One of THRON aims is to guarantee content uniqueness. This it the reason why, regardless its context of use (either a folder, an embed or an application), the content is always the same and it is recognizable thanks to a unique identifier (xcontentId). Any changes or updates on the content from any user who can access it will always be visible in every context in which the content is used.
Is it possible to publish the same content in several categories? Are they copies or is it the same file?
