Editing Learning object (section)

Before any institution invests a great deal of time and energy into building high-quality e-learning content (which can cost over $10,000 per classroom hour),<ref>{{cite journal | doi=10.24059/olj.v5i2.1880 | title=The Costs and Costing of Networked Learning | year=2019 | last1=Rumble | first1=Greville | journal=Online Learning | volume=5 | issue=2 | s2cid=10610860 | doi-access=free }}</ref> it needs to consider how this content can be easily loaded into a [[Learning Management System]]. It is possible for example, to package learning objects with [[SCORM]] specification and load it in [[Moodle]] Learning Management System or [[Desire2Learn]] Learning Environment.

If all of the properties of a course can be precisely defined in a common format, the content can be serialized into a standard format such as [[XML]] and loaded into other systems.  When it is considered that some e-learning courses need to include video, mathematical equations using [[MathML]], chemistry equations using [[Chemical Markup Language|CML]] and other complex structures, the issues become very complex, especially if the systems needs to understand and validate each structure and then place it correctly in a database.{{Citation needed|date=April 2008}}
