Sharing of Defense Research, Development, Testing, and Evaluation (RDT&E) Data Distribution using Distributed Ledger Technologies



OBJECTIVE: To develop a capability for efficiently and verifiably sharing documents and scientific data sets using distributed ledger (blockchain) technologies. Demonstrate how such capability can be integrated with repositories implemented using conventional technologies such as XML databases. 

DESCRIPTION: The ability to effectively share documents and scientific data sets is critical to promoting collaborations among members of the defense RDT&E community and developing new capabilities to support warfighters. The RDT&E community includes Department of Defense (DOD) research laboratories and their industry and academic partners. The documents produced by the community, such as technical reports, project records, and journey articles, are in a variety of structured (e.g. XML), semi-structured (e.g. PDF) and non-structured (e.g. Text) formats. While Defense Technical Information Center (DTIC) serves the central repository of RDT&E information, relevant documents and data are often published in other repositories as well. For example, scientific data sets are often accessible from repositories maintained by research laboratories and researchers. There are also cases when different versions of the same document exist on multiple websites. For example, scientific papers resulted from DOD-funded research are often available from the journey publisher’s websites. DTIC is looking to leverage distributed ledger technologies to compliment the services and repositories it has developed over the years to facilitate the sharing RDT&E documents and data sets. In particular, the technology should 1) Enable quick discovery of new or updated research information through publication of information on the blockchain; 2) Allow easy identification of authoritative source for any information; 3) Ensure integrity of document and data through validation mechanisms; 4) Support document delivery verification through notification to document owners every time a document is accessed. 

PHASE I: Design and demonstrate efficient and verifiable documents and scientific data sharing solution using open source blockchain platforms. The design should address the nature of the proposed blockchain solutions, e.g. a permissioned blockchain vs an open blockchain. The design should also consider existing metadata standards for scientific data and documents and articulate how these standards will be used. Finally, the solution should provide a roadmap for adopting the capabilities in the RDT&E community, eventually leading to an RDT&E information sharing ecosystem. 

PHASE II: Develop a prototype that implements the Phase I design. Demonstrate the capability using a set of documents and scientific data, to be provided by DTIC. 

PHASE III: The resulting system will enable increased information sharing which has both military and commercial applicability.
