What (if anything) can be done about widespread metadata errors in indexes of multi-part films?
On the indexes of Hungarian civil registrations in Szabolcs county and environs, the event location was assigned by a post-processing step. (The indexers had and have zero input on the location field.)
The problem is, this process Did It Wrong a fairly significant portion of the time, because on multi-part films, it assigned the location of the first part to every entry on every image on the whole film. This means that often, the location is in entirely the wrong county, many miles away from the correct place.
For example, Film # 004531463 has three parts. Part 1 (images 1 to 99) is death registrations from Rudabánya in Borsod county, so that's what's under "Birthplace" for all of part 2 (images 100 to 407) and part 3 (images 408 to 786), which are actually birth registrations from Gönc in Abaúj-Torna county (https://www.familysearch.org/ark:/61903/3:1:9Q97-Y337-PL6?i=101&cc=1452460). Gönc is 30 miles east of Rudabánya as the crow flies. (The records ended up on the same film because the places are now both in the combined-remnant county of Borsod-Abaúj-Zemplén.)
I have two questions:
1. What can be done about these widespread errors? The civil registration indexes are (inexplicably) not correctable, so going at it piecemeal is (perhaps luckily) not an option, but it is disheartening to know that large parts of this index have been rendered essentially useless by this post-processing error.
2. Has this post-processing step been corrected, or is the first part's location still being assigned to the whole film in the ongoing indexing of Budapest civil registrations?
