Hi Jeremy, it’s somewhat surprising, but XQuery itself has no database semantics. This is the reason why the implementation of fn:collection is pretty much implementation-defined [1]. In BaseX, the function checks if the specified URI matches a database. If negative, the URI will be resolved against the file system. I’m not sure why it didn’t turn out to do so in your scenario, but I’m pretty sure you’ll find some answers in our Wiki article on BaseX databases [2]. If not, feel free to give us some more feedback.
