Abstract: With standardization and normalization process of financial reports,large numbers of enterprises are introducing extensible business report language(XI3RL) to disclose and manage their financial data. Because of complexity and domain specific feature of XI3RI，it lacks semantic description for data analysis,leading to the situation that many existing tools capable of multidimensional data analysis cannot understand and deal with XI3RL files. Based on the analysis on XBRL structure, the paper applied Common Warehouse Metamodel(CWM) , which is platform and domain independent, to build a generic multidimensional analysis model from business reports in X13RI_ format. Transforming rules are separated from implementation and hence making the model more generic and open.

Key words: Multidimensional model, Extensible business reporting language, Common warehouse metamodel
