Hi all - thanks for the improvement addressed in
In arrow 2.0 spatial data (class sf) now retains metadata at column level, but still does not roundtrip correctly as metadata (attributes) are lost at the level of individual elements of the list-columns; at least I think that is the problem as that is where I can see changes in the metadata.) Is this something that is addressable?
See reprex below on what happens + what attributes exist at the element level.
FWIW a workaround with spatial data using sf would be to convert to WKT before writing it out (sf::st_as_text()). It might be useful to note this somewhere in the docs.
This is using arrow 2.0 and sf 0.9-6.
