This post describes in detail about what I've been working on in the past few days. In my previous blog posts and weekly check-ins, I have written about how i've been contributing to the project. This week saw good improvement. As per my schedule, I'm a bit ahead. I've already implemented label feature for JSONSource that was successfully merged and closed. I was working on solving the issue #48. After that I was working on implementing the label feature for CSVSource as well. I have successfully given a PR and I'm hoping that it gets reviewed and merged by this week. I have also added test cases for this feature. Looking forward to wrap up with this soon so that i can start working on the next phase of my project!
