This paper presents a new idea of knowledge element indexing, which is considered a foundation of knowledge integration and knowledge discovery across domain. The type of knowledge element, indexing rule, knowledge element extraction with manual work and software, modification of knowledge element, representation of object of knowledge element, link of knowledge element are tested in this paper. The model of numerical value type of knowledge element tests and verifies the theory and method. Results indicate knowledge indexing based on knowledge element is a method of accessibility.
