L transition on a trial basis as the weather was moving out and they would be able to pick their way through. A few minutes after the first two airplanes were vectored in deviating around weather I was told to go into a hold for Boston. Approximately 4 planes were given holding instructions over PROVI. After doing one turn in holding I was told to run them radar using descend via to runway 15R which was a different runway than the originally had. The first aircraft was Aircraft X and I told him to turn right direct KRANN and descend via the ROBUC 1 15R transition. He would have not been able to make the turn to PROVI to pick up the arrival because it would have been too tight of a turn. He reads it back but tells me a few seconds later that KRANN is past the transition point and he would like to go direct JOODY. At that time I had a few BOS departures and was vectoring others out of the hold and did not have a chance to pull up the Arrival in the URET. I approved his request to go direct JOODY and descend via. I say him leave [at] 110 before he got to PROVI but assumed that BOS approach had that airspace. It was not till minutes later that the CIC (Controller in Charge) informed me that I had an airspace violation with PVD approach because there is not a crossing altitude at JOODY so he descended too early to stay out of their airspace. Because descend via is still rather new and some runways get used a lot more than others it is still confusing as to which transition and fix to go to after deviations or holding. During deviations or coming out of a hold descend via should be cancelled so that as airplanes go off course and ask to vectored back on there is no confusion over what speed and altitude to maintain from either pilot or controller.
ZBW Controller reports of deviations due to weather and precipitation with traffic inbound to BOS. Controller let aircraft descend early and assumed BOS had the airspace; but ended up violating airspace belonging to Providence Approach.
