Abstract

Abstract: In the CAS system，integrated analysis is implemented on storage metadata and content metadata，and then objects are classified and stored according to their attribute values.To facilitate the users，Inotify is used for real-time monitoring of file system，metadata information of object is extracted automatically.The information is preserved in standard XML documents and MYSQL databases，and various attributes can properly be reflected in the CAS system.Integrated analysis automatically extracts metadata information，which can greatly help users search and manage multimedia data.

Key words: metadata, multimedia, object storage

摘要： 在CAS系统中，提出了将多媒体对象的存储元数据和内容元数据进行整合分析，然后根据属性值的不同将对象归类存储。并且为方便用户使用，使用了Inotify对文件系统进行实时监控，自动提取对象的各项元数据信息。对象的元数据信息使用标准的XML文件和MYSQL数据库分别保存，并且各项属性能在CAS系统中很好地体现出来。整合分析自动提取的元数据信息可以极大地帮助用户提高搜索和管理多媒体数据的效率。
