The highest and lowest structure compatability rates are related to "contextualize" and "identify" user tasks with 99.07 and 78.3 wighted scores respectively. Also, the mean content compatability of IranMARC name authority records with FRAD model is 25.02. The highest and lowest content compatability are pertained to "justify" and "find" user tasks with 37.82 and 18.26 weighted scores respectively. Conclusion: IranMARC has the maximum structure and content compatability with FRAD model in "contextualize" and "justify" user tasks.
