Basic architecture

These pages describe the various components of the software behind the Connexions system without getting into implementation details. The system architecture is divided into four major components:

Two types of content can be published in Connexions: modules and collections. Both modules and collections are saved and managed in XML languages created for this purpose.
The repository provides storage and access to Connexions content. We currently house open educational resources for all age levels from around the world, with the amount of published content growing daily.
Editing environment
Connexions provides a web portal for the collaborative creation and management of materials. The editing environment includes several ways to access and edit content.
Lensing Systems
Users can highlight exemplary content within our powerful lenses system. Expert vetting of content allows user-driven quality control on Connexions modules and collections.

Open source development

We are an ongoing open-source development project. If you are interested in more detail about our architecture, or want to get involved with developing, please see our development sites:
