About MEF LSO Developer Community

The MEF LSO Developer Community enables software developers - typically from service provider IT departments, technology vendor R&D groups and students and post-graduates from academia - to ask questions, respond to questions, and contribute tools and other forms of code for inclusion in the LSO SDKs. The community allows to interact with other members including industry professionals from MEF member companies whose primary purpose is to work together to develop the standard and related SDKs. It is the place to share the knowledge, discuss the current work and propose new features for the next releases.

LSO SDK Communities

LSO SDK for each LSO Reference Point is a collection of the APIs and associated development tools for that LSO Reference Point. LSO SDK repositories are publicly available on GitHub. Additionally there are extended SDK versions developed and are available for MEF Members only. They will contain software tools like adapters, emulators, etc. More LSO SDK details could be found on dedicated wiki pages and the source code is hosted on GitHub (links provided in the section on the right).

Developer community is built around every LSO SDK, and the main goal there is to boost adoption of MEF data models and APIs as defined for various LSO Reference Points in LSO Reference Architecture (MEF 55). The LSO SDK Communities are built with use of the GitHub teams and the team discussions should be used as a communication channel. You could post a new discussion to ask questions and provide comments or join the current discussion.

Currently there are following LSO SDK Communities available:
