In order to develop semantic structure of clinical pathway (CP) core metadata system., we compared Chinese Standard CPs with advanced CPs in other countries, and found the deficiencies of current Chinese CPs. Then we developed semantic structure of clinical pathway core metadata system based on the Electronic Health Record (EHR) Architecture and Data Standard (Chinese EHR Standard). The results show that China's current standard CPs are ambiguous in classification and structure and simple in properties. We developed semantic framework structure and semantic property structure, and added datagroups under three documents of "main care activities", "main orders", and "main nursing activities" in developing semantic framework structure. We designed four types of metadata including "decision metadata","value metadata","condition metadata", and "reference metadata". We developed semantic framework structure and semantic property structure of CP core metadata system and we believe the building block structure of CPs facilitates computer and Web processing.
