Under Development. NOT ready for serious use
OpenQA, Open Question Answer, is an opensource REST server that provides core data structure and REST service for question and answer, modeled after StackOverflow, Quora and Zhihu (知乎).
The purpose of OpenQA is to provide a solid backend for developers to develop Question and Answer. It ** DOES NOT ** aims to be an QA site with full featured UI that competes against StackOverflow, Quora or Zhihu, but aims as backend for developers to develop their own QA sites that suites their own needs.
OpenQA Core is the center of OpenQA, a REST server developed with Clojure. It uses Postgresql as datastore and uses ElasticSearch as search engine.
OpenQA Core focuses purely on the essentials of an Question and Answer site:
- Create / Update / Delete / Query Questions, Answers, and Comments
- Upvote / Downvote Questions, Answers
- Drafting / Publish / Delete Drafts
- Search questions and answers
A Web frontend will be developed but itself is not considered a core component, as least initially.
It was designed with following principle:
Flexible data strucutre that can power complex QA sites
The core data structure is built with following features:
- domain : allows developers to split QA data into different domains, and deploy domain data to different database instances.
- topic: subject topics for organizing content.
- tags: used for functional tags used by end users.
- meta_tags: used for meta tags used by developers.
- folder: user as an extra layer for organizing content.
- upvote_count / downvote_cout: used for upvoting / downvoting functions.
- seq_id: used to indicate time squence of Questions / Answers / Comments with the same domain.
Minimal core
The core only provides prebuilt question and answer content management services, and aims to provide these services fast, correct and extensible.
It dosn't do the follows:
- User management. All the core needs is uid.
- Security. Developers should bring in security features.
- Data backup and restore. It purely relies on database to provide data backup and restore functions.
