OLX (open learning XML) is the XML-based standard used to build courses for the edX Platform.
With OLX, you can:
Move content between instances of Open edX.
Create course content outside of edX Studio, including by conversion from other content formats.
Ensure content remains free of proprietary encoding and allow portability.
OLX is based on XML. XML, or Extensible Markup Language, is a set of rules for creating documents in a format that is both human-readable and machine- readable.
To work with OLX, you should have a strong understanding of XML. This document presumes you understand XML and can use tools to create and edit XML files.
For a primer on XML, see the Wikipedia XML entry .
