In Moodle 2.0 is a new functionality for course exchange via hubs. Integrated is a list of educational subjects. This list bases on the Australian Standard of Education (ASCED).
Here is a discussion at Moodle. org. The information about all the terms are available here and in the attached document. Starting at p.94 you'll find explanations for all terms used in Moodle. It is very helpfull to read this information for translation of the terms.
Some of the subjects are special regional terms used in Australia and there may be no term in your language. Than you can try to let in untranslated or find a similar translation with brackets that it is an australian subject.
