NIST Released V1.0 Seven Volumes of Big Data Interoperability Framework (September 16, 2015), please click here for Review.

There is a broad agreement among commercial, academic, and government leaders about the remarkable potential of "Big Data" to spark innovation, fuel commerce, and drive progress. Big Data is the term used to describe the deluge of data in our networked, digitized, sensor-laden, information driven world. The availability of vast data resources carries the potential to answer questions previously out of reach. Questions like: How do we reliably detect a potential pandemic early enough to intervene? Can we predict new materials with advanced properties before these materials have ever been synthesized? How can we reverse the current advantage of the attacker over the defender in guarding against cybersecurity threats?

However there is also broad agreement on the ability of Big Data to overwhelm traditional approaches. The rate at which data volumes, speeds, and complexity are growing is outpacing scientific and technological advances in data analytics, management, transport, and more.

Despite the widespread agreement on the opportunities and current limitations of Big Data, a lack of consensus on some important, fundamental questions is confusing potential users and holding back progress. What are the attributes that define Big Data solutions? How is Big Data different from the traditional data environments and related applications that we have encountered thus far? What are the essential characteristics of Big Data environments? How do these environments integrate with currently deployed architectures? What are the central scientific, technological, and standardization challenges that need to be addressed to accelerate the deployment of robust Big Data solutions?

NIST Big Data Public Working Group:
NIST is leading the development of a Big Data Technology Roadmap. This roadmap will define and prioritize requirements for interoperability, portability, reusability, and extensibility for big data analytic techniques and technology infrastructure in order to support secure and effective adoption of Big Data. To help develop the ideas in the Big Data Technology Roadmap, NIST is creating the Public Working Group for Big Data.

Scope: The focus of the NBD-PWG is to form a community of interest from industry, academia, and government, with the goal of developing a consensus definitions, taxonomies, secure reference architectures, and technology roadmap. The aim is to create vendor-neutral, technology and infrastructure agnostic deliverables to enable Big Data stakeholders to pick-and-choose best analytics tools for their processing and visualization requirements on the most suitable computing platforms and clusters while allowing value-added from Big Data service providers and flow of data between the stakeholders in a cohesive and secure manner.


  1. Develop Big Data Definitions
  2. Develop Big Data Taxonomies
  3. Develop Big Data Requirements
  4. Develop Big Data Security and Privacy Requirements
  5. Develop Big Data Security and Privacy Reference Architectures
  6. Develop Big Data Reference Architectures
  7. Develop Big Data Technology Roadmap

Target Date: The goal for completion of INITIAL DRAFTs is Friday, September 27, 2013. Further milestones will be developed once the PWG has initiated its regular meetings.

Participants: The NBD-PWG is open to everyone. We hope to bring together stakeholder communities across industry, academic, and government sectors representing all of those with interests in Big Data techniques, technologies, and applications. The group needs your input to meet its goals so please join us for the kick-off meeting and contribute your ideas and insights.

Meetings: The NBD-PWG will hold weekly subgroup meetings Mondays to Fridays from 1100 - 1300 EDT (unless announce otherwise) and every three weeks for a subgroups joint meeting by teleconference. Please click here for the virtual meeting information.

Questions: General questions to the NBD-WG can be addressed to
