Entering location and source data for Rozvadov church records

Thanks to the help of a family member, I found the marriage record for my great-great-grandmother’s parents, Theresia Dorfler and Johann Zitzmann, in the actapublica.eu archives for Rozvadov (book 18, folio 15). My question is, when adding this event to my genealogy database, how do I cite this source? Is it a government archives website, or a private company? Also, how do I find out what jurisdiction(s) Rosshaupt/Rozvadov was in at the time (1865)? I’ve been told it’s in the district of Eger, kingdom of Bohemia, in the Austria-Hungarian Empire. Would I just enter it as Rosshaupt, Eger, Bohemia, AHE? I’m still very new at doing research in this part of the world, so please excuse my ignorance if this is an easy answer. Thanks, Brandt
