DPLA Hub Model – Content and Service Hubs
The DPLA hubs model is establishing a national network out of the over forty state/regional digital libraries and myriad large digital libraries in the US, bringing together digitized and born-digital content from across the country into a single access point for end users, and an open platform for developers. The model supports or establishes local collaborations, professional networks, metadata globalization, and long-term sustainability. It ensures that even the smallest institutions have an on-ramp to participation in DPLA. DPLA content hubs are large libraries, museums, archives, or other digital repositories that maintain a one-to-one relationship with the DPLA. Content hubs, as a general rule, provide more than 200,000 unique metadata records that resolve to digital objects (online texts, photographs, manuscript material, art work, etc.) to the DPLA, and commit to maintaining and enhancing those records as needed. DPLA service hubs are state, regional, or other collaborations that host, aggregate, or otherwise bring together digital objects from libraries, archives, museums, and other cultural heritage institutions. State and regional hubs agree to collect content that describes their local history, but also content about the US broadly and, when available, international topics. Each service hub offers its partners services that range from professional development, digitization, metadata creation or enhancement, to hosting or metadata aggregation. They may also provide community outreach programs to increase users’ awareness of digital content of local relevance. Service hubs provide DPLA with their partners’ unique metadata records that resolve to digital objects (online texts, photographs, manuscript material, art work, etc.) through a single data feed, such as OAI-PMH. They serve as the point of contact for the maintenance and enhancement of metadata records. This will be added to the tools section of Research Resources Subject Tracer™ Information Blog.
