The main objectives of this two-year project are to build a functioning digital library of reusable instructional and learning materials for undergraduate level science and to use the library as a testbed to address several important research issues in the evolution and use of digital libraries. The project represents a collaboration between the COLLEGIS Research Institute (CRI), the Instructional Management System (IMS) Project, the University of North Carolina at Wilmington (UNCW), the ACM SIGGRAPH Education Committee's Digital Library (SECDL), the institutions that comprise the Computer Science Teaching Center (CSTC), and EDUCAUSE. The library content includes diverse undergraduate science-education resources coming initially from the members of the collaboration. The high quality digital resources provided by these groups range from primary source materials, such as datasets and images, to Java applets and visualization tools, to complex simulations and structured curriculum fragments. They also span a wide range of subjects from Earth sciences to pure mathematics. The library is adopting the IMS standards being created to represent instructional and learning materials in a platform-independent, reusable way. Specifically, library content is being described using IMS metadata to provide a testbed for the IMS standards. The IMS metadata is being extended as necessary to cover the diverse material being tagged. The main tasks of the project are to construct an initial version of the library, called XXDL, to incorporate the diverse content of the project partners into the library, to establish the procedures by which the resources are catalogued and reviewed independently, and to grow the library user community. The main tasks of the second year include a broad evaluation of the effectiveness of the XXDL and a more focused investigation of the roles, costs, and benefits of using the standardized IMS metadata for tagging the data. The expectation is that IMS should provide superior indexing because it has been designed expressly to characterize instructional and learning content and because the use of standards should ensure that all content catalogers apply a uniform descriptive schema to diverse learning resources. It is anticipated that XXDL users will benefit by having powerful and predictable tools with which to find appropriate learning and instructional materials. In addition to providing a "stress test" of the IMS metadata, the project should have several additional broad impacts. It directly benefits undergraduate science faculty who use the library to develop improved digital course materials. It also helps faculty to create collaborative communities to share and reuse learning resources. The evaluation of XXDL helps library developers understand how to design more effective digital libraries and online communities that encourage reuse of learning materials and collaboration. The XXDL testbed can be used for future focused investigations of digital library issues.

这个为期两年的项目的主要目标是为本科水平的科学建立一个可重复使用的教学和学习材料的功能数字图书馆，并使用该图书馆作为测试平台来解决数字图书馆发展和使用中的几个重要研究问题。 该项目代表了 COLLEGIS 研究所 (CRI)、教学管理系统 (IMS) 项目、北卡罗来纳大学威尔明顿分校 (UNCW)、ACM SIGGRAPH 教育委员会数字图书馆 (SECDL) 以及由以下机构组成的机构之间的合作：计算机科学教学中心 (CSTC) 和 EDUCAUSE。 图书馆内容包括最初来自合作成员的各种本科科学教育资源。 这些团体提供的高质量数字资源范围广泛，从数据集和图像等主要来源材料，到 Java 小程序和可视化工具，再到复杂的模拟和结构化课程片段。 它们还涵盖从地球科学到纯数学的广泛学科。 该图书馆正在采用正在创建的 IMS 标准，以独立于平台、可重用的方式表示教学和学习材料。 具体来说，正在使用 IMS 元数据描述库内容，以为 IMS 标准提供测试平台。 IMS 元数据正在根据需要进行扩展，以涵盖被标记的各种材料。 该项目的主要任务是构建一个名为 XXDL 的图书馆初始版本，将项目合作伙伴的不同内容纳入图书馆，建立资源编目和独立审查的程序，并发展图书馆用户社区。 第二年的主要任务包括对 XXDL 的有效性进行广泛评估，以及对使用标准化 IMS 元数据标记数据的作用、成本和收益进行更集中的调查。人们期望 IMS 应该提供卓越的索引，因为它的设计是为了明确教学和学习内容的特征，并且标准的使用应该确保所有内容编目员对不同的学习资源应用统一的描述模式。 预计 XXDL 用户将受益于拥有强大且可预测的工具来查找适当的学习和教学材料。除了提供 IMS 元数据的“压力测试”之外，该项目还应具有其他几个广泛的影响。 它直接使本科科学教师受益，他们使用该图书馆开发改进的数字课程材料。 它还帮助教师创建协作社区来共享和重用学习资源。 XXDL 的评估有助于图书馆开发人员了解如何设计更有效的数字图书馆和在线社区，以鼓励学习材料的重用和协作。 XXDL 测试床可用于未来对数字图书馆问题的重点调查。
