This project is building an Open Archives Initiative (OAI) compliant federated digital library with an emphasis on physics for the National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL). This physics digital library will federate holdings from the physics e-print server arXiv (http://arXiv.org), Physical Review D from the American Physical Society (http://prd.aps.org), and the collected holdings from the Technical Report Interchange (TRI) project (http://egbert.cs.odu.edu/tri/html/). TRI includes reports from the NASA Langley Research Center, Los Alamos National Laboratory, and the Air Force Research Laboratory. Other holdings are being imported from the Arc project (http://arc.cs.odu.edu).To federate collections with varying degrees of richness of metadata elements poses a number of challenging questions, which the investigators are addressing, in the areas of resource discovery, creation and maintenance of harvested metadata, and economic sustainability. Regarding resource discovery:(1) How do we enable users to search across diverse collections within one common interface without losing the ability of searching with richer metadata elements for collections that support them?(2) How do we address the lack of a uniform controlled vocabulary?(3) How do we map the user's view of the domain into the metadata models of the participating archives?Regarding creation and maintenance:(1) What is the most effective way of keeping the metadata between data providers and the federation service consistent almost all the time? Are the current OAI protocols sufficiently developed and robust enough to support the consistency?(2) How do we address the dynamic nature of the collections?The Office of Multidisciplinary Activities in NSF's Directorate for Mathematical and Physical Sciences is providing significant co-funding for this project in recognition of its emphasis on developing collections and services in the area of physics.

该项目正在为国家科学、数学、工程和技术教育数字图书馆（NSDL）建立一个符合开放档案倡议（OAI）的联合数字图书馆，重点是物理学。 该物理数字图书馆将联合物理电子印刷服务器arXiv（http：arXiv.org）、美国物理学会的Physical Review D（http：prd.aps.org）以及技术报告交换（TRI）项目（http：//egbert.cs.odu.edu/tri/html/）收集的馆藏。 TRI包括来自NASA兰利研究中心、洛斯阿拉莫斯国家实验室和空军研究实验室的报告。 从Arc项目（http：//www.example.com）导入其他馆藏。将不同丰富程度的元数据元素集合联合起来，在资源发现、创建和维护收获的元数据以及经济可持续性等领域提出了许多具有挑战性的问题，调查人员正在解决这些问题。arc.cs.odu.edu 关于资源发现：（1）我们如何使用户能够在一个公共界面中搜索不同的集合，而不会失去使用更丰富的元数据元素搜索支持它们的集合的能力？(2)我们如何解决缺乏统一控制词汇的问题？(3)我们如何将用户的域视图映射到参与归档的元数据模型中？关于创建和维护：（1）保持数据提供者和联邦服务之间的元数据几乎始终一致的最有效方法是什么？ 当前的OAI协议是否足够成熟和健壮，足以支持一致性？(2)我们如何处理收藏品的动态性质？国家科学基金会数学和物理科学理事会的多学科活动办公室为该项目提供了大量的共同资金，以表彰其对发展物理学领域的收藏和服务的重视。
