A note on the downloadable data provided by SIL for the ISO-639-3 codes: For quite some time one of the tables in the zip files provided at https://iso639-3.sil.org/code_tables/639/data was broken (contained lines with inconsistent numbers of tabs but no content - which is the reason for this line https://github.com/clld/clldutils/blob/93d3789175103d6f60eb33ef7f4779177ec9993f/src/clldutils/iso_639_3.py#L52 in my processing code). I notified SIL about this but never got an answer. Given this, I wouldn't have too high hopes in an RDF dump provided by SIL.
