Well, that would be an specific case. In this case, I think the best option would be to contact the Polish Heritage Institute and update as they update, and it would be great if they could provide the new data in a raw format. In all the other cases it is kept stable, and I think many institutions don't even remeber they have this information. Anyway, how would you do it to keep it constantly updated?

Well.. not so stable - at least in some countries. For example Polish
Heritage Insititute is constantly changing their list. This is just
because quite substantial number of new objects are added every year,
and also some of them are removed. This is mainly because during
communist era many objects were not considered to have a heritage
value (old factories, XIX century houses of noblemans etc.) and
actually they are, and some objects are allowed to be destroyed (if
they have minor importance and are immposible to be moved) or moved to
other places due to current construction works (epecially builiding
new highways). So, in 2009 Polish list increased from 61000 to
65000... and around 500 objects were allowed to be destroyed or
destroyed illegaly.
