The Jiangmen Underground Neutrino Observatory (JUNO), under construction in southern China, will determine the neutrino mass hierarchy (MH) by observing neutrinos from nuclear reactors at the distance of 53 km. To reach the desired sensitivity (> 3σ) for MH, the radiopurity of the different detector components plays a crucial role. To ensure the purity of the 20 kt liquid scintillator (LS) target of JUNO, the Online Scintillator Internal Radioactivity Investigation System (OSIRIS) will be constructed. It will monitor the radiopurity of the LS during its production and the filling phase of the central detector of JUNO. The OSIRIS will utilize the novel concept of intelligent-PMT i.e. the necessary DAQ electronics will be mounted at the back of the PMT. Each iPMT will then act as an individual self-triggering digitizer. Due to the asynchronous data flow from the iPMT system and of the order of 15 kHz dark count rate per PMT, this chosen approach requires a triggering and physical event building in software level. This talk will report the design, progress and status of the DAQ software for OSIRIS. This work is supported by the DFG Research Unit "JUNO"
