Abstract

The CeLeBraTe (Context eLearning with Broadband Technologies) project is developing a system to support a European Learning Network (ELN) of virtual learning environments capable of exchanging digitally stored learning resources. The ELN is built around a Brokerage System that manages exchanges between its members. Unlike other virtual learning environment networks based on a client-server architecture, CeLeBraTe is based on a mixed approach where, although the brokerage system hosts a central metadata repository, each ELN member is also authorized to manage its own local metadata repository. Search requests are both handled centrally and propagated to local repositories.
学习对象及其元数据的联合和代理
CeLeBraTe(宽带技术背景电子学习)项目正在开发一个系统,以支持能够交换数字存储学习资源的虚拟学习环境的欧洲学习网络(ELN)。ELN是围绕经纪系统建立的,该系统管理其成员之间的交易。与其他基于客户机-服务器架构的虚拟学习环境网络不同,CeLeBraTe基于混合方法,其中,尽管经纪系统托管一个中央元数据存储库,但每个ELN成员也被授权管理自己的本地元数据存储库。搜索请求集中处理并传播到本地存储库。
