United we stand, divided we fall is a well-known saying. We are living in the era of virtual collaborations. Advancement on conceptual and technological level has enhanced the way people communicate. Problem nature has also been changed over the time. Today, e-Collaborations are applied to all domains possible. Extensive data and computing resources are in need and assistance from human experts is also becoming essential. Existing paradigms and technology are used to form Virtual Organization (VO), e.g. DataGrid, XSEDE, Facebook, MySpace, etc, but lack of standards remained a critical issue for last two decades. Our research endeavour focuses on developing a design blueprint for the Virtual Organization building process. The proposed standardization process is a two phase activity. The first phase provides requirement analysis and the second phase presents a Reference Architecture for Virtual Organization (RAVO). This form of standardization is chosen to accommodate both the technological and paradigm shift. For justification of our approach we developed the N2Sky system, a VO for the Computational Intelligence community, as a proof of concept implementation, which caught high attention by the research community.
