Stage 3: Impact Stage


The Impact Stage is for projects that have reached their growth goals and are now on a self-sustaining cycle of development, maintenance, and long-term support. Impact Stage projects are widely used in production environments and have large, well-established project communities with a number of contributors from at least two organizations.


  1. Projects that have publicly documented release cycles and plans for LTS.
  2. Projects that have themselves become platforms for other projects.
  3. Projects that are able to attract a healthy number of committers on the basis of its production usefulness (not simply 'developer popularity').
  4. Projects that have several, publicly known, end-user deployments.


Impact Stage projects are expected to participate actively in TAC proceedings, and as such have a binding vote on TAC matters requiring a formal vote, such as the election of a TAC Chair. They receive ongoing financial and marketing support from the Foundation, and are expected to cross promote the foundation along with their activities.

Acceptance Criteria

To graduate from At Large or Growth status, or for a new project to join as an Impact project, a project must meet the Growth stage plus Impact stage criteria:

Stage 2: Growth requirements:

Stage 3: Impact requirements:

Compliance with Requirements

Growth plan

The Fledge project and community plans to create a strong ecosystem around Fledge to attract more users and stimulate community growth by:

The Fledge community has been growing steadily over the years incorporating a diverse set on contributors from various organizations.

  • Recently the Fledge TSC was expanded its voting members to incorporate a diverse representation of organizations.
  • Growing attendance from a variety of users and contributors.
  • Demonstrations of new features.

The Fledge community has identified 4 additional organizations focused on Industrial IIoT standards and systems.  We intend to grow the Fledge community  by engaging all 4 in PoCs, edge strategies and edge contributions.  The four organizations are LF Energy, OSDU, CESMII and the Eclipse Foundation.  

  • LF Energy: is an open source foundation that focuses on power systems hosted within the Linux Foundation. 
  • OSDU (Open Subsurface Data Universe): The OSDU Forum is developing an open source, standards based, technology agnostic data platform. Primarily focuses on oil and gas and renewables.
  • CESMIIRadically accelerate the development and adoption of advanced sensors, controls, platforms, and models, to enable Smart Manufacturing (SM) to become the driving sustainable engine that delivers real-time business improvements in U.S. manufacturing.
  • Eclipse Foundation: The Eclipse Foundation provides our global community of individuals and organizations with a mature, scalable, and business-friendly environment for open source software collaboration and innovation.

Substantial ongoing commits and contributions
Community participation meets growth plan goals

Two main industrial communities in energy verticals have been the main focus but not limited to:

FledgePOWER is a multi-protocol translation gateway for power systems based on the industrial IoT LF Edge project. This cross foundation collaboration between LF Edge and LF Energy ensures strong cooperative governance and technical alignment between the two communities. FledgePOWER aims to build and grow a community of end-users, developers, utilities, and other players to collaborate to solve current and future challenges in the energy space. Further information can be found on:


OSDU has selected Fledge and EVE as the edge stack architecture for OSDU EdgeMeeting OSDU Edge requirements with LF Edge projects mitigating lock-in through vendor-neutral governance and interoperable solutions. 

The architecture was successfully demoed to OSDU members in October, 2021.

Stage 3: Impact

Governing body of at least 5, no more 1/3 from same employer

The Technical Steering Committee (TSC) has expanded its voting members to 6 as follows:

  • Mark Riddoch - Dianomic - Chair
  • Tom Arthur - Dianomic
  • Daniel Lazaro - OSIsoft now part of AVEVA
  • Benoit Jeanson - RTE
  • Robert Raesemann - Raesemann Enterprises
  • Mike Styer - Google
Documented governance, decision-making, release processes

Fledge is an independent open-source project and not controlled by any single company. To emphasize this Fledge is governed under the Linux Foundation Edge and has graduated through the different Project Stages: Definitions and Expectations. Fledge is currently a Stage 2 project under this framework. For more information go to the Governance section.

The following documented processes are in place:

Healthy number of committers from at least two orgs
Evidence of interoperability, compatibility with other LF Edge projects

The latest Fledge collaboration includes:

More information on past and ongoing collaboration can be found here: Cross-LF Edge Collaboration and here Fledge Roadmap 2020/2021.

Adopt LF Code of conductThe Fledge community adheres to the LF Code of Conduct as described here: Code of Conduct
Explicitly define a project governance and committer process

The Fledge community has defined and documented the following Repository Approval Policy as well as the committer process here: and project Governance.

Public list of project adopters

The Fledge Community welcomes contributions of all types; documentation, code changes, new plugins, scripts, just simply reports of the way you use Fledge or suggestions of features you would like to see within Fledge. A public list of project adopters can be found here.
