The concept of collective intelligence is contributing significantly to knowledge creation on the Web. While current knowledge creation activities tend to be founded on the approach of assembling content such as texts, images and videos, we propose here the service-oriented approach. We use the term service grid to refer to a framework of collective intelligence based on Web services. This chapter provides an institutional design mainly for non-profit service grids that are open to the public. In particular, we deepen the discussion of 1) intellectual property rights, 2) application systems, and 3) federated operations from the perspective of the following stakeholders: service providers, service users and service grid operators respectively. The Language Grid has been operating, based on the proposed institutional framework, since December 2007.
