This is an opportunity to get into the weeds on various implementations of products that are under development in the Genomic Knowledge Standards (GKS) Work Stream. Ideally, we will provide some prerequisite materials on several implementation projects being piloted with GKS. Both implementation project representatives and session participants will have the opportunity to raise concerns, identify needs in both modelling and tooling, and discuss solutions as time permits. This session builds on the You Only Implement Twice session from the 2024 Connect meeting in Ascona, Switzerland. In this new version of the session, we aim to increase the time for focusing on challenges and discussing solutions by providing prerequisite videos or reading material that all participants can review ahead of the session.
