Yes, that is what I was referring to.
In regards to the information source: When you refer to size of datasets, for example, can you elaborate that? My understanding so far was if the creation of anything requires significant effort, then it is automatically copyright protected. So the size of the dataset does not matter as much as the complexity to generate it.
Am I mistaken?
Is there a list, reference, rule of thumb, something to read when copyrights might NOT exist?
