Apache Jackrabbit 2.9.1 发布，JSR-170 内容管理
3月21日 深圳 OSC 源创会开始报名罗，送华为海思开发板Apache Jackrabbit 2.9.1 发布，Apache Jackrabbit 是由 Apache Foundation 提供的 JSR-170 的开放源码实现..
随着内容管理应用程序的日益普及，对用于内容仓库的普通、标准化 API 的需求已凸现出来。Content Repository for
Java Technology API (JSR-170) 的目标就是提供这样一个接口。JSR-170
的一个主要优点是，它不绑定到任何特定的底层架构。例如，JSR-170 实现的后端数据存储可以是文件系统、WebDAV 仓库、支持 XML
的系统，甚至还可以是 SQL 数据库。此外，JSR-170 的导出和导入功能允许一个集成器在内容后端与 JCR 实现之间无缝地切换。
