Backend development

The website is built using a PHP/Java backend and a PHP/javascript frontend.

An overview:

• Backend: The high-level architecture of the website, including the controllers for different parts of the website (REST API, html, ...) and connections to the database.
• Helper functions: Mostly written in Java, these functions build search indexes, compute dataset characteristics, generate tasks and evaluate the results of certain tasks.
• URL Mapping A guide to the basics how a URL maps to internal files.
• Frontend: Architecture and libraries involved in generating the frontend functions.

General topics

These are kept for historical purposes. Please use the issue tracker to provide new suggestions.

• Roadmap as agreed after the Harvest meetings.
• Ideas for future work: Feature requests
• Queries to support: Query Brainstorm
