DPLA已经不是一个传统的图书馆,不是单单把物理资源数字化,事实上它不做这个东西,是参加的成员自动贡献给DPLA,而贡献的方式是通过OAI-PMH协议被DPLA收获harvest。简单来讲,DPLA就和Primo类似是一个发现平台,它是一个OAI-PMH service provider,而各个成员本地的数据库是OAI-PMH data provider,所以加入的成员越来越多,被收获共享东西会越来越多。加入的成员成为DPLA的一个service Hub数字服务港。

DPLA是一个完全虚拟的图书馆。没有任何建筑和实体机构。OAI-PMH就是Open Archives Initiative Protocol for Metadata Harvesting。简单讲两个数字库之间要共享元数据必须遵守的一个数据通讯协议。元数据则遵循Dublin Core标准。


The Digital Public Library of America (DPLA) is a US project aimed at providing public access to digital holdings in order to create a large-scale public digital library. It officially launched on April 18, 2013, after 2.5 years of development.[1]

The DPLA is a discovery tool, or union catalog, for public domain and openly licensed content held by the United States' archives, libraries, museums, and other cultural heritage institutions.[1] It was started by Harvard University's Berkman Center for Internet & Society in 2010, with financial support from the Alfred P. Sloan Foundation,[2]and has subsequently received funding from several foundations and government agencies, including the US National Endowment for the Humanities, and the Bill & Melinda Gates Foundation.[3] It "aims to unify such disparate sources as the Library of Congress, the Internet Archive, various academic collections, and presumably any other collection that would be meaningful to include. ... They have yet to ... decide such issues as how near to the present their catalog will come. There is an ongoing dispute regarding so-called 'orphan works' and other questions of copyright."[4][needs update] John Palfrey, co-director of the Berkman Center, stated in 2011: "We aspire to establish a system whereby all Americans can gain access to information and knowledge in digital formats in a manner that is 'free to all.' It is by no means a plan to replace libraries, but rather to create a common resource for libraries and patrons of all types.”[5]

The DPLA links service hubs, including twelve major state and regional digital libraries or library collaborations, as well as sixteen content hubs that maintain a one-to-one relationship with DPLA.[6][7]
