Lesson plan

ExpressionEngine

ExpressionEngine (often abbreviated EE) is a free and open-source content management system written in object-oriented PHP and using MySQL or MariaDB for data storage. It is developed and maintained by Packet Tide, LLC, and distributed under the Apache License 2.0. Unlike systems that ship with a fixed content model built around posts and pages, ExpressionEngine provides no predefined content types. Creators define their own structures using channels composed of custom fields, then render that content through a tag-based template language. This design has made the system a long-running favorite among agencies and developers building bespoke sites with great extensibility, while contributing to a reputation for a steeper initial learning curve than mass-market alternatives. ExpressionEngine began as pMachine, a weblog application released by Rick Ellis in 2001. The first version of ExpressionEngine was released in 2004 as commercial, closed-source software, and it remained a paid product for roughly fourteen years. In 2018 it was relicensed under the Apache License 2.0. Ownership changed twice in rapid succession between 2018 and 2019 before settling with Packet Tide, which continues to develop the platform.
