Authorship and composition, read through MIGNONNE.
“空をとべたら” is cataloged here as a written musical work, separate from any particular performance, recording or physical issue. The documented words and music are both credited to Taeko Onuki. Keeping these roles explicit makes it possible to follow the authors even when a performer’s name is the most prominent name on a release.
The catalog documents this work within Taeko Onuki’s 1978 album “MIGNONNE” through the artist’s track-specific credits and a recording-to-work relationship. The linked album essay is therefore the closest established context. This route follows recorded relationships rather than treating a similar title elsewhere as the same work.
The supplied graph contains 1 recording-to-work relationship for this work. Such a link identifies the composition represented by a cataloged recording; it does not collapse the work, that recording and every later edition into one object.
