Package: rotio 0.1.0

rotio: Pure-R 'OpenTimelineIO' Document Model

A dependency-light 'OpenTimelineIO' (OTIO) <https://github.com/AcademySoftwareFoundation/OpenTimelineIO> document layer in pure R. Provides constructors for the OTIO object model (timelines, tracks, clips, gaps, media references, rational times and time ranges), functional builders that return new objects, and readers and writers for canonical '.otio' files through 'jsonlite'. The optional 'RcppOTIO' package validates output against the real 'OpenTimelineIO' C++ library. No compiled code.
