Resarch on metedata describe model of writing process for primary grades based on RDF

Primary grades students' thoughts are usually fragmented and their organizational skills of language are poor, so they often can't express and organize their thoughts clearly and logically when they write compositions. Therefore, it is necessary to develop a writing guidance app with information technology which is suitable for primary grades students. The key to writing guidance is to give a reasonable writing process, and then to help students follow the steps of writing process to build their own essay outlines. Although the framework of compositions has not fixed regular, the types of compositions of primary grades students are often specific, so the guideline for writing is often traceable. In this paper, a set of generic writing process models are built by the analysis of a large number of excellent travel notes as an example, then the metadata description model of its step node is established based on the perspective of app development. Finally. it is implemented as the RDF model by using JENA framework so that it can present a technical support for the development of primary grades writing guidance app.
