The Research Of Resource Share In Sharable Object Structure Model Using RDF/XML

Co-building and sharing resource is an important research field in distance education (DE). In the view of DE based on Internet nowadays, to construct the learning resources, people must pay more attention to whether the resources are convenient for management, query, cobuilding and sharing.Today, many education departments in our country or abroad give their standards of DE. Most of them are using XML (Extensible Markup Language) for the cobuilding and sharing problems.But XML has some disadvantages of its own. Especially, it cannot describe the semantic information. This disadvantage makes the cooperation of learning resources only can be on syntax, but never on semantic. Lack of such ability blocks the developing of personalized learning and intelligent search in DE.Berners-Lee, the founder of WWW, put forward the concept of Semantic Web in 2001. This conception wants to make some kind of descirption, which can be understood and treated by computers. That means these descriptions must have semantic attributes. The main technique of Semantic Web is based on XML and RDF. Now, RDF is becomming the new hot point for DE research. This technique can resolve the semantic disadvantage ofXML in a certain extent. But the research is on the principium phase. It needs more deeply research yet.This thesis using RDF in the Sharable Content Object Structure Model (SCOSM), ameliorates the model, and makes it have the ability of semantic decribing in a certain extend. In the thesis, XML's disadvantages firstly are analyzed, and a certain menthod is put forward to resolve this problem. After that, certain RDF descriptions of SCOSM are given with some related algorithms. In the end, an application is made using the RDF tools of Jena.
