MediaWiki architecture document

This project's goal is to write a comprehensive document about MediaWiki's architecture, and the decisions in its history that led to its current organization.

Rationale
In August 2011, Greg Wilson, editor of the Architecture of Open Source Applications book, contacted the engineering department of the Wikimedia Foundation to offer to include a 5000-word chapter on MediaWiki in volume 2 of the book.

The Architecture of Open Source Applications book presents case studies of the architecture of large-scale open-source projects; the content is freely available under the Creative Commons Attribution license.

It rapidly appeared that a document would also be generally useful to help new developers dive into MediaWiki development. For this reason, Guillaume Paumier and Sumana Harihareswara accepted the responsibility of leading the collaborative writing of the document by the MediaWiki community.



Add your piece.

This project will be successful, and helpful to new developers, only if the MediaWiki community shares its historical knowledge, stories and opinions on the architecture of MediaWiki.

Please take a few minutes to share what you know and what you think. Future generations of MediaWiki developers will thank you.
