The Fledge project is exclusively focused on the industrial market. From a SWOT (Strength-Weakness-Opportunity-Threat) perspective, this limits the audience of potential committers since consumer, home, retail, gaming etc developers are not a fit. An additional challenge in this market is the lack of open source culture with industrials, equipment manufacturers and industrial system integrators. The Fledge project has the goal of changing this culture. Of the current 46 Git Authors roughly 80% are from the industrial market - exclusively.
Demonstrate evidence of, or a plan for, interoperability, compatibility or extension to other LF Edge Projects. Examples may include demonstrating modularity (ability to swap in components between projects).

When the board asked for its first joint project demo, EVE and Fledge stepped up and produced a model wind turbine and an industrial Flir Infrared camera demonstration. Fledge looks forward to more extensions with Akraino, Open Horizon and Intel SDO integrations in 2020.
Fledge has a unique architecture that enables rapid south and northbound protocols and data mappings to be written (w/o a new micro service). The code can be potentially be written in any language. Currently available languages include C/C++, Go and Java (via dynamic linking) and Python (via shim layers). This list can be extended to other relevant languages as needed. Using Python a relatively junior engineer can be very productive (minutes to hours for data mappings, days new protocols). Most industrials have modest development expertise. This feature is a major source of our community activity and addresses a critical pain point in the industrial market.
A recent request was made to leverage southbound connectivity across LF Edge Projects. Fledge is in several PoCs where Fledge has been used to enable commercial platforms south connections. AWS Greengrass being one of them. We could imagine doing a similar northbound integration with the EdgeX Project if desired.
The Fledge roadmap also includes the integration and testing with systems and subsystems lower in the stack. This is an immediate opportunity for cross project cooperation.
