Research And Realization Of Educational Resource Management Grid

With the development of remote education, the educational resources on Internet increases greatly. It provides more educational service function, but also brings new challenge for education resource management. Lacking of the standard brings about a mass of distributed, complicated and heterogeneous educational resources on internet with the development. This resources only can be used in its' own system and can't be shared. The systems also can't realize mutual operation. So this status quo leads to a large number of repeat resource manufactures, low utility and brings much waste. It has been an obstacle for the developing of remote education.To solve problems exist in education resources development on internet, the author consults and analyses a large number of relevant materials. Grid technology was fixed on after investment and study。The thesis proposes education resource management grid to integrate resources in different educational organization dynamically, and the educational resource was demanded to compliant SCORM standard. SCORM put emphasis on content sharable and reuse, while Grid put emphasis on resource sharing in distribute environment. The combination provides flexibility and uniform resource interface for higher level learning management. And the educational resource can be shared or reused in a wider ranger avoiding a large number of repeat resource manufactures.This thesis addresses the education resource management in detail and analyzes the relevant models and key technology aiming at resource of educational systems dynamic sharing. It makes an analysis of key technology and gives the method to resolve it. This resource management model is more flexible comparing traditional ways and can realize virtual organization resource sharing in a wider range shielding heterogeneous system architectures.For the system experiment implementation, GT4 was used as the grid platform for registration, publishing, and deployment of the learning objects. The prototype also uses J2EE and web service technology etc. The experimental results show that different learning system can add in a VO (virtual organization) dynamically and learning resource supports binding to reach heterogeneous learning management systems dynamic integration.
