What is different between Aspect and Associations in context of Content Model?

Answer 1

It is quite easy actually:

• An aspect is simply a collection of properties that can optionally get added to a content of a specific type. (ie: an aspect called webable for content that can be published to the web, with one single property indicating if it is already published true / false and one other with the date of last publication)

• An association is a link or a relationship between two content types (ie: link a generated pdf file to the original docx file/template)
