Maturity Levels

LF Edge projects have an associated maturity level, as voted per the approved Project Lifecycle Document (PLD) process. The maturity level is a signal as to where the project is in its lifecycle, dependent upon number of commits, use in POCs, community participation, interoperability/compatibility with other LF Edge projects, publicly documented release cycles, and more. Details on LF Edge project stages are available here.

Stage 1: At Large

At Large projects are projects which the TAC believes are, or have the potential to be, important to the ecosystem of Top-Level Projects or the Edge ecosystem as a whole. They may be early-stage projects just getting started, or they may be long-established projects with minimal resource needs. The At Large stage provides a beneficial, neutral home for these projects in order to foster collaborative development and provide a path to deeper alignment with other Foundation projects via the graduation process.

Stage 2: Growth Stage

The Growth Stage is for projects that are interested in reaching the Impact Stage, and have identified a growth plan for doing so. Growth Stage projects will receive mentorship from the TAC and are expected to actively develop their community of contributors, governance, project documentation, and other variables identified in the growth plan that factor in to broad success and adoption.

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.

Stage 4: Emeritus Stage

Emeritus projects are projects which the maintainers feel have reached or are nearing end-of-life. Emeritus projects have contributed to the ecosystem, but are not necessarily recommended for modern development as there may be more actively maintained choices. The Foundation appreciates the contributions of these projects and their communities, and the role they have played in moving the ecosystem forward.
