We developed a set of web applications called SQS(Shared Questionnaire System) based on XML technologies for supporting wide variety of social inquiry administrators such as community managers, governors and researchers. The core applications of SQS are distributed OMR(Optical Mark Recognition) systems developed upon XForms so that they have open processing model and open data formats. The integrated OMR systems enables the users in different communities to share informations about how to create hypothesis and how to design questionnaire. We experimentally applied SQS to a survey of public policy issues in an elementary school community in Tokyo, Japan. The use of SQS shows possibility of decentralised and autonomous community management with small cost.
