Maven metadata: slf4j-api
The same file for a library with a much longer release history — useful for seeing how these documents grow.
Three times the size of the commons-lang3 metadata and identical in shape. Comparing the two is the cheapest possible demonstration of a structural diff: same paths, different cardinality.
The version list here spans well over a decade, which makes it a realistic test of anything that sorts version strings.
