Project: Improving FHIR Analytics Using Apache Spark and Cassandra

Thank you for your feedback @judywawira. I will add another section called “Previous work done” to my proposal citing the work by @prashadi.

Ans yes, enhancing the UI is one of my goals for the project.

@mshubhankar – this will require wireframes in your proposal to show the UI changes you are proposing.

@mshubhankar Proposal is looking good. Please include the suggestions made by @judywawira and @r0bby. We also need to evaluate the possibilities of integrating automatic query builder for the UI which will omit the requirement of writing the plain Spark SQL queries.

Hello everyone,

It makes me very sad to say that I won’t be able to send a proposal for GSoC this year. One of my supervisors didn’t allow me to take up a GSoC project because of the time constraints. I was really excited by the idea of the project and hoped that I would’ve also learnt a lot from it. I’m sorry I won’t be able to continue as a GSoC participant but I wish to keep contributing to the community in future. I would also like to thank you for all your responses throughout !

@mshubhankar Thank you for letting us know about the situation. It’s sad that you couldn’t do GSoC this year. I wish you all the very best with your work.

Hello All,

I was trying the project past few days. But I was busy with my midterm exams. I’ll try to submit a proposal before the deadline. Since I have to do a contribution, I will try my best to do a contribution.

I’m getting following error many times. Any idea on this?

Thank you.

@eunice18 without completing starter tasks before the deadline will lead to ignore your application considering for the GSoC. @r0bby I believe we have no other options.

that’s a bummer @mshubhankar

It is disappointing, but I am hoping to see you around
