校园网格资源描述与发现

摘要

Construction of Campus Grid is an effective way to solve the islands issue of campus network resources.The campus grid resources description and discovery mechanism is discussed,and a set of categories describing RDF plus vocabulary resources is proposed.Firstly, it is given the campus grid resource description vocabulary which is based on a resource classification proposed registration model,and then provided a query model based on triples through the RDF triple model described in the analysis.Finally, the resources description,registration,and found is realized using a Campus Grid resource sharing prototype system.The exoeriments show that the described method is feasible and effective_%构建校园网格是解决校园网中资源孤岛问题的有效途径。针对校园网格中资源的描述和发现机制进行研究，提出了IKDF＋词汇集分类描述资源的方法。首先给出校园网格资源描述词汇集，基于该词汇集提出一种资源分类注册模型．然后通过对RDF三元组描述模式的分析，给出基于三元组的查询模型；最后，通过校园网格资源共享原型系统实现了资湄的描述、注册以及发现，实验表明该描述方法可行有效。
