Overview of nDEX

  • NDEx  users can easily create accounts or sign in using their Google credentials thanks to  the supported open authentication (OAUTH2) method  and mint DOIs for their networks to use in publications or include in other resources for long term access.
  • NDEx, created by members of the same research lab, serves as an Expo for networks—researchers can share networks they have developed and other researchers can search for networks and made them the basis for further incorporation of data or analyses.
  • NDEx, the Network Data Exchange, is an open-source (Data S1, Open Source) software framework that facilitates the sharing of networks of many types and formats, the publication of networks as data, and the use of networks in modular software.
  • NDEx client libraries for this API have been created in the Java, Python, and R languages to facilitate easy use by scientists, though NDEx can be accessed via any language capable of Internet communications (Data S1, REST API).
  • NDEx therefore differs in approach from WikiPathways (Pico et al., 2008), a pioneering collaborative platform for the curation of biological pathways, where all documents are publically edited and use a single format.
  • NDEx promotes the development of new network analysis algorithms and applications by expanding access to networks as inputs, by facilitating immediate sharing of network results and by providing a path to publication.
  • NDEx is distinct from other online network repositories which include KEGG and Pathway Commons in that users manage their own networks rather than the networks being managed by the organization that maintains the resource.
  • NDEx provides accession identifiers for every network, assigning a universal unique identifier (UUID) that distinguishes it from all other networks across all servers.
  • NDEx lets you specify Licenses and Request DOIs for your networks to include in grant proposals or publications thus enabling papers to link directly to the data.
  • NDEx 2.0 is a significant step in the evolution of the NDEx data commons, supporting its mission to foster network-centered communities of scientists.

    The NDEx Project provides an open-source framework where scientists and organizations can store, share, manipulate, and publish biological network knowledge.One of the goals of the project is to create a home for models that are currently available only as figures, tables, or supplementary information, such as networks produced via systematic mining and integration of large-scale molecular data.The NDEx project does not compete with existing pathway and interaction databases, such as Pathway Commons, KEGG, or Reactome; instead, NDEx provides a novel, common distribution channel for these efforts, preserving their identity and attribution rather than subsuming them.


    >> Learn More…Individual users and organizations can make networks public, findable and accessible in NDEx; each public network has its unique, stable URL and can always be downloaded either manually or programmatically, via our REST API.NDEx includes features to support data distribution and access according to FAIR principles and is registered on FAIRsharing.org .Readers can now go from static figures to interactive, actionable data objects in just a few clicks!Vice versa, networks linking out to the papers they support provide you with new opportunities for discovery and citation.NDEx is recommended by Scientific Data, Springer Nature and the PLOS family of journals.


    A private NDEx can also be deployed on local servers or on a scientist’s desktop for applications that store very large networks or perform frequent, large transactions.An NDEx server can be installed behind a firewall to handle cases where strong security is required, enabling storage of proprietary networks developed for the health sciences industry or those that incorporate patient information subject to privacy standards (e.g., HIPAA, the Health Insurance Portability and Accountability Act).Applications can simultaneously access both public and private NDEx servers, or users can coordinate private NDEx instances with a public server using NDEx Sync (Data S1, NDEx Sync), a command line utility that can copy and update selected networks between servers.Finally, users can download and deploy the NDEx server software for private uses that would be impractical or unsupported on the shared public server.

    Why the N-DEx System?

    The N-DEx system complements other well-known FBI systems, such as the National Crime Information Center (NCIC), Interstate Identification Index (III), and Next Generation Identification (NGI) that provide critical information to the criminal justice community.The information that would not be contained in those systems, i.e., incident and case reports, full Department of Justice (DOJ) case files, and corrections data, is available in N-DEx.And the N-DEx system has been endorsed by a number of major criminal justice associations, including the following: International Chiefs of Police, National Sheriffs’ Association, Association of State Correctional Administrators, National Institute of Corrections, American Probation and Parole Administrators, Corrections Technology Association, Major Cities Chiefs Association, and Major County Sheriffs’ Association.

    Why NDEx?

    What can I do with NDEx ? Why should I care to use it? These are very common questions that scientists might ask when presented a new tool they have never used before…
