Thanks for your reply, Nike. We appreciate it. Just to be clear, we're running Semantic MediaWiki.
I have a 'Context' property on a page. When initially creating the translated versions of the page, the property and value of this property ('situation') is copied correctly. However, what we aim for is that, when the value of the property of the source page (if we change the Context property's value to 'role' in the source page source code) - or if a new one is added - that the derived translated page automatically reflect this change as well.
In essence, we want it so that if properties are added, edited or deleted on the source page, it also automatically does this on the translated pages. Consistent semantic properties are a staple of our current work philosophy, and we want our users to have to do as little work as possible.
