1. Data commons co-locate large biomedical datasets with cloud computing infrastructure and analysis tools to create shared resources for the research community.
2. The NCI Genomic Data Commons is an example of a data commons that makes over 2.5 petabytes of cancer genomics data available through web portals, APIs, and harmonized analysis pipelines.
3. The Gen3 platform is an open source software stack for building data commons that can interoperate through common APIs and data models to support reproducible, collaborative research across projects.

Biomedical Datasets are Analyzed and Shared

3. NCI Genomic Data Commons*
• The GDC makes over 2.5
PB of cancer genomics
data available to the
research community.
• The data is harmonized
by processing with a
common set of
bioinformatics pipelines.
• Each month, the GDC is
used by over 20,000
users and over 2 PB of
data is downloaded.
• The GDC is based upon
an open source
software stack that can
be used to build other
data commons.*See: NCI Genomic Data Commons: Grossman, Robert L., et al. "Toward a shared vision for cancer
genomic data." New England Journal of Medicine 375.12 (2016): 1109-1112.
The GDC consists of: 1) a data exploration & visualization portal (DAVE), 2) a
data submission portal, 3) a data analysis and harmonization system system, 4)
an API so third party can build applications.

8. What is a Data Commons?
Data commons co-locate data with cloud computing infrastructure and
commonly used software services, tools & apps for managing, analyzing and
sharing data to create an interoperable resource for the research community.*

9. Research ethics
committees (RECs) review
the ethical acceptability of
research involving human
participants. Historically,
the principal emphases of
RECs have been to protect
participants from physical
harms and to provide
assurance as to
participants’ interests and
welfare.*
[The Framework] is
guided by, Article 27 of
the 1948 Universal
Declaration of Human
Rights. Article 27
guarantees the rights
of every individual in
the world "to share in
scientific advancement
and its benefits"
(including to freely
engage in responsible
scientific inquiry)…*
Protect patients
The right of
patients to benefit
from research.
*GA4GH Framework for Responsible Sharing of Genomic and Health-Related Data, see goo.gl/CTavQR
Data sharing with protections provides the evidence
so patients can benefit from advances in research.
Data commons balance protecting patient data with open
research that benefits patients:

25. www.occ-data.org
• U.S based 501(c)(3) not-for-profit corporation founded in 2008.
• The OCC manages data commons to support medical and health care
research, including the BloodPAC Data Commons and the BRAIN
Commons.
• The OCC manages data commons and cloud computing infrastructure
to support more general scientific research, including the OCC NOAA
Environmental Data Commons and the Open Science Data Cloud.
• It is international and includes universities, not-for-profits, companies
and government agencies.
26. Sharing Data with Data Commons – the Main Steps
1. Require data sharing. Put data sharing requirements into your
project or consortium agreements.
2. Build a commons. Set up, work with others to set up, or join an
existing data commons, fund it, and develop an operating plan,
governance structure, and a sustainability plan.
3. Populate the commons. Provide resources to your data
generators to get the data into data commons.
4. Interoperate with other commons. Interoperate with other
commons that can accelerate research discoveries.
5. Support commons use. Support the development of third party
apps that can make discoveries over your commons.

30. • It is important to note that with the Gen3 platform, multiple geographically
distributed data commons can interoperate in different ways:
o through data peering
o through a FAIR-based set of APIs for applications
o through scattering queries/analyses and gathering the results
o through a controlled and monitored query/analysis gateway

33. Six Options for Building a Data Commons
1. Add your project data to an existing data commons.
2. Join an existing partnership that serves multiple related diseases based
upon the Gen3 Data Commons platform or other platform designed with
similar goals
3. Build your own data commons and peer with an existing partnership of
data commons developed using the Gen3 Data Commons Platform or
other platform designed with similar goals.
4. Build your own data commons that follow standards for interoperating
data commons, such as the Commons Alliance standards.
5. Build your own data commons that follow standards for research data,
such as the FAIR standards.
6. Build your own data commons with a new architecture and new
standards and get others to adapt your standards.
35. Benefits of Data Commons and Data Sharing
1. The data is available to other researchers for discovery, which moves
the research field faster.
2. Data commons support repeatable, reproducible and open research.
3. Some diseases are dependent upon having a critical mass of data to
provide the required statistical power for the scientific evidence (e.g.
to study combinations of rare mutations in cancer)
4. Data commons can interoperate with each other so that over time
data sharing can benefit from a “network effect”
5. With more data, smaller effects can be studied (e.g. to understand
the effect of environmental factors on disease) and machine learning
techniques that require large data can developed.

41. Abstract
Biomedical data has grown too large for most research groups to host
and analyze the data from large projects themselves. Data commons
provide an alternative by co-locating data, storage and computing
resources with commonly used software services, applications and
tools for analyzing, harmonizing and sharing data to create an
interoperable resource for the research community. We give an
overview of data commons and describe some lessons learned from
the NCI Genomic Data Commons, the BloodPAC Data Commons and
the BRAIN Commons. We also give an overview of how an organization
can set up a commons themselves.
