During the last weeks of December, IT experts of DLR installed the first version of the Information System prototype at the Southern Institute of Water Resources research in HCMC, as well as at Can Tho University in the Mekong Delta. The first test intallations were accompanied by hands on trainings. Purpose of Prototype installation was to firstly promote data sharing and technology transfer, analyse the challenges in Vietnam, and yield insights for further IT development. The prototype will be extended to a fully functional Information System within Phase B of the WISDOM project, which hopefully will start in fall 2010. Challenges to be overcome in Vietnam include: improvement of hardware infrastructure, improvement of local technical capacity, and network security to protect the system from viruses and other attacks.
