The Lingua Libre v3.0 enhancement and migration project aims to upgrade and migrate the Lingua Libre platform to improve scalability, performance, and user experience. The current backend, utilizing wikibase and blazegraph, presents limitations in scalability and query speed. By transitioning to a Python Django backend and VueJS frontend, the project intends to address these shortcomings, providing a more efficient and elegant service for recording vocabulary from diverse languages. These enhancements will contribute to the enrichment of Wikimedia projects with a broader range of audio-word content.

How it Benefits Wikimedia Projects:

  • Improved scalability and performance will enable the recording of a larger volume of vocabulary, enriching Wikimedia projects with diverse audio-word content.
  • Enhanced user experience will attract more contributors, fostering increased participation and a more comprehensive representation of languages within Wikimedia projects.

Communication Plan:
I plan to maintain open and transparent communication throughout the project. Weekly progress updates will be shared with mentors and the community through email and weekly meetings. Any challenges or roadblocks will be promptly communicated to seek guidance.

Source Code Repository:
The source code will be regularly pushed to a dedicated Gerrit or GitHub or GitLab repository under my account. This will facilitate version control, collaboration, and transparency. Each commit will be accompanied by meaningful commit messages, and major updates will be communicated to mentors and the community.

Seeking Help:
When facing challenges, I will utilize community channels, including mailing lists and forums, to seek help. Additionally, I will actively participate in the weekly meetings with mentors to discuss progress and address any issues. Prompt and clear communication will be maintained to ensure a collaborative and supportive development environment.

This detailed plan outlines the project's goals, benefits, mentorship structure, and a comprehensive timeline for task completion. It reflects a thoughtful approach to contributing to the InlineComments in wikimedia extension during the Google Summer of Code program.

    • This Cypress test case is designed to ensure the functionality of sending a WhatsApp message via the Infobip API. The test involves making a POST request to the Infobip API endpoint with a predefined payload containing message details. After sending the request, the test verifies that the response status code is 200 and checks for expected properties in the response body, such as the presence of messages and their status. The test aims to validate the reliability and correctness of the WhatsApp message sending feature integrated with the Infobip API.
    • This task involves creating a compelling blog post about my reflections about the Outreachy-WhatsApp project. The goal is to share our findings, and propose areas for further exploration.
