RQ1 = I would like to have my references classified into three databases (research, teaching, home). RQ2 = I would like to capture references from the digital bibliographic databases to which I have access. RQ3 = I would like to have interoperability with my word processor and to have a copy of my reference databases in my PDA.

GESSI Software Engineering Research Group – www.lsi.upc.edu/~gessi/ Current Work We are improving the usability of the formal definition of requirements. We are improving the reusability of metrics in quality models, by developing a general metrics manager for QM. We are filling QM and EV of data  E-learning Tools  Anti-virus Tools  Web Editors
