This workstream will explore the desired architecture for the DPLA and will make recommendations regarding technology to be used for its development and to build or facilitate building the discovery environment. This track will also examine the state of the art for digitizing books, video, audio, and other types of documents and determining how much it might cost to greatly increase the scope of current digitization efforts.

Big issues: The project may be helpful at the level of standards, interfaces, APIs, and so forth for already and to-be digitized content for public usage. It also may be helpful insofar as we can help to nudge toward better access via current digital means of accessing books, including eBooks.
Beta Sprints provide a sense of how people might use or interact with the DPLA.

Questions for Discussion
Special thanks to Carl Malamud for developing an initial list of discussion questions.
- Who is digitizing at scale and what technologies are they using? Is the technology base similar for books and other media or are there digitization silos?
- Are there technologies in research & development or even pure research that hold promise to bring costs down, volume up, quality up, or longevity up?
- Do we have any idea of the magnitude of information to be digitized? For example, are there hard numbers on books, their location, and the overlap among institutions?
- Are we focusing only on digitization technologies or also on the requirements for long-term preservation of digital assets (e.g. migration, emulation and associated costs, some national libraries addressed both in their initial planning and cost projections)?
- Assuming DPLA will be a distributed system, what is the optimal information architecture to ensure interoperability, in the US and globally, with other national libraries?
- What quality standards should we hold mass-digitization efforts to? When is "good enough" good enough?
- What does digitization mean for printed text material? Pictures of pages, sufficient transcription for search, accurate transcription, transcribed text with semantic annotations? How to distinguish between between them?
- Is the DPLA effort about digitization only, or is it also feasible to discuss the collection, preservation, and dissemination of born-digital content?
- What standards will be necessary for efficient creation of, sharing of, interoperability of, and preservation of the content within DPLA?
- What elements might be missing in the standards landscape that would facilitate the DPLA?
- The need and scope for a work identifier which could limit the duplication that might occur from a distributed digitization effort? Is the International Standard Text Code (ISTC) appropriate for this?
- How will the integrity of the digitized documents be maintained? (via Duane Dunston)
- What mechanisms will be in place for researchers and the public to check to ensure books and scholarly papers are the original documents (i.e. the integrity of the original document hasn't been altered)? (via Duane Dunston)
- What metadata standards will the Library adopt?
- What provisions will there be for interoperability with other collections of digital material?
- How important is the World Wide Web and its stack of technologies to the Library?
- Will the DPLA be a host of content or will it be a federation of other content repositories?
- Will the DPLA contact and work with the Internet Society (ISOC) and how will their experience, structures and methods be leveraged/adopted/adapted? For example, the arms of Internet Research Task Force (IRTF) and Internet Engineering Task Force (IETF) and the process of iterating Request For Comments (RFC) leading from first idea to draft/final specifications (and/or standards) with working prototypes along the way. Have experts at ISOC already solved like technical problems DPLA is likely to encounter? For example, the evolution of the Simple Mail Transfer Protocol (SMTP) and Hypertext Transfer (or Transport) Protocol (HTTP).
- Will the DPLA be inspired by the Open Cloud Initiative (OCI), Open Source Initiative (OSI) and Open Source Definition (OSD)?
- How much attention should the DPLA pay to end user issues such as the possibility of the creation of firmware and apps for public library users and alliances and educational officers in the last-mile area? Does access, in the technical sense, count?
- Should the DPLA establish a close relationship with the International Digital Publishing Forum, the leading organization in the area of e-book standards?
- Might the DPLA actually do well to spin off a separate technical organization serving the needs of both academic and private digital library systems, which could be separate?
