Unified Information Modeling for Achieving High-Performance Information Sharing in the Information Grid

In this paper, an unified information description model (“UIDM” for short) is proposed to model information from multiple sources in the Information Grid uniformly. In the UIDM: 1) An unified information description language derived from the ODLI3 is presented to describe information uniformly to resolve the information heterogeneity; 2) A set of diagrammatized information modeling symbols are defined to model the information diagrammatically to illustrate the semantic relationships between information classes; 3) An information capability model is advanced to model the capability of information from different information sources, based on which the high-performance global views for information sharing are to be constructed.
