Cordra

Unlock the power of your digital information

Cordra provides techniques for long-term and storage-independent management of digital information.

Cordra is a core part of CNRI’s Digital Object Architecture, which offers a foundation for representing and interacting with information in the Internet. Cordra provides techniques for creation of, and access to, digital objects as discrete data structures with unique, resolvable identifiers. Any digital information, such as documents, spreadsheet data, videos and scientific datasets, which we call payloads in this system, can be stored and managed as digital objects. Certain metadata can be derived directly from the payloads; and the user may generate additional metadata. Digital objects, once stored in a Cordra instance, get indexed for subsequent search and retrieval, and are allotted persistent identifiers for subsequent referencing.

The research and development of this software has been funded in part by the Defense Advanced Research Projects Agency (DARPA), the Advanced Distributed Learning (ADL) Initiative of the Department of Defense, the National Science Foundation (NSF), the Alfred P. Sloan Foundation, and the National Institute of Standards and Technology (NIST).
