Hi! Not sure whether I even have this in the correct category, but I hope so.
I try to make sure that images/documents I share on WikiTree are okay in regards to copyright and sharing. I'm Australian, so I primarily use Australian repositories like Trove, where I know exactly what I can and cannot do with what I find. However, I've recently started accessing fantastic items from the Archives in Hessen, Germany, and I'm just not clear on whether they can be re-shared elsewhere online -- I've read their copyright page and it just says: "Some of the contents on this Internet site are protected by copyright. Images, diagrams, texts, marks or other works and services may wholly or partly be subject to third-party rights", which is neither explicit nor helpful. The German version of that page appears, unsurprisingly, to say exactly the same thing. When you download a document, it has a little footer connected with Archive information on it, suggesting that they expect it to be shared, but again, there's nothing explicit about this, it's just me making an inference.
I would love to be able to upload things to Wikitree; for example,1946 Kennkarte applications (see: my great-grandmother's application), which contain a trove of data (address, occupations, to whom married, physical descriptions, etc), and which also include photographs! Photos are always so exciting. But I'm just not... sure. At the moment I'm just providing links, and referencing as usual.
Does anyone have any better knowledge on this? Or know what the usual practice is with archival documents from Germany? Those photographs would be so amazing to add!
