基于内容的对象存储技术的研究

由于目前的内容寻址存储系统在应用时存在很大的问题,提出基于标准HTTP协议开发CAS存储接口,将文件操作映射为URI资源的标签语义,实现基于Web的文件存取和操作;并借助Web服务器和数据库建立功能强大的CAS客户端,基于元数据模型并结合数据库对文件对象进行描述,通过Web界面进行文件对象浏览和搜索,构建具有强大内容导航和搜索能力的对象存储系统.

Research of Storage Technology Based on Object and Content

Since there are a lot of problems when content addressable storage(CAS)systems are integrated with the application,the design and implement of'a new kind of CAS storage system are proposed in the paper.CAS storage interface based on HTTP,which can turn the operation of documents into the tag semantic operation of URI resources,is able to achieve Web-based admission and operation for documents.With the help of Web server and database,a powerful CAS client can be established.The object of documents are described by the metadata model and database,so CAS client can provide Web interface to navigate and search for documents,and an object-based storage system with powerful capabilities for content navigation and search can be constructed.
