Resolving context differences between heterogeneous systems for global information interoperability is a challenging research issue in information technology. This paper solved the problem by suggesting a new concept of Open Information Platform (OIP) that builds on the two principles of naturalization and alienation. Following these two principles, an SCI methodology has been proposed to require standardization of information, collaborative creation of atomic signs and internalization of standardized information to hide complex standards behind final users. To implement the SCI method, an OIP technical infrastructure is implemented. The short history of information interoperability research signifies that OIP concept is important and is a natural outcome towards the future technology for information exchange and use. © 2013 IEEE.
