As promised, around November 29th we would publish the reference implementation of the questionnaire platform, as well as some guidelines for the team support and scalability issues. These can be found on Git, under https://github.com/dslmeinte/LWC20u14.
The file README.md that can be found there explains the design of the reference implementation, while the file scalability and teamwork.md gives suggestions and requirements (mainly for model size scalability) on how to deal with the focus assignment.
If you have any questions regarding this, please post them on the Google Group for the Language Workbench Challenge.
Meinte and Angelo will maintain the reference implementation and the focus assignment document – major changes will be largely avoided. If that is not possible, it will be announced here. Cosmetics and minors will appear on Git without further announcement.
Good luck with the assignment – and we hope to see you in Cambridge in a few months time!
