A market that does not stop at the border
Anyone based in Konstanz has customers on both sides. That is not a translation question but a structural one: prices, legal notices and sometimes the offering differ, even though the language stays the same.
TYPO3 offers two routes for that. A shared version with targeted departures, when little differs. Or a separate site per market, when the presence should stand on its own, with its own domain but the same installation and the same upkeep. What needs settling technically is set out under site configuration.
A university means many editorial teams
The university and the university of applied sciences bring a familiar constellation: many departments, distributed responsibilities, differing expectations of how current things should be. A central team cannot maintain that, and should not have to.
The answer lies in fine-grained permissions per area of the site, supplemented by a tailored editing interface. What nobody in an area should use does not belong in the list in the first place; that reduces questions more effectively than any manual. How it is configured is set out under TSconfig.
On top of that comes the accessibility obligation of publicly funded institutions, and it applies per language version. There is more under TYPO3 accessibility.
The distance, named honestly
After Freiburg, Konstanz is one of the furthest points in the area we cover. We do not gloss over it: around two hours of travel, planned meetings rather than spontaneous visits.
For the project work that is immaterial, because it runs remotely anyway. For expectations it matters, which is why it stands here rather than in the small print.
