4:30 – 5:30 Interoperability Among Projects

Interoperability among projects is emphasised by the ability of various open-source projects to work with or use the parts of functionality, features, governance model, community guidelines etc., with one another. Being interoperable solves a shared problem and flushes out the hidden flaws in the system/process when exposed to a more significant user base.

There have been mutual efforts in the past initiated by several OSS projects to work on a shared technical functionality that benefitted the user and developer community of the projects involved. However, many efforts and feats have not surfaced, and we’d like to have an open discussion on this topic with the projects involved at the Summit. There would be a moderator to initiate and guide the conversation, and attendees are welcome to participate and share their thoughts. Please join us @ 16:30 in Alexander Valley I & II on 22nd September.

11:00 – 12:00 Project Sustainability & Resiliency
Every open-source project aims to be sustainable and can be achieved in various ways, like securing grants, expanding and engaging user/developer communities, informed decisions on what tools and practices to adopt, etc. Open-source projects are dynamic and continuously evolving systems. OSS projects can face a crisis from time to time financially and community-wise, like developers abandoning the project, less participation from the community, delayed feedback on issues etc. Being resilient plays a vital role and is a crucial component of the sustainability of projects. It focuses on how you tackle those issues and progress in the face of unfavourable situations.
